Effects of blending ratios and baking temperature on physicochemical properties and sensory acceptability of biscuits prepared from pumpkin, common bean, and wheat composite flour

The utilization of vegetables with supplementation of cereals and pulses plays a vital role in improving protein -energy malnutrition and micronutrient deficiency. Therefore, the study aimed to develop biscuits from pumpkin, common bean, and wheat composite flour with better physicochemical properties and sensory acceptability. All quality parameters were evaluated by using an official standard procedure. The results showed a significant (p < 0.05) difference among products. The addition of pumpkin and common bean flour to composite biscuits significantly (p < 0.05) increased the protein (9.44-16.16%), fat (17.03-21.42%), ash (1.72-2.08%), and crude fibre (1.37-2.06%) contents. In addition, the biscuit's lightness decreased as the incorporation of pumpkin and common bean increased. However, the redness and yellowness of the sample increased. Sensory evaluation scores indicated that biscuits supplemented with 10% pumpkin, 15% common bean, and 75% wheat composite flour baked at 200 degrees C were more preferred than other formulated products. Therefore, substituting pumpkin powder with wheat-common bean flour significantly improved the nutritional content of the biscuit with desirable sen-sory acceptability. The findings also showed that the developed products are essential in improving dietary di-versity and food insecurity among low-income families.
