Abstract

The present study aimed to know the influence of ozonated water on post harvest attributes in grapes cv. Muscat Hamburg during 2023-2024. The study involved treatments of 0.3 ppm of ozonated water at different minutes viz., 3, 6, 9 and 12 min. The harvested berries were immersed in the ozonated water and air dried before storage. Observations were recorded on titratable acidity, total phenols, physiological loss in weight, shelf life and rachis dehydration. Significant differences were observed among the control and treated berries. The titratable acidity (0.34 & 0.29), total phenols (119.55 & 107.38), physiological loss in weight (10.1 & 7.52), shelf life (29.25 & 34.50) and rachis dehydration (2.8 & 3.0) were observed during season (1 & 2) and indicating the possibility of improving post harvest attributes and life of grapes berries.

Conclusion

In the present study, the treatment of grape bunches with ozonated water for 12 minutes (T5) was the most effective postharvest treatment in preserving the quality and improving the shelf life of fruits. Thus, ozonated water has got multifaceted applications which can ensure pesticide residue free fruits with better quality and shelf life.
