Co-organized
by the Micronutrient Initiative and OXFAM Canada
Meeting
Goal, Objectives and Expected Outputs
Goal
The goal of the meeting was to assist in the development of ideas
and strategies for the field testing of community-based food fortification
of cereals and the identification of related needs and support activities.
Objectives
-
to share information about community-based fortification-related activities
being planned or undertaken by the agencies represented at the meeting;
-
to provide information about the technical aspects of milling and fortification
of cereals (e.g., mill operations, blending systems for making and adding
premix, establishing levels and forms of micronutrients to be added);
-
to identify and discuss key considerations to be addressed when field
testing the feasibility of community-based fortification of cereals
(e.g., social, economic, logistic, training, community education and
involvement, monitoring and evaluation); and
-
to identify steps to be taken and needs to be addressed in order to
work in a systematic, effective way to further advance and support efforts
to develop and field test small-scale community-based fortification
of cereals.
Expected
Outputs
-
to gain a better understanding of the technical options available for
fortification at small-scale milling operations;
-
to identify specific technical questions that need to be answered in
order to proceed with field studies, and to identify areas where a knowledge
base exists and the gaps;
-
to outline specific plans for field testing fortification at small-scale
milling operations;
-
to outline commonalities that could be addressed by groups involved
in the field testing (should we strive for a common protocol?);
-
to make recommendations on improving networking and communications between
those interested/involved in fortification at small scale milling operations;
and
-
to outline a work plan (i.e., at least an outline of key activities)
over the next 1224 months aimed at advancing efforts to test/introduce
fortification at small-scale milling operations.
Information
Sharing
Following
the welcoming of participants, and the presentation of the meeting's goals,
objectives and expected outcomes, each of the participants shared with the
group a brief explanation of their involvement (current and/or planned)
with small scale fortification. This is briefly described below.
Oxfam
Jim
MacKinnon spoke about how OXFAM is starting a pilot program in Zimbabwe
and Mozambique. They are targeting 16 communities in 5 districts, all
border towns. The main activities of this project will be:
1) community
gardens;
2) promotion
and re-introduction of small grains (Zimbabwe is dependent on maize);
3) fortification
of small grains;
4) a
health component (malaria) related to the baseline survey; and
5) capacity
building among 4 NGOs.
The
management of this project will be by OXFAM in collaboration with 4 NGOs.
Through this collaboration they will try to establish a set of "lessons
learned", as different NGOs bring to the project different expertise.
The
baseline study for this project was done in July, 1997, and they looked
at (i) for the 5 districts what information existed. For this they
used UNICEF data; and (ii) the results of a community-level questionnaire
on health-nutrition at the household level. To carry out this household-level
study, they did not use any biochemical indicators (reason: the prevalence
of HIV/AIDS in the areas of study is 3050%, and OXFAM is reluctant
to take any actions that involve drawing blood). This questionnaire addressed
diet, income (its source, and how it gets spent), incidence of malaria,
and HIV/AIDS.
The
participant from OXFAM looked to the group for feedback on what they thought
the sustainability of this kind of activity would be.
CIDA
The
representative from CIDA, Barbara MacDonald, expressed to the group that
NGOs play a special role in these kinds of programs as they can have access
to areas government cannot, and they have a unique ability to monitor
activities. CIDA wants to be supportive, especially since fortification
is very important and suggests that the Canadian experience be used as
a guide.
CARE
Canada
Jaqueline Wood from CARE Canada described how CARE is beginning
a community-level fortification project in Zimbabwe. This is a new area
for CARE, and they are looking for guidance from others' experiences.
The Zimbabwe project will address 3 components:
1)
women's groups-agro processing, small scale processors, millers;
2)
technical issues of fortification, appropriateness of technology, and
compliance; and
3)
social marketing at the village level, cost recovery, and sustainability.
CARE
is also extensively involved in programming with Canadian food commodities
in emergency distribution and development projects. These are potential
avenues for further fortification work.
World
Vision Canada
World Vision Canada, as explained by Janet-Marie Huddle,
is planning community-based fortification programs in Malawi, Tanzania,
and Guatemala.
