Development and characterization of cookies using passion fruit from the caatinga (Passiflora cincinnata Mast.)

Abstract

The objective of this study was to use the passion fruit peel P. cincinnata Mast., as a viable alternative to produce food (flour and cookies) that is rich in fiber and environmentally sustainable. For this, fruit peels were obtained, which were hygienized, dehydrated and ground in a knife mill in order to develop the flour, which was then used in different concentrations in three formulations of chip cookies (using 10%, 20% and 30% of the flour developed). Analyzes physicochemical and microbiological composition were performed for both flour and for the cookies developed and a sensorial acceptance test was performed for the cookies. It was possible to observe that the flour had an adequate centesimal composition, when it was about quality and safety, as well as health benefits. As for the physicochemical composition, the flour had 5.79 ± 0.11% of ashes; 78.23 ± 0.84% of total carbohydrates; 5.78 ± 0.11% moisture; 4.83 ± 0.00% acidity; 3.74 ± 0.04 pH; 1.66 ± 0.06% lipids; 8.59 ± 0.82% protein and 58,3 g/100g dietary fiber. The study demonstrates its nutritional quality by reducing the lipid content of the final product, by comparing the formulation with 30% of the flour developed to the standard formulation, as well as increasing the ash content and acidity and reducing its pH when compared to the standard formulation, promoting the safety and quality of food. Flour presented promising capacity in the development of functional foods, health promoters, and environmental conservation by avoiding its inappropriate disposal.
