Abstract

The aim of the present study was to investigate the postharvest quality of atemoya fruits (Annona cherimola M. x Annona squamosa L.) keeping under different packaging materials in refrigerated conditions. Fruits were treated with 1000 ppm of ethrel at 25°C for three days and packaging by 1) individually sealed in a low-density polyethylene bag (LDPE), 2) wrapped polyvinylchloride (PVC) film, and 3) unpacked as the control, and then stored at 5°C for eleven days. Data of ripening days, weight loss, fruit firmness, total soluble solids (TSS), titratable acidity (TA), peel and flesh color, chilling injury index, and browning index were recorded at the ripening stage. Both packaged fruits had 13 days of postharvest life, and higher fruit firmness. The least fresh weight loss during storage is showed by PVC film. There were no significant differences in TSS, TA, and peel and flesh color among all treatments; however, the LDPE and PVC packed fruits showed the least levels of chilling injury and browning, as well.

Keywords: Annona fruit, modified atmosphere packing, fruit quality.
