Impact of processing and packages on bioactive compounds and antioxidant activity of Mangaba Jelly

Abstract

This study evaluated the impact of processing, packages (amber and transparent glass jars), and storage time on the stability of the bioactive compounds (total phenolic compounds and vitamin C), and antioxidant activity of mangaba jelly. Jelly processing, significantly (p < 0.05) decreased the bioactive compounds and antioxidant activity. The storage time, significantly (p < 0.05) influenced all the variables studied in this work, although they were not affected by packages. A significant decrease of the bioactive compounds and antioxidant activity was observed during the jelly storage. HPLC-DAD/UV-Vis analyses allowed to identify 10 phenolic compounds, including flavonoids and non-flavonoids, and among these, quercetin and catechin were the major compounds. After processing, all these compounds decreased significantly (p < 0.05), except for the gallic acid and the p-coumaric acid, which presented an increasing tendency. During jelly storage, only gallic acid, caffeic acid, catechin, and rutin were affected. Despite the reduction in the antioxidant activity and bioactive compounds studied, mangaba jelly retained good levels of them and may be considered a potential novel functional food.
