The aim of this study was to investigate the effect of pretreatment with 1-methylcyclopropene (1-MCP) and the application of edible coatings (xanthan, sodium alginate or gellan) on the ripening rate, quality parameters and shelf life of pre-cut jackfruit. The jackfruit bulbs dipped in potassium sorbate/calcium chloride PS/CC (T-1) and PS/CC/1-MCP (T-2) showed a more rapid ripening and greater microbial growth at 7 and 12 days of storage. However, jackfruit bulbs with PS/CC/1-MCP and covered with xanthan, sodium alginate or gellan (T-3, T-4, and T-5, respectively), showed a decrease in the ripening rate; thus weight loss and respiration rate were lower and the higher quality values as colour (degrees Hue), total soluble solids (TSS), titratable acidity (TA) as well as pH were achieved until 12 days of storage. Firmness values were higher in bulbs under T-3, T-4, and T-5 compared to bulbs under T-1 and T-2. Microbial growth was delayed until the 12th day of storage in jackfruit bulbs with T-3, T-4, and T-5. In general, manually peeled jackfruit stored at 5 degrees C and coated with 1-MCP/edible coatings, maintained the quality and sensory acceptability of fresh-cut jackfruit and with a longer shelf life than previously reported.
