Abstract

This study evaluated the effects of coatings with juá mucilage (JM), juá mucilage incorporated with phenolic extract from juá (JMPE), and juá mucilage with gum arabic (JM-GA) on quality parameters, bioactive compounds and antioxidant activity of fresh-cut pineapple during 9 days at 5 ± 1 °C. JM and JMPE coatings were effective in reducing enzymatic activity, consequently reducing changes in fruit color compared to uncoated fresh-cut pineapple (C). JM coating was more efficient in reducing metabolic activity with the lowest conversion of sugars into glucose, fructose and organic acids. In addition, JMPE coating showed the highest retention of phenolics. On the other hand, JM had a minor reduction in antioxidant activity in FRAP (39.55 %) and ORAC (33.46 %) assay compared to other coatings (p ≤ 0.05). Findings indicate that JM and JMPE are promising for application to preserve the overall quality and to extend the shelf life of fresh-cut pineapple.
