There is a growing demand for healthy and functional foods, with probiotics standing out as beneficial components for health. Therefore, this study aimed to evaluate the properties of fermented bocaiuva (Acrocomia aculeata) puree with Lactiplantibacillus plantarum and its stability during simulated digestion and storage for 21 days at -18 degrees C. Probiotic viability, pH, TTA, total soluble solids (TSS), instrumental color, and carbohydrate profile were investigated at 0 h, 24 h, and 48 h. After 48 h, the stability of probiotics and physicochemical parameters were evaluated after simulated digestion and frozen storage. The fermented bocaiuva pulp with L. plantarum showed a significant increase in viable cell count, reaching 9.53 log CFU/mL at final fermentation time (t48h) with a concomitant reduction in pH and an increase in TTA. The glucose and fructose levels decreased with fermentation, as well as the TSS, while an increase in the sorbitol content was observed. Neither fermentation nor freezing significantly affected the color of bocaiuva pulp. Our key findings show that after simulated digestion, L. plantarum had a survival rate of 76 %. In addition, cell viability was maintained during frozen pulp storage, with a high concentration of lactic acid bacteria. We conclude that bocaiuva pulp can be a suitable substrate for the growth of L.plantarum and, consequently, an alternative to increase probiotic intake. It should be noted that these microorganisms remain viable even after freezing and simulated digestion, and the physicochemical parameters are stable. (AU) | |
