Consistent effect of Nile tilapia (Oreochromis niloticus) fortification in biscuit on nutritional composition, consumer perception and shelf life properties

Fish can be regarded as a promising protein ingredient for food fortification and enrichment. This study aimed to investigate the potential application of Nile tilapia fish as a dietary supplement. Fish powder was fortified in 0 (control), 5, 10 and 15% levels in dry ingredients by replacing wheat flour and other ingredients were kept constant. Then, biscuits were prepared and the proximate composition, physical and texture properties were determined, as well as sensory acceptance. The...
