ABSTRACT
Gabirobeira fruits are known for their rich nutrient content and bioactive phytochemical compounds that contribute to significant biological activities. Despite these attributes, the antioxidant potential and stability of phenolic compounds in gabiroba by-products after digestion have yet to be studied. The objective of this work was to evaluate the physical-chemical composition, antibacterial activity, α-amylase, and α-glucosidase inhibitory effects, as well as the in vitro digestibility of total phenolic compounds, total flavonoids, and antioxidant activity of powder and extract from gabiroba to valorize these byproducts. The gabiroba powder had low moisture, high carbohydrate and fiber content. The extraction using 80% ethanol demonstrated higher antioxidant, antibacterial, α-amylase, and α-glucosidase inhibition activities compared to the 12% ethanol and water extracts. Catechin and ferulic acid were the major phenolic compounds identified by HPLC-DAD. After digestion, both the powder and the gabiroba extract exhibited a bioaccessibility of more than 30% for total phenolic compounds and antioxidant activity during the gastric phase. However, the dry ethanol extract displayed higher total phenolic compounds after both the gastric and intestinal phases compared to the flour. Processing gabiroba into powder and extract is a promising approach to fully utilize this seasonal fruit, minimize waste, concentrate health-beneficial compounds, and valorize a by-product for use as a functional ingredient and raw material within the food and pharmaceutical industries.
