Evaluation of nutritional quality of Soybean-Acha composite biscuits

Abstract

Biscuits were prepared from

acha -soybean composite flour (85.15) based on preliminary works. The nutritional qualities of the products (biscuits) were evaluated using Wistar-strain albino rat Feed intake, Weight gain, Feed Efficiency Ratio (FER), Protein Efficiency Ratio (PER) and proximate composition of the faeces. The feed intake and weight gain of the acha  soybean composite biscuits and the acha  biscuits (control) ranged from 87.69 91.14g and 5.39 -10.29g, 79.31 91.88g and 8.33 15.48g respectively with increase in duration of feeding (1-4 weeks) and decreased in the 5 thweek. The acha-soybean and acha  biscuits fed rats had feed efficiency and protein efficiency ratios of 0.154 and 0.996; 0.151 and 0.985 respectively. The protein and moisture contents of the feaces collected from animal fed with acha soyabean and acha biscuit ranged from 30.97-31.97% and 9.20- 9.62%, 20.69-23.00% and 7.86-9.42% respectively with increase in duration of feed (1-5 weeks). Higher percentage of fats (2.60- 2.78%) was observed in the soybean blend biscuits. There was no significant effect (p<0.05) in terms of nutrient improvement on addition of soybean, which could have been due to the presence of antinutrient compound inherent in soybean
