Functional and sensory properties of cookies prepared from wheat flour supplemented with cassava and water chestnut flours.

Functional and sensory properties of cookies prepared by supplementing different proportions of cassava flour (CF) and water chestnut flour (WCF) blends (0-100%) to wheat flour (WF) were studied. Seven formulations of cookies were prepared from (a) Control (100% WF), (b) 30% WF, 35% WCF and 35% CF, (c) 27% WF, 37.5% WCF and 37.5% CF, (d) 20% WF, 40% WCF and 40% CF, (e) 15% WF, 42.5% WCF and 42.5% CF, (f) 10% WF, 45% WCF and 45% CF, and (g) 0% WF, 50% WCF and 50% CF. Cookies were subjected to physical analysis (cookie diameter, cookie thickness, spread ratio, bulk volume, bulk density, breaking strength, and color analysis) and evaluated for consumer acceptance by descriptive sensory analysis. Cookies prepared from water chestnut and cassava flour had low moisture content (5.63%), low fat (24.87%), higher spread ratio (8.148), decreased L, a and b values (dark color), and low breaking strength than control ones. Sensory evaluation established that cookies prepared from 50% WCF and 50% CF were more acceptable than cookies prepared from other formulations. [ABSTRACT FROM AUTHOR]
