Abstract

Grapes (Vitis vinifera L.) is a sub-tropical fruit crop, rich in beneficial anti-oxidants, vitamins, minerals and micronutrients. As grapes are highly perishable, the postharvest management plays an essential role in increasing the shelf life. Hence, research was taken up by keeping grapes under cold and ambient storage conditions during 2022-23. The freshly harvested grapes Vitis vinifera var. Muscat Hamburg was treated with EFF (0%, 2.5%, 5.0%, 7.5%, 10.0%) for 10 mins and stored under ambient (28°C±2°C, RH 60±10%) and cold storage (12°C±2°C, RH 90±5%) conditions and the physiological characters were evaluated. The EFF at 2.5% concentration recorded the minimum physiological loss in weight (1.31%), higher firmness (3.28 N) with increased shelf life of 21 days at cold storage, while nine days shelf life under ambient storage condition. The EFF treated fruits had low TSS (18.1°Brix), indicating improved fruit quality during cold storage as against TSS of 19.3°Brix at ambient storage. Overall, the results clearly indicates that the EFF treated and shrink wrapped grape var. Muscat Hamburg showed delay in ripening process and had an extended shelf-life.

Conclusion

On the basis of this research findings, it can be concluded that EFF treatment has very good effect in extending shelf-life of grapes Vitis vinifera var. Muscat Hamburg. Treatment of grape bunches by EFF dip (2.5%), followed by shrink wrapping is found effective for increasing the shelf life with the minimum physiological loss in weight, TSS and with the maximum fruit firmness of grape berries.
