Abstract:
The present research entitled “Studied on effect of different surface coatings on shelf life and quality of Guava (Psidium guajava L.) Cv. Arkakiran” was carried out during 2020-21 at PG Laboratory, College of Horticulture, Rajendranagar, SKLTSHU, Hyderabad, Telangana. The experiment was laid in completely randomized block design with 7 treatments 3 replications viz., T_1- Aloe vera gel @ 25%, T₂- Aloe vera gel @50%, T₃-Chitosan @0.5%, T₄-Chitosan @1%, T₅-Bee wax @1%, T₆-Bee wax @2%, T₇- control (uncoated) in three replications. The results pertaining to physical parameters Chitosan @1% recorded significantly minimum physiological loss in weight during storage, and least decay percentage, highest shelf life (9.94 days), highest firmness, minimum TSS, highest ascorbic acid, minimum amount of total sugars, reducing sugars and non-reducing sugars which was followed by T₂- Aloe vera @ 50% while least was recorded in T₇-Control. Highest benefit cost ratio was observed in T₄-Chitosan @1% (1.60) which was followed by T₂- Aloe vera@ 50% (1.55) and T₃-Chitosan @0.5% (1.50) while lowest was recorded in T₇-Control (0.80) was observed upto 10 days of storage.
