Abstract
The objective of this study was to evaluate the post-harvest shelf-life of 'Golden' papaya fruits submitted to biodegradable coatings based on potato starch, associated or not with lemon grass essential oil under different storage conditions. The experiment was conducted in a completely randomized design with two factorial schemes, where the first one was 3x6, corresponding to three coating techniques: control (T1: no coating), 2% potato starch (T2), potato starch at 2 (T3) and six evaluation periods (0, 4, 8, 12, 16 and 20 days), stored under refrigeration (10 ± 2°C for 12 days and then transferred to the condition 25 ± 2°C for an additional 8 days). In the second experiment, the 3x4 factorial scheme, represented by three coating techniques: (T1), (T2) and (T3) and four evaluation periods (0, 4, 8 and 12 days) stored in ambient condition 25 ± 2°C), with three replicates of two fruits per plot. The potato starch (T3) coating associated with lemon grass essential oil and refrigeration, controlled ripening and further enhanced its efficiency in the control of anthracnose.
