Abstract
Banana is one of the most consumed fruits in the world due to its pleasant sensory characteristics and nutritional composition. After consumption of the pulp, large amounts of peels are generated which, after dehydration and flour transformation, can be inserted into cake formulations. In this sense, the objective of this work was to evaluate the influence of D'Angola banana peel flour and sugar concentrations on the physical and chemical characteristics of cakes. These were processed by experimental factorial design 22 with 3 repetitions at the central point, resulting in 7 experiments. A mixture composed of wheat flour, yeast, butter, whole milk and eggs was prepared, with subsequent addition of different levels of banana peel flour and crystal sugar. After cooking for 28 min at 200 °C and cooling, the cakes were subjected to chemical and physical analysis. The mathematical models adjusted to the experimental data of SST, ATT, pH and SST/ATT ratio were observed to be significant and predictive, with correlation coefficients greater than 0.98 and Fcalculated/Ftabulated ratio greater than 4.0. TSS was significantly influenced only by sugar, which was also the independent variable that most affected the TSS/TTA ratio. On the other hand, the banana peel flour factor had a major influence on the ATT and pH results.
