Abstract
BACKGROUND: Micronutrient deficiencies continue to afflict children rural populations around the world. A micronutrient
delivery vehicle (MDV) was developed as a point-of-use technology for fortification of meals for school-age children beneficiaries
of the Healthy Schools Program (HSP) in Honduras.
RESULTS: MDV combines micronutrient powder through a traditional dough-making process, using staple flours (wheat and
nixtamalized corn), oil and water as ingredients. After mixing the ingredients and kneading, dough is extruded through a
specially designed hand press into noodles. After drying (overnight, 23
∘
C), noodles are broken into small pieces, mixed (1:100
w/w) with rice and cooked as customary. Dispersion studies with NaFeEDTA showed adequate distribution (<10% RSD) and
recovery (>90%) in white rice. Color changes in MDV due to addition of vitamin A and iron (NaFeEDTA) carried forward into
cooked rice. In Honduras, children from two rural schools (N = 47, 6–12 years) were not able to differentiate (triangle test)
between control and unfortified MDV mixed (1:100 w/w) with white rice. Children from four schools (N = 83, 7 –12 years) accepted
control and iron fortified rice (3 mg Fe per serving) based on color and flavor similarly.
CONCLUSION: This is a feasible point-of-use fortification technology for improvement of meals provided by the HSP in Honduras.

INTRODUCTION
Micronutrient deficiency is one of the most common and pre-
ventable nutritional problems in the world. The World Health
Organization (WHO) has identified iron, iodine and vitamin A (VA)
as critical micronutrients, whose deficiencies are estimated to
affect as many as 2 billion people worldwide, especially women
and children living in rural areas in developing countries.
1,2
Hon-
duras is a low-income country with a population of 7.5 million, 50%
of whom live in rural areas.
3,4
Approximately, 45% of the total pop-
ulation and 60% of the rural population live in extreme poverty.
5
Poverty is the main cause of food insecurity, which reduces access
to a balanced and varied diet, high in critical micronutrients. Ane-
mia, mostly due to iron deficiency, is high in Honduras, affecting
29% of children <5 years and 15% of women 15–49 years.
6
Iron
deficiency anemia in young children impairs physical growth, cog-
nitive development and the immune system. It also affects perfor-
mance in school-age children, which when carried into adulthood,
leads to generalized fatigue and reduced work capacity.
7,8
Sev-
eral strategies have been implemented to prevent and control
micronutrient deficiencies; however, the problem still persists.
9
Mass fortification has been the most efficient, cost-effective
strategy to reduce micronutrient deficiency in industrialized coun-
tries. Nonetheless, staple food fortification programs have not
always yielded the expected results in developing countries. In
rural areas impacts have been staggered for reasons such as
high implementation costs, distribution constraints, poor cultural
acceptance, low coverage, non-compliance with intake of sup-
plements and lack of economic access to processed foods.
10 – 13
In Honduras, government fortification efforts have been directed
at providing vitamin and mineral supplementation through clin-
ics and fortification through staple foods, e.g. sugar (VA), salt
(iodine) and wheat and maize flour (iron).
14
In addition, the Hon-
duran government has made significant efforts to promote chil-
dren’s nutrition through improvement of meals within the Healthy
Schools Program (HSP). The HSP coordinates the distribution of
Government-procured foods from the World Food Program and
other donors, providing one complete meal per school day to
over 1.2 million children, mostly living in rural areas. This meal
consists of rice, beans, corn, vegetable oil and corn soy blend; pro-
viding a total of 570 kcal per child per day.
15
In order to main-
tain and improve impact, the HSP is constantly searching for more
nutritious and economical alternatives to its current offering. For
instance, corn soy blend is one of the first fortified blends used
