Abstract: (153 Views)
Persimmon is an important horticultural crop with high perishability and a very short postharvest life that undergoes prompt ripening due to ethylene production and accelerated respiration. Loss of firmness makes persimmon fruits vulnerable to mechanical damage and rot, ultimately restricting long-distance shipping. Thus, providing useful solutions to increase the shelf life of the fruit is very important for natural ingredients. Relating to the beneficial effects of edible coatings, this experiment was carried out as a factorial experiment in a completely randomized design with two factors: melatonin coated with chitosan nanocomposite (0.2% w/v), chitosan (0.2% w/v) and melatonin (100 µm), and control (distilled water) and storage time factor (15, 30, and 45 days). Fruit was treated with storage at 1ºC and 85-90% relative humidity for 45 days. The obtained results illustrated that applying melatonin coated with chitosan nanocomposite treatment significantly caused the maintenance of firmness during cold storage. In addition, the highest levels of total phenols (2966.6 mg/kg FW), total flavonoids (576.6 mg/kg FW), ascorbic acid (17.8 mg/100 g FW), and PAL activity (21.9 U/mg FW) were observed in melatonin coated with chitosan nanocomposite treatment. In conclusion, applying melatonin coated with chitosan nanocomposite as some safe and natural coatings to preserve the quality properties and increase the shelf life of persimmon fruit during cold storage.