In
Malawi the project focus is on weaning foods, producing a maize and soya
blend with premix added. WFP in Malawi agreed to provide the premix for
the World Vision mill operating within the MICAH program at Domasi. The
issues they will address are: product marketing, sustainability, and seasonal
demand of the product (if people are producing their own they don't need
to purchase it). The buildings are finished, the mill is constructed,
and production is ready to start. There is to be a workshop in Malawi
in September 1998 regarding fortification.
The
Tanzania project is still in the preparation stage, but the baseline studies
are done. World Vision is looking for input on this activity.
In
Guatemala, the project is in the conceptual stage. They plan to look at
maize products in the existing community bakery and to implement fortification
at the bakery level. The target population will be young children. The
representative from World Vision asked the group if they think this will
be possible. The group conceded that you can fortify at the community
bakery as well as at the household level. It was suggested that in principle,
people may grind maize at home and add a sachet of premix.
Aga
Khan Foundation
The representative, Tony Breuer, explained that Aga Khan Foundation
is primarily involved in emergency response activities. He chose two examples
to illustrate the work they are doing:
1)
Kyrgyzstan: In this country, the population has both a high nutrition
and education level. The crisis now experienced resulted because 80% of
the food consumed was brought in through the Soviet system, and agricultural
productivity is very low. Aga Khan bought wheat from Central Asia to import
to Kyrgyzstan. The project also includes teaching the population to do
sustenance farming, needed due to the break up of State farms. The program
has moved very quickly due to the pre-crisis high standard of living.
2)
Afghanistan: The nutritional status of the population is very low, and
access to markets is very limited. Narcotics trafficking is very high,
and there is substantial political instability. Aga Khan Foundation has
started to distribute wheat, but still has to determine health and nutritional
status of the population (the intent is to use biochemical indicators)
and will need to do an agricultural and income survey. A site visit to
the mills has revealed that the general consensus is that local millers
are shortchanging the farmers because the millers take up to 10% of the
grain as their fee. The Aga Khan Foundation wants to move away from bringing
the product in, instead they want to develop this at community level.
OMNI/USAID
Penny Nestel told the group that most of OMNI/USAID's work
has been done on the large scale, at the national level. Their perspective
is that food fortification is part of dietary diversification interventions.
Over the last 20 years, OMNI/USAID's involvements have been:
1)
national level sugar fortification with vitamin A in Central America,
and Zambia;
2)
wheat fortification with iron in Sri Lanka;
3)
developing and testing sprinkles to add zinc, vitamin A and iron to complementary
food. The target population of this intervention is young children. Dr.
Zlotkin from University of Toronto is conducting efficacy trials in Nicaragua,
Ghana and possibly India;
4)
quality assurance, iron and vitamin A content of foods;
5)
quality assurance of wheat flour fortification at the bakery level, but
would like to move to the milling level.
Micronutrient
Initiative
Jenny Cervinskas presented an overview of MI's work in this
field, and summarized it according to MI's thematic areas as follows.
Advocacy
and Alliance Building: In the area of advocacy and alliance building,
MI is active on both a national and regional scale. In Latin America,
MI has been working with ALIM (Association Latin American Millers) to
prepare a declaration on the fortification of flour with micronutrients;
in the Middle East MI is working to initiate a dialogue between national
governments and millers; in Asia, food fortification advocacy efforts
are focused on Bangladesh, India, Nepal and Pakistan; in Africa MI has
been working with the World Food Program in Malawi, Zambia; Zimbabwe;
and on a global level MI held both the Ottawa Forum and the IUNS-Food
Fortification Workshop (both of which were meetings to promote public-private
sector dialogue), as well as being actively involved in the production
of advocacy and information materials.
Development
and Application of Technologies: In terms of the development and application
of technologies activities relevant to this meeting, MI is currently involved
in the development of a blending system to evenly distribute premix in
milled cereal.
Capacity
Building: MI's capacity building efforts include the training of millers
in Latin America, and the production of various technical documents/information
texts (e.g., flour fortification booklets; directory of premix suppliers;
standards for premix and sample tender forms).
Operational
Issues: Some of the operational issues MI is addressing on this topic
are evident in MI's field testing of small scale milling (Zambia), and
the exploration of opportunities for fortifying cereals used in refugee
feeding in sub-Saharan Africa (with Refugee Policy Group).
