Abstract

Malnutrition is one of the causes of triple burden on the nation. It is decreasing in South Asian countries but still almost 83 million are suffering1. To combat the condition of malnutrition, bio-fortified crops are being developed. One of the crops which were developed is quality protein maize; maize with better biological value and balanced amino acid profile which helped in increasing the absorption of other vitamin A, calcium and carbohydrate 2. In this background, the present study was planned with an objective to develop biscuits with optimum sensory and nutritional attributes which can help in impeding malnutrition. The biscuits were subjected to organoleptic evaluation by the panel of 10 semi-trained judges. A 9- point hedonic scale was used for evaluating sensory attributes of the developed biscuits. There was insignificant difference between overall acceptability score of the developed biscuits but was highest for the biscuits developed from quality protein maize. The quality protein maize containing biscuits had high protein (8.11 g/100 g), ash (1.46 g/100 g), lysine (3.66 g/100 g protein), methionine (1.66 g/100 g protein), tryptophan (0.84 g/100 g protein), linoleic (25.57%), linolenic acid (1.66%) and in vitro protein (81.92%) and starch digestibility (53.18%) acceptability in comparison to wheat biscuits. Thus, incorporation of quality protein maize in the development of bakery products helped in improving the nutrient contents and thus is a good alternative to be used during feeding trial.
