Formulation Optimization of Cookies from Different Levels of All-Purpose,Soybean (Glycine max (L)Merr) and Nami (Dioscorea hispida Dennst) Flour

Ma. Carisse M. Compendio, Lorina A. Galvez


Cookies can be considered as a nutrition-vehicle for children since it can be a good source of higher nutrients and more functional foodproperty needed by them. This study was conducted to optimize the formulation of cookies from different level so fall-purpose,soybean and nami flour. nami was subjected first for detoxification process. A 2, 3 Simplex Lattice Design was used in thi sresearch with all-purpose,soybean and nami flour as the independent variables. Sensory evaluation of the ten treatments was done using Incomplete BlockDesign. Thedata were subjected to optimization study and verified. The optimum treatment was subjected to consumer preference test and proximate analysis. Results of the detoxification process revealed that namiflour is safe to be used for cookies production due to absence of alkaloid. Results of the sensory acceptability revealed that cookies was significantly affected by varying levels of all-purpose flour, soybean and nami flour. The optimum formulation of the cookie product has a level of 25.89 w/w all- purpose flour, 31.25% w/w soybean flour and 42.86% w/w nami flour at the cost of Php 6.20/30 grams cookies. Verification study revealed that the model equations generated were reliable in predicting all of the attributes except aroma. Consumer preference test showed that the optimum product can compete in the market with the existing commercial counterpart product. The optimum cookie formulation has 8.47% crude protein, 0.27% fiber, 19.83% fat , 1.08% ash, 94.11% dry matter and 5.90% moisture content.