Discussion
Issues
to be Addressed
Following the presentations by participants, the group did a brainstorming
exercise and generated a list of issues that need to be addressed in any
attempt to fortify cereals at the small scale. This is presented below.
-
The purpose of fortification should be explicit. Is it to treat disease
or to improve nutrition?
-
Which micronutrients are to be added?
-
What is the relationship between existing and newly-introduced interventions?
-
What is the target group?
-
What is necessary to start an intervention? What essential information
is needed to start? Time available will need to be balanced with desire
or ability to achieve accuracy.
-
Will one strive to demonstrate efficacy or effectiveness? It is likely
that it will be easier to demonstrate efficacy than effectiveness.
-
Do strategies differ depending on the type of cereal or small grain
to be fortified?
-
Who controls the interventions, and how?
-
Does the term small scale also include household level milling and/or
fortification?
Definitions
Since the discussion at times moved to addressing food fortification
at large scales of operation, it was urged that the group focus on small
scale operations. This led to a questioning of definitions. What is meant
by small-scale? By community? For the purposes of this meeting it was
agreed that small scale is defined as those milling operations with
a capacity of producing 3 tons of milled cereal per day, or less.
Time
Frame
The expectations about the time frame for small scale fortification
were questioned. It was asked "Do the participants view small scale fortification
as a long term goal or an effort to be pursued just until one gets the
macro scale up and running?". Some participants from the NGO sector said
they viewed small scale efforts as being a long term goal, requiring a
long term process one needing a process of refinement over time.
The view was that we will monitor as we go along, and will start to be
able to answer questions as a result of the experience gained.
One
participant said that this viewpoint makes it a food-based solution versus
a technology-based one. In pursuing food fortification at the small scale
mills one is not aiming to change entire dietary practices but instead,
seeking to complement and improve the existing diet.
It
was suggested that the discussion be limited to small scale, possible
emergency level since that is where we will be starting, but keep the
assumption that this is to be increased coverage.
Food
aid was briefly discussed, with one participant noting that feasibility
studies could be done; for example, in emergency situations where cereal
food aid is being distributed. Often, this food aid is imported cereals
that are milled locally. Another pointed out that cereal flours can even
be fortified to Canadian standards prior to export. The possibility of
using micronutrients for disease control in refugee settings was suggested.
Parameters
for discussion in this meeting were therefore set as:
- Food-based
strategies;
- Small-scale
milling operations, defined as less than 3 tons per day;
- Small
scale to include community level;
- Fortification
of (Canadian) food aid is to be the topic of another workshop.
Sustainability
Concerns were expressed about the sustainability due to the small
scale of the operations. Small scale will mean that milling operations
could be very crude, that there is limited access to the milled product.
The limitations were acknowledged, with the point made that if it is found
that the milling system itself is not appropriate, then alternatives will
need to be explored. The resourcefulness of millers who do currently fortify
their products was mentioned. It was noted that cement mixers are being
used to fortify some blended foods being produced in Africa (and there
is nothing wrong with this practice). The need to ensure that monitoring
is done was mentioned.
Household
Level Food Fortification
It was stated that it will be important to define the composition
of the premix according to use/ target group, and that toxicity of household
level fortification is a serious issue. One participant said that household
level efforts should be directed at preschool children, and viewed as
a targeted intervention. Thus, the objectives of household level fortification
are different from food fortification at the small-scale level. If efforts
do take place to fortify foods at the household level, we need to think
about what we are telling parents, what we are saying about nutrition.
This can help put mothers back in control of what their child eats. This
can be more empowering than to encourage mothers to "go get your iron
drops every 2 months." Besides micronutrients, there are other important
factors.
It
was mentioned that preliminary work is being carried out in Bangladesh
to develop a multiple-fortified sprinkle. It was stated that this concept
can work in Bangladesh because of existing infrastructure of community
health workers, whereas it would not be feasible in a refugee camp setting
that does not have much infrastructure.
The
importance of educating people before any new technology or product was
introduced into their households was stressed. "Don't jump the gun; the
buy-in is needed," stated one participant.
