Effect of Pumpkin Flour on the Rheological Characteristics of Wheat Flour and on Biscuit Quality

Abstract

Effect of pumpkin flour on the physico-chemical, rheological, nutritional and sensory characteristics on biscuits was studied by incorporating pumpkin flour at different concentrations from 5-25% based on refined wheat flour (Maida). Addition of 15% of pumpkin flour was found to be optimum for biscuit preparation. Effect of incorporation of pumpkin flour had a significant (p ≤ 0.05) effect on rheological characteristics of wheat flour studied by using mixograph, alevo-consistograph and rapid visco analyser etc. During storage, the chemical changes and overall acceptability scores were found to be negatively correlated (r<-0.97).
