Improvement of Postharvest Quality and Bioactive Compounds Content of Persimmon Fruits after Hydrocolloid-Based Edible Coating Application

Persimmon fruits are often affected by large postharvest losses due to rapid ripening and the early onset of senescence. To reduce such losses in fresh fruits, the application of hydrocolloid-based edible coatings was conducted. Therefore, a plant hydrocolloid-based gum, tragacanth gum (TCG), was ap...

Description
Summary:Persimmon fruits are often affected by large postharvest losses due to rapid ripening and the early onset of senescence. To reduce such losses in fresh fruits, the application of hydrocolloid-based edible coatings was conducted. Therefore, a plant hydrocolloid-based gum, tragacanth gum (TCG), was applied to persimmon fruits at 0.5%, 1%, and 1.5% TCG concentrations, and stored at 20 ± 2 °C and 80–85% relative humidity for 20 days (analysis at 0, 4th, 8th, 12th, 16th, and 20th day). As a result of TCG application on persimmon fruits, there were greatly suppressed respiration rates, ethylene production, weight loss, decay incidence, and H2O2 and malondialdehyde content. In addition, TCG-coated persimmon fruits had higher concentrations of bioactive compounds including phenols, flavonoids, carotenoids, ascorbic acid, and soluble tannin. Higher enzymatic antioxidant activities and lower softening enzyme activities were also recorded for TCG-coated persimmon fruits. Uncoated persimmon fruits quickly lost fruit quality attributes like color, firmness, taste, and aroma during storage compared to coated ones. Based on our findings, the use of TCG, especially at the concentration of 1% TCG, can be recommended to be applied as the edible coating to maintain the nutritional, biochemical, and commercial quality of persimmon fruits during ambient storage.