Point
of Intervention
Regarding the possible points where fortification could take place,
it was pointed out that one needs to examine the distribution levels and
ask "where can we intervene?". The preferred choice is likely to be at
the national level or central milling, with the second one being to fortify
cereals post-milling, before distribution, and the household level as
the last resort.
The
same question of "where can we intervene" can be applied to cereal food
aid. Since supplies generally come from outside, the need is to think
of an intervention point. Where does the grain get milled? Does it even
get milled? We know that some people eat whole grains, cooked and mashed.
In any case, besides asking where one can intervene, one needs to ask
"how can this be done?".
Acceptability
Acceptability and use of the cereal needs to be considered. It
was mentioned that blended foods are more acceptable since it is like
porridge, a familiar food, and that distributed grains can have a market
value, therefore are sometimes sold to buy more familiar foods.
It
was pointed out that it might be possible to envisage a situation where
a number of products are fortified, for example, that cereals are fortified
at a large or smaller scale of production, and that household level products
(e.g. sprinkles) would also be available, specifically for use by mothers
in complementary feeding.
The
question was raised "How does the education/community awareness and training
needs differ when speaking of household level food fortification efforts
versus small-scale efforts at a community level?".
There
is a need to establish who the target is for any effort to fortify food.
One cannot design a food for the target and use it "across the board."
Micronutrients are not target-specific; micronutrient deficiencies are
not a problem limited to children. A general fortification program will
not address the needs of the vulnerable group aged 6 months to 3 years.
Can
a general fortification program deal with the problems of the young child?
Safety is an issue and is affected by the concentration of the premix.
Premixes need to be tailored according to their use.
Techinical
Presentations
The day continued with two technical presentations: the first
on blending systems, and the second on premixes.
I:
Blending Systems
Presented by Mr. Ravi Philar
From
Mr. Philar's experience, specific criteria and conditions are necessary
for successful fortification at the small scale mill. These are:
-
The blender (i.e., the vessel in which the maize meal would be blended
with the fortificants) needs to be rugged, inexpensive, portable, and
have few moving parts (this would decrease the chances of breakdown).
It should be easy to repair locally. It should be manually operated:
fuel or electrically driven operations would be prone to shortages or
shutdown, respectively.
-
Effective blending should occur in less than 5 minutes. It was noted
that this timing was based on an assumption about how long a period
would be acceptable to the person doing the blending. The premix (fortificant)
would need to be uniformly distributed in the milled maize, therefore
the consistency of the premix must match that of the milled maize.
-
Consumer acceptability of the blending concept and the actual practice
would need to be secured. It is assumed that it will be the customer
him/herself who will control and/or do the blending and that a simpler
design is more desirable.
-
The cost of both the blender and the premix must be affordable, as the
costs will likely eventually be passed on to the consumer.
Mr.
Philar stated that the overall objective of the work he has done under contract
to MI is to achieve sustainable methods of fortification locally, and that
the specific objectives of his work with MI in Zambia and Malawi were to:
-
identify the technical requirements for fortification (how big, how
does it work);
-
make use of existing, available, and appropriate technology;
-
test the ability of each blending system to evenly distribute the fortificant;
-
estimate capital cost, personnel and training needs, and infrastructure
needs (e.g., water wheel needed?) associated with each blending system;
-
assess community acceptance of these systems, and identify possible
barriers; and
-
propose an action plan.
Existing
maize mill conditions in Zambia were described to give an idea of the context
within which we are working. The milling methods ranged from diesel or electric-driven
mills to hand pounding. The milled product is of coarse consistency. The
milled product is separated, fine from coarse, by cyclone or direct feed
discharge, and this results in an approximate 10% loss of product: you can
usually see by dust covering the workers. This loss of product can be an
issue, because the miller does not want to lose any of the premix, which
is expensive. Generally, mill operators have minimal training and the mill
conditions were not sanitary.
The
capital cost of equipment for a typical mill is approximately CAD$1,700,
and the milling cost to the consumer for an average batch (20 kg) is approximately
$0.20$0.33.
Mr.
