Impact of Green Pulp Banana and Flaxseed Flour on Pound Cake Quality

The study investigated the combined effects of different levels of green pulp banana and flaxseed flour on the technological properties of pound cake. The effect of these ingredients was observed on the physical properties of the pound cakes (specific volume, symmetry, moisture and weight loss). The data were evaluated by response surface and the optimized formulation was evaluated, along with the control, through sensorial analysis, proximate composition and crumb porosity. A significant influence of the ingredients on the specific volume was observed, leading to their reduction. There was influence of green pulp banana on moisture and weight loss. In this way, the optimized formulation was established with 11.5% of green pulp banana and 5% of flaxseed flour. The optimized formulation had a higher content of protein, ash and fat and lower carbohydrate content than the control formulation. In addition, there were no significant differences between the sensorial attributes evaluated, with texture exception.
