Fig. 2. Effect of different concentrations of lemongrass essential oil incorporated into alginate-based edible coating on (A) L value, (B) chroma and (C) hue angle of fresh-cut
pineapple during 16 days of storage at 10 ± 1 ◦ C; 65 ± 10% RH. Means with the same letters (lowercase: amongst different treatments for the same time; uppercase: for the
same treatment during different storage times) are not significantly different according to Tukey’s test (p > 0.05). EC = alginate-based edible coating; Lg = lemongrass.