Philar then explained how MI went about designing and testing various
blenders that were meant to be suitable for the Zambian conditions described
above. First (with the aid of a video and the actual presence of some
of the blenders) he described and demonstrated the various blending systems
that were designed. Five in all were developed. The blenders range in
cost and sophistication from a US$950 hand-operated stainless steel ribbon
blender originally developed for iodizing salt, to small plastic pails
(with or without baffle inserts) that cost U$ 1-3 each, and that can be
rolled to and fro on the mill floor. Also in a lower price range (approximately
US$15) was a plastic pail with an integral baffle that would allow for
movement up and down, as well as along the circumference, while being
rolled along the floor (this pail, called the ODJOB, is commonly used
to mix cement), and a blender with a paddle to be placed directly into
the pail and manually stirred (cost about CAD$1520).
From
MarchMay 1998 blending trials took place in Ottawa, Canada in which
the five types of blenders were tested to determine the efficacy of each
method for blending the premix with the maize meal. Maize meal that was
milled to an 80-mesh particle size in a hammer mill at an Ottawa feed
facility was used. A premix powder containing iron (as ferrous fumerate),
vitamin A, thiamine, riboflavin and niacin was supplied by a US-based
firm. The premix (developed specially for use in fortifying maize meal
in South America) was added at the rate of 25 g per 100 kg maize meal.
Using a sampling protocol developed by a scientist at Agriculture Canada,
different batch sizes (i.e, 10, 15 and 20 kg) of maize were tested, with
samples of blended maize taken at intervals of 1, 3, 5 and 10 minutes.
One sample per quadrant and two samples at full depth were taken. The
samples were then sent to an independent laboratory to determine the concentration
of iron in the feed and the fortified maize. While the analysis of the
data is still not completed, Mr Philar presented the early results emerging
from the blending trials.
The
preliminary analysis suggests that satisfactory blending can be achieved
in 3 to 5 minutes by three of the blenders. The hand-operated stainless
steel blender gave the best results. Good results were also obtained from
two other blenders but they had the disadvantage of a larger variability
in the efficacy of mixing.
Ms.
Cervinskas said that after further analysis is done to determine which
blending system is most efficient and the costing of the different methods
done, MI would be able to share the results with interested parties and
also share the equipment design and fabrication specifications. It is
expected that field testing of the recommended blending systems will be
started in Zambia soon.
II:
Premixes
Presented by Mr. Quentin Johnson.
Mr.
Johnson explained that there are two types of premixes: (i) those that
are related to cereals such as wheat and maize; and (ii) those that are
related to unimix.
Those
related to cereals are added in low levels to the cereals (i.e., 0.18
mg of premix added to 100 mg of wheat), and are composed of nutrients
such as iron, B vitamin group, and folic acid, whereas those related to
unimix contain a large range of nutrients. Issues to consider with unimix,
therefore, are the interactions between micronutrients (e.g., vitamin
A reacts with vitamin C).
Using
the example of iron, he talked about the how the micronutrients are added
and in what form in order to address the issue of micronutrient interaction
and the stability of the micronutrient-fortified product. When trying
to determine which iron source should be used (e.g., reduced iron vs ferrous
fumerate) there is a debate between nutritionists who know that ferrous
fumerate is more bioavailable than reduced iron, and food technologists
who know that reduced iron is more stable. His solution is to use both
sources, but increase the amount of elemental iron to compensate for low
bioavailability. In addition to the form of the micronutrient chosen,
it should be noted that stability/discoloration of the product can be
affected by the cooking method as well.
Therefore,
in order to purchase an appropriate premix for your project, Mr.
Johnson explained that the premix supplier will need to know what nutrient
composition is desired, what cooking method will be used, and what will
it be added to (e.g., wheat, sorghum).
Accessibility
of the premix itself can affect field level success of the fortification
efforts. Using the example of the large-scale production of fortified
cereals in the WFP program in Zambia and Malawi, where 1 kilo of premix
is added to 1 metric ton of flour at the mill level, the delivery time
of the premix is approximately 6 months from the supplier, which is in
South Africa. In addition, in some cases the mills may have to pay for
the premix up front.
