Development and evaluation of low-carb cakes produced from green bocaiuva pulp enriched with Pleurotus ostreatus

The aim of this work was to develop and evaluate low-carb cakes by replacing wheat flour with green bocaiuva pulp enriched with Pleurotus ostreatus. Four formulations were tested: F1: coconut flour, F2: green bocaiuva flour, F3: green bocaiuva flour enriched with P. ostreatus and ammonium nitrate and F4: green bocaiuva flour enriched with P. ostreatus. Results indicated that all formulations can be considered as protein source foods (7.33–10.47 g 100 g ⁻¹), with high fiber contents (7.16–9.43 g 100 g ⁻¹), and low-carbohydrate contents (13.92–21.87 g 100 g ⁻¹), without sugar addition. F4 presented the highest scores for all sensory attributes (color: 7.77; aroma: 7.55; texture: 7.32, flavor: 7.18 and overall impression: 7.73) and purchase intention (68% for the sum of probably and certainly would purchase). Thus, the green bocaiuva flour enriched with P. ostreatus can be used for the development of low-carb cake with improved nutritional components and acceptable sensory characteristics.
