Nutritional evaluation and consumer preference of legume fortified maize-meal porridge
MetadataShow full item record
Maize-meal porridge is commonly consumed meal for the adults as breakfast food and for the children as complementary food. Food-to-food fortification was employed in order to improve the protein content of maizemeal porridge using soy flour and local groundnut paste. The study was aimed at evaluating the nutritional properties and consumer preference of the attributes of the unfortified porridge, legume-fortified porridge, and powdered milkfortified porridge. The influence of consumers’ knowledge of the type of fortificant added to the porridge was also investigated. Soy-fortified porridges provide comparable ash, crude fibre and fat contents to powdered milk- fortified porridge but with higher protein than powdered milk-fortified porridge. Soy flour raised the protein and ash content of the porridge by 90% and 63% respectively, the groundnut paste raised the protein and ash content by 88% and 41% and the powdered milk by 87% and 65% respectively. The unfortified porridge was the least preferred while the milk-fortified porridge was the most preferred. There was no significant difference between preference for some of the attributes of the groundnut paste fortified-porridge and the soy flour-fortified. There was no significant difference between consumption intent for the soy flour and groundnut paste -fortified porridge. Soy-fortified porridges provide comparable ash, crude fibre and fat contents to powdered milk- fortified porridge but with higher protein than powdered milk-fortified porridge. Soy-flour has shown to be a good substitute for powdered milk as a protein-fortificant for porridge and soy-fortified porridge could be a possible means of alleviating Protein-energy malnutrition among low income populations.