Quality
assurance and monitoring is necessary to avoid toxicity, therefore you
need to know the composition/concentration of the premix as it leaves
the factory. Quality can be controlled by having the premix in dilute
form, then added accordingly to obtain the levels desired. The question
can be "how do you monitor the fortificant levels when stability of the
premix varies in the field?". Mr. Johnson stated that semi-quantitative
spot tests can be conducted, i.e., elemental iron will show up; however
vitamin A testing requires the use of hydrochloric acid (a very strong
acid), which is not "field-friendly."
When
developing Action Steps, the group wanted to establish some premix standards
to serve as a basic guideline, or possibly a premix designed for universal
use. Mr. Johnson feels that would be extremely difficult to do so globally,
but might be possible for specific geographical areas due
to
similarities in diet and cooking methods.
MORE ON PREMIXES...
Can a premix be designed for universal use, or, perhaps, be
designed for a general pattern of food consumption? This question, raised
at the end of day 1, generated a lot of interest, the answer being highly
relevant to those ready to embark on feasibility trials, or indeed, anyone
procuring premix for fortification efforts.
Given
this interest Dr. Beaton was asked by the workshop organizers to provide
his views about this, and comment on what needs to be considered when
selecting types, levels and forms of micronutrients for a premix. A summary
of Dr Beaton's "mini presentation" is provided below.
The
following key factors need to be considered when selecting types, level
and form of micronutrient to add to a premix:
- Recommended
dietary intake (RDI);
- Estimated
consumption of the grain (i.e., need to know what the diet consists
of; what the food practices are) and the variability within the population;
- Estimated
loss of micronutrients;
- Other
ongoing interventions.
Dr.
Beaton urged that one must first establish some ground rules, such as
the following:
Start
with energy supply and try to ensure an adequate intake of food, then
worry about nutritional quality. Realize that energy intake and nutrient
intake are not necessarily correlated. That is, adequate energy intake
is a necessary, but insufficient, prerequisite to an adequate nutritional
situation.
Conceptually,
the concern is in meeting the nutritional needs of the general population;
so, the target group is the members of a household. It is usual in a household
that members share the same food supply.
Do
not expect fortification to treat an existing nutritional problem; it
is a means to prevent nutritional deficiency.
The
assumption is that there are no widely divergent diet types in the population
and that the level of fortication added will meet the needs of those who
eat the fortified product.
This
approach can only be used when fortifying staple foods. Conversely, there
are settings in which a general premix should not be approached.
Dr.
Beaton stressed that the goal in terms of nutriture must be known in advance.
Is it to prevent classical deficiency diseases, or is it to meet all know
functional needs, or is it to build and maintain normative stores? These
imply different nutrient requirements and different additions to
foods.
Dr. Beaton urged that one not set the goal at simply preventing clinical
malnutrition. The diet should be at least adequate to cover functional
needs. The cost of adding sufficient additional nutrient to aim for normative
stores may be marginal.
It
is critically important that one recognize that nutrient needs vary among
classes of individuals (men, women, children) and, within classes, between
individuals. Total food intake and hence expected nutrient intake also
varies among individuals and classes. The design problem must be considered
under a probability approach the design of a "diet" that,
when consumed by various members of the household, is likely to be adequate
for all of them. That translates to the need to think in terms of nutrient
densities of the diet available to the household. In turn it requires
as a very early step, the establishment of a reference nutrient density
profile a target to be achieved with the aid of fortification.
We now have the tools to do this. Recognize that the nutrient density
profile will have to reflect the highest nutrient density need among the
classes of individuals expected to be in the population. This might most
often be the pregnant adolescent girl. It may not be possible to meet
all of her estimated requirements through a fortified diet and selective
direct supplementation is likely to be needed.
This
can be approached by system modeling.
In
the discussion that followed this brief presentation the point was made
that these issues have implications for how programs are measured. For
example, a false conclusion could be made since an inadequate energy intake
can negatively influence the ability to improve micronutrient status.
It
is accepted that information about the diet needs to be known; but, what
degree of accuracy is needed? There are some countries where quite a lot
of information is known about dietary patterns and food intake. For example,
in Malawi, over 70% of energy intake is derived from maize.
The
importance of product acceptability to the consumer was stressed. Once
this is known, then other measures, like intake of fortified food and
its distribution, can be done.
