Use of chemical additives for postharvest conservation of fresh cut 'Apple' Banana

This work had the aim of studying the effect of treatments with ascorbic acid (AA), calcium chloride (CC) and L-cysteine hydrochloride (LC) on the postharvest quality of fresh-cut 'Apple' banana. The following combinations were tested: 1 (Control); 2 (AA 1%); 3 (CC 1%); 4 (LC 0.5%); 5 (AA 1% + CC 1%); 6 (AA 1% + LC 0.5%); 7 (CC 1% + LC 0.5%); 8 (AA 1% + CC 1% + LC 0.5%). The bananas were peeled, sliced and immersed into the treatments, conditioned on trays, which were wrapped with 30 µm PVC film, and stored at 5 ± 1ºC and 90 ± 3% RH, during 4 days. Evaluations occurred at 0, 1, 2 and 4 days. There was an increase in the mass loss during the storage period, lower in the treatment 8 in relation to the others. Total titratable acidity increased linearly throughout the time in all treatments. The loss of firmness was prevented more efficiently in the treatments with calcium chloride. A pinkish-red color formation on the slices treated with L-cysteine was observed and evidenced by the highest values of a*. The L* value and the browning index were also affected by the treatments containing L-cysteine, whose decrease in these color parameters was higher in the untreated slices throughout the time. The treatment of fresh-cut 'Apple' banana with the combination AA 1% + CC 1% + LC 0.5% was efficient for its postharvest quality maintenance.
