The effect of coatings was evaluated on the quality of harton plantain fruits (Musa paradisiaca) in the postharvest stage. Solutions for three treatments were prepared from 50 g L-1 cassava starch (Manihot esculenta) with 30 g L-1 glycerol as the plasticizer and 6 g L-1 polyethylene glycol-600®; for anti-browning agents, 6 g L-1 ascorbic acid (AA) and 8 g L-1 N-Acetyl-Cysteine (NAC) were added.
The fruits were coated by immersion, stored at 18 ± 4°C and 85% RH. Physicochemical properties were determined at 32 days postharvest.
The applied coatings decreased the physiological weight loss (%WL) and resulted in a higher pulp firmness (PF); no significant difference was seen with a confidence level of 95% in the concentration of total soluble solids (TSS), acidi...
