QUALITY EVALUATION OF BISCUIT FROM WHEAT-TIGER NUT COMPOSITE FLOUR

Abstract

The quality evaluation of biscuit from wheat-tiger nut composite flour was carried out. Biscuit was prepared from varying proportion of 100%, 90%, 80%, 70%, and 60% wheat flour substituted with 0%, 10%, 20%, 30% and 40% tiger nut flour respectively. The biscuit samples were analyzed for the chemical composition, physical, sensory and functional properties on the blends. The tiger nut flour addition increased (p<0.05) significantly the moisture content (4.64 – 5.16). Sensory evaluation showed that although there was significant (p<0.05) increase in the nutritional content of the biscuit, the overall acceptability of all biscuit samples decreased with increasing level of tiger nut flour.
