Abstract

The effect of alginate-based edible coating as carrier of antibrowning agents (ascorbic and citric acid) on color, bioactive compounds content and antioxidant activity of fresh-cut mangoes 'Kent' stored at 4 °C were evaluated. The application of alginate edible coating in conjunction with antibrowning agents (ascorbic and citric acid) to mango cubes maintained higher color values (L and °Hue) and increased vitamin C content compared to mango cubes treated only with alginate coating or control. Total phenols content, measured throughout the Folin-Ciocalteu method, was increased 2-fold in cubes coated with alginate plus antibrowning agent. This behavior was attributed to vitamin C addition and not to a real increase in phenolic compounds. However, mangoes coated with alginate plus antioxidant presented higher concentration of ρ-hydroxybenzoic and ellagic acid than those samples coated just only with alginate or control. Mango cubes with antibrowning agents had the highest antioxidant activity due the ascorbic acid addition. The combination of alginate and antibrowning agent preserved the color of fresh-cut mangoes and increased the antioxidant potential of cubes.