SMALL
GROUP EXERCISE
Following Dr. Beaton's presentation, the rest of the morning
of day 2 was dedicated to a small group exercise aimed at bringing out
design issues and factors related to the social, economic and technical
issues faced when field testing the community-based fortification of cereals
in settings where grain is brought to small scale commercial mills to
be milled in small batches (e.g., less than 25 kg).
The
participants were divided into two groups. A summary of each of these
discussions is presented below.
Group
1: Janice Johnston, Mahshid Lotfi, Jim MacKinnon, Penny Nestel, Alison
Greig, Ravi Philar, Janet-Marie Huddle.
Group
1 focused their exercise by first establishing the objectives of a field
trial, and then setting the group task as being that of developing the
action plan of steps to be taken when conducting a trial.
Objectives
-
to develop safe, acceptable, sustainable and affordable methods of fortifying
milled grains (maize, millet) processed as a service to farmers by local
millers;
-
to improve public health and nutrition status; and
-
to test the technology. This will involve considerations such as: Is
the technology acceptable? Are the nutrients met? Levels of dosage?
Action
steps needed when conducting a field trial
1) Gather evidence regarding micronutrient deficiencies. This will
involve determining what dietary intake data is available regarding micronutrient
deficiencies of importance as defined by government and nongovernmental
organizations (NGOs).
2)
Collect information on the following:
-
Ongoing supplementation programs
-
Dietary data. This could be done through a short (eg., four week) survey
by consultant
-
Quantitative data on food intake
-
Nutrient intake
-
Consumption of the staple to be fortified by age group
-
Energy intake. Is it meeting requirements?
-
Information needs? (Sources: HKI/IVACG)
-
Toxicity issues. A decision needs to be made about the safe levels of
intake. This could be a non-issue if dietary intake data is available
-
Nutrient level. The amount to be added needs to be determined.
-
Organoleptic changes that may result from the fortification. These may
be more significant than adequacy of intake
-
Preparation of the staple. It is important to know if it is, for example,
sifted or fermented. What method is used to cook the food?
- Estimation
of nutrient losses due to cooking. This might be done by a desk estimate
-
Estimation of any overage that might be needed to compensate for the
nutrient losses during preparation and cooking
-
Impact monitoring
- Cost
effectiveness. Specify the cost implications of meeting normative requirements
for nutrients. The intervention must be cost effective.
3)
Information needs related to milling.(This activity could be done in parallel
with others).
-
How is grain being milled?
-
Is it dry milled or wet milled?
- What
is the quality of the milled grain product? Its moisture content?
- What
is the quantity of grain milled?
- Storage
conditions. Is there infestation by bugs (i.e., iron dependent bugs)?
- Shelf
life 13 weeks shelf life has been reported. There can be
mold and mycotoxins
- Losses
(overage)
- Organoleptic
qualities of preferred product: meal, flour
- Current
regulatory and health inspection environment. May need the involvement
of the ministry of health, and ministry of agriculture
- Buy-in
of millers, community level associations
- Limiting
factors could be identified by focus groups with women, and millers
4)
Impact monitoring. A special issue is how do you capture the effectiveness
of each intervention when there are mixed ones in operation?
5)
Cost and marketing what are people willing to pay for fortification
and/or the fortified product?
6)
Testing the system (in parallel with step 7, below):
-
How will the micronutrients be added? Where? Using what equipment?
-
Premix manufacturer. Parameters to consider include colour and taste
7)
Acceptability:
-
This must be done in-country.
Group
2: Jenny Cervinskas, Jacqueline Wood, Barbara MacDonald, Ruth Ann, George
Beaton
Group
2 focused the exercise on establishing the main objective for a field
test and outlining the main activities to be completed to meet the objectives.
Their work is summarized below.
Objectives
-
to (develop and) field test methods of fortifying grains (maize, millet)
at small-scale commercial mills in a setting where farmers bring small
amounts (i.e., 25 kg) to be milled;
-
to identify the costs of such fortification to the miller, and
to the farmer. Costs will be in time, money, work, and family resources;
-
to examine the acceptability of the fortified product in terms of organoleptic
qualities (such as color and taste) and use of the product;
-
to determine the perceived benefits/costs/harm; and
-
to provide information to millers, farmers, and relevant ministries
about the study.
