The present study had been conducted to study the shelf life of grapes with coatings of Aloe Vera suspended in water with concentrations of 0, 10, 20 and 30 per cent Aloe veraand was stored in poly packaging and open plates under different temperatures of 0⁰C and 30⁰C in refrigerator and incubator. The data was compared with the original shelf life of grapes to determine the efficiency of the Aloe Vera coating. Aloe Vera based coatings provided good gloss and 20 per cent coating concentration gave the best visual and physicochemical results. It was found that 20 per cent coating concentration of Aloe Vera is the most effective and appropriate for the extension of shelf life of grapes.It was also found that the use of low temperature storage in combination with edible coating and packaging extends marketability by reducing moisture loss.In short, the shelf life of grapes can be increased by using Aloe Vera gel coating and the spoilage due to fungal infection of grapes can be reduced.
