Addition of green banana biomass as partial substitute for fat and encapsulated Lactobacillus acidophilus in requeij?o cremoso processed cheese

摘要

This study evaluated the effects of the addition of encapsulated Lactobacillus acidophilus and green banana biomass on the characteristics of requeij?o cremoso processed cheese during the storage period of 45 days under refrigeration. The elaborated requeij?es cremosos processed cheeses included addition of encapsulated Lactobacillus acidophilus as probiotic source, and green banana biomass as partial fat substitute, in a total of five treatments. Analyses were performed to evaluate probiotic viability, microbiological conditions, centesimal composition (moisture, fat, fat in dry extract, protein, ashes, carbohydrates), water activity, resistant starch, colour, texture, lipid profile and sensory acceptability. The addition of green banana biomass and fat reduction resulted in changes in the centesimal composition of the cheeses, with their moisture indexes increased and protein decreased, the F1 formulation was the only one that can be considered as low fat content and was also the one that presented higher moisture. The yellowish white coloration of the formulations was altered as a function of the composition as well as the texture parameters, F1 and F3 treatments presented the greatest changes. Probiotic viability did not differ between formulations, it only changed over time.
