Abstract:
Guava (Psidium guajava L.) is an important fruit crop grown under a wide range of tropical and subtropical regions in the world. The “Study on effect of different organic based products as a post-harvest treatment on shelf life and quality of guava (Psidium guajava L) Cv. lucknow-49” was conducted in Completely Randomized Design in three replications with ten treatments. The main aim of the study was to investigate the effects of different edible coating treatments like Aloe vera gel, Sodium alginate and Guar gum at varying concentrations on physico-chemical characteristics and shelf life of guava fruits. Observations are recorded under each treatment over a storage period of 12 days, after harvesting, starting from harvest day till 12^th day during the winter season. Aloe vera gel (100%) and Guar gum (1.5%) coating was most effective in reducing weight loss, decay, shelf life, chlorophyl degradation, maintaining firmness, total soluble solids, titratable acidity, ascorbic acid, total sugars, reducing sugar, non-reducing sugar, TSS: acid ratio, B:C ratio than other treatments. Hence, it was concluded that dip treatment of 100% Aloe vera gel can be used for enhancing the shelf life and reducing postharvest losses in guava fruits.
