Application of biodegradable coatings on ‘Tommy Atkins’ mango for export
Abstract This study evaluates the effect of a low-cost biodegradable coating formulated with potato starch, rice starch, cassava starch, and gelatin on the postharvest quality of ‘Tommy Atkins’ mango. The experimental design was completely randomized, arranged in a 7x6 factorial scheme with four replications per treatment. The data were subjected to analysis of variance using the Tukey test at 5% probability. After coating, the fruits were stored under ambient conditions (25 ± 3 ºC and 65 ± 5% RH) for 10 days, with analysis every two days. The variables analyzed were: fruit firmness, weight loss, total soluble solids, total titratable acidity, total soluble solids/titratable acidity ratio, delta absorbance (DA) index, colorimetric analysis of the peel and pulp, and ascorbic acid content. The application of biodegradable coatings did not extend the shelf life of ‘Tommy Atkins’ mango during storage.
