KW - Gum arabic KW - Beeswax N1 - Includes bibliographic reference N2 - Extending postharvest fruit life demand cold storage period prolongation with reasonable marketing life. In this scope, quality of Olinda orange was determined in response to arabic gum, bee wax, paraffin oil and chitosan coatings during simulated marketing life at 20°C for 12 days after cold storage at 5°C and 90-95% relative humidity for 90 days. All applied coatings had desirable effects on fruit quality compared with the control, where the best treatment was chitosan at 1 and 2% that were effective in maintaining ascorbic acid content compared to the uncoated ones. Chitosan coating at 2% attained the lowest significant weight loss and decay percentages. Also, it delayed changes associated with fruit aging such as colour changes, softening and pectin the methylesterase activity, in addition to valuable means of respiration rate compared to the uncoated ones. Coatings are easily applied tools that could be suitable for extending Olinda orange postharvest marketing life UR - http://nile.enal.sci.eg/EALE/2017/BFACU/6817/4/425.pdf ER -