Assumptions
and Background
In undertaking the field trial it will have already been decided
that food fortification is part of the program strategy to improve health
and nutrition.
A
number of assumption are held, such as: the project bears the cost of
fortification (i.e., the milling cost will not be increased), and the
majority of staples are commercially milled.
Critical
issues
-
Technology how to field test it
-
What are the target nutrient levels?
-
How can the fortified flour be produced with nutrients wanted, at the
levels desired, and be acceptable?
Activities
Conclusions
Drawn from the Small Group Work
Points that emerged from the presentations of both groups were:
-
What are the community priorities? Often, nutrition is not one of them,
so the issue becomes how to make fortification and nutrition a community
priority.
-
A variety of dimensions will need to be examined social, cultural,
economic, logistical, etc.
-
Specialized technical assistance, often from more than one discipline,
is likely to be needed to fully conduct any trial. It was pointed out
that external technical expertise might be needed to collect some of
the above information. For example, an expert could be hired to help
conduct the dietary surveys, or to determine the level of micronutrients
to add.
-
The trials as a whole are complex, and will likely generally consist
of a variety of activities, with fairly extensive information needs.
These information needs will be determined in part by how much existing
data exists. For example, if extensive information is available about
the food consumption patterns and dietary intake it will not be necessary
to collect this data; if this is not available, then it may be necessary
to carry out dietary intake surveys.
-
It is likely that the use of qualitative methods will be highly relevant
in the field trials.
-
Who should pay for the premix? It was agreed that this could change
over time. Initially the cost could be borne by the project. This could
allow for "buy-in" from the millers and the community members.
-
Regarding the timing of activities it was recognized that some activities
could probably be done in parallel, while others would need to be sequential.
-
It was recognized that there could be an interest not only to fortify
maize but also millet or other small grains. Does this make a difference
for the blending? Are there any implications that need to be considered
if different grains are fortified?
-
The extraction rates for the grains may be important to know, since
these can affect the level of nutrient inhibitors such as phytates and
tannins in the milled product.
-
Regarding indicators and measuring the results of the feasibility trials,
it was noted that the time frame and resources (human and financial)
that are available to any feasibility study will set limitations on
the indicators to be selected. Measurements cost money; funds are often
limited. Also, it was emphasized that value judgements are made when
deciding on indicators, especially biological ones. For example, one
participant noted that the NGO in which he works does not want to adopt
what it judges to be invasive methods to measure project impact (e.g.,
drawing blood) and that taking blood samples itself represents a risk
in communities where the prevalence of HIV/AIDS is very high.
Next
Steps
As the closing session of the workshop, a plenary discussion
was held to brainstorm what steps could be taken to accelerate efforts
to test the feasibility of fortifying cereals in small scale milling operations.
Specific action points were identified and these are summarized in the

Summary
The
group confirmed their interest in testing the feasibility of fortifying
cereals at a small-scale milling operation, and see this as a means to
contribute to alleviating micronutrient deficiencies in at-risk populations.
Such field testing will depend on the development of a technology for
effectively blending the premix into a batch of milled grain to be fortified.
MI has taken a number of steps toward meeting this need, and these were
described in Mr. Philar's presentation about the design and testing of
the efficacy of different blending technologies. These technologies are
now ready to be field tested.
For
any intervention or field trial, it was stressed that clear objectives
are essential. The purpose of the fortification effort should be clear
(i.e., is it for the treatment of disease or to improve nutrition), and
specialized training is likely to be needed. Issues to be addressed when
designing and carrying out trials to test the feasibility of fortifying
grains at small scale milling operations were identified. These included:
acceptability by the millers and consumers, selection of fortificants
and their form, who controls what is added, what technology is required,
what training is required, what is the target population, and how to demonstrate
efficacy of the intervention.
There
is interest on the part of Canadian NGOs to be part of this field testing
initiative. Some work is to be done in the North, some in developing countries.
It was agreed that it would be advantageous to continue to exchange information
and establish a network of groups involved in field testing.
