Abstract:
The present investigation entitled “Effect of edible coatings on shelf life of Apple ber (Ziziphus mauritiana L.) under ambient storage conditions” was carried out at College of Horticulture, SKLTSHU, Rajendranagar, Hyderabad during the year 2021-2022. In an attempt to achieve the objective of effect of edible coatings on shelf life of Apple ber (Ziziphus mauritiana L.). The experiment was conducted in Completely Randomized Design in four replications with five treatments consisting of three edible coatings viz. T₁: Aloe vera gel @ 2%, T₂: Chitosan @ 1%, T₃: Guar gum @ 2%, T₄: Garlic extract @ 10% and T₅: Control (without edible coating) in four replications, stored at ambient temperature. The fruits used in all the treatments are stored at ambient conditions and the physical parameters are analyzed daily. Fruits treated with Guar gum @ 2% recorded significantly lowest PLW (13.86%), spoilage (45.72%), and browning score (4.55) and significantly highest fruit firmness (9.51 kg/cm²), surface colour (1.06) on 12^th day, at the end of storage. The highest shelf life (13.08 days) was also seen in fruits treated with Guar gum @ 2% followed by Chitosan @ 1% (12.21 days).
