well come
Horticultural crops specially grape not only provide us with nutritional and healthy foods, but also generate a cash income to growers.
The horticultural crops, because of their high moisture and biochemical activities have more losses on post harvest( related to the crop, up to 60%).
So that Utilizing improved cold chain system during post-harvest practices often results in reduced horticultural crops losses, improved overall quality and food safety, and higher profits for growers and marketers.

Importance of cold chain
Maintenance of the cold chain is the best way to maintain the quality of a product and minimize all forms of deterioration after harvesting, including:
Weight loss resulting in wilting and limpness.Softening.Unwanted ripening.Color changes.Texture degradation.Development of rot and molds.
