Development of Reconstitutable Yam /Cassava Flour Blends Enriched with Soy Flour for Pounded Yam Preparation
Yam flour was mixed with cassava starch (25% w/w). The firmed yam flour was then fortified with soybean at 0–30% levels. The nutritional composition, functional and sensory properties of the complementary blends was analyzed. The results showed significant increases (p<0.05) in protein from 10% for yam flour/ cassava starch without soybean flour to 58% for yam flour/ cassava starch fortified with 30% soybean flour. Fat content increased from 4.6% to 70.9% for samples fortified at 0% and 30% soybean flour addition. However, carbohydrate decreased significantly (p<0.05) from 77.5% to 59.9% with increased soybean flour substitution. The micronutrient composition showed that chromium, cadmium, lead and zinc were absent while iron and calcium were trace. There was significant increases (p<0.05) in amount of potassium, magnesium and phosphorus with increased soybean addition. Sensory analysis showed that panelists accepted the blends up to 30% soybean flour addition.
