Study of the nutritional quality and acceptability of millet biscuits (Pennissetum glaucum L.) supplemented with cowpea (Vigna unguiculata L) and Bambara groundnut (Vigna subterranea L.) (Published)
The aim of the study was to determine the effect of supplementation of legume flour cowpea and Bambara groundnut from Burkina Faso at different levels 15%, 30% et 50% on the nutritional quality and acceptability of millet biscuits. The macronutrients, iron and zinc contents were determined using standard AOAC methods. The acceptability test of cookies were performed with a panel of 30 tasters. The protein content of cookies increased proportionally with the supplementation. The protein contents of cowpea cookies were higher than Bambara groundnut cookies, 12.82 g / 100 g and 10.47 g / 100 g respectively. Supplemented cookies have low iron and zinc contents, 2.23 mg / 100 g and 1.87 mg / 100 g respectively for cowpea and Bambara groundnut. On the organoleptic level, up to 15% supplementation, there is no significant difference in odor and taste.
