Sensory acceptability of cassava snacks nutritionally enriched on Moringa oleifera leaf powder among children from low-income households in Madagascar

Abstract : Ninety two percent of Malagasy population lives with less than two dollars per day. This situation contributes to undernourishment, particularly among children from low-income households: 48% of children under the age of five have stunting problem. Yet, Madagascar possesses natural food resources with high nutritional value, like leaves of Moringa oleifera (M.o.), rich on protein and different oligoelements. These natural food resources should be valorised by incorporating them into children diet, in order to help improving the balance of the diet and thus fight against malnutrition. In this study, M.o. leaf powder was added to cassava roots, which are consumed as a “security food”, during lean period, when the harvests are exhausted and the price of food products increase. The obtained product was a snack targeted to schooled children. The objective was to determine if children would accept this new product. Four formulations were made: cassava alone, cassava with 0.6% of M.o., cassava with 0.6% of M.o. and 10% of sugar, and cassava with 1.2% of M.o. and 10% of sugar. Two hundreds and twenty four schooled children, balanced over four locations (urban and rural areas of two regions: Antananarivo, where M.o. is not known by the population, and Antsiranana, where M.o. is known and consumed by the population), measured the acceptability of the snacks. The measure was made by using facial 7-points scale (1: disliked extremely, 4: nor disliked nor liked, 7: liked extremely). Results showed that the level of acceptability of M.o. by the children depended on region: cassava enriched by M.o. was better accepted in both Antsiranana rural and urban (acceptance score = 4.24-6.64), than in Antananarivo, where it was slightly disliked (acceptance score = 3.5 and 3.77 respectively in urban and rural area) when no sugar was added. Knowing that the snacks enriched on M.o. were accepted and liked by the children, and that they increased the protein and oligoelements intake, this study can help to formulate products with higher concentration of M.o., in order to improve the nutritional status of Malagasy children from low-income households.
