Evaluation of partial replacement of wheat flour with Phaseolus Vulgaris Bean flour in the formulation of cakes

Abstract

The aim of this study was to obtain and characterize red bean flour (Phaseolus vulgaris) INTA Red variety and evaluate its potential use as a partial substitute for wheat flour in the production of cakes.  In the production of bean flour, the operations of selection, washing, soaking, cooking, drying and milling were carried out. Soaking times of 3, 6 and 12 hours were used. Then, the bean flour was characterized and the cakes were prepared with the four levels of inclusion (0, 10, 20 and 30 %).  In the results of the experiments it was found that the soaking time of 12 hours allows to reduce the cooking time of the beans. The yield of bean flour was 68.67±0.05 %, the average particles diameter of the flour was 0.2231 millimeters, bulk density 0.714 ± 0.01 g/cm³ for whole flour and 0.697 ± 0.004 g/cm³ for flour without tegument. The water and oil holding capacities were 2.57±0.07 g of water/g of flour and 0.66±0.14 g of oil/g of flour, respectively. From the sensory analysis it was determined that cakes made with 10% inclusion of bean flour are the ones that have the highest acceptance, so it could be suggested as an optimal level of inclusion.
