This study was conducted on European grape Vitis Vinifera L. Var.
Helwani, for grape vine in full bearing. Fruit were picked, during two harvest
dates and for three treatments (pre-cooling directly- pre-cooling after 12 h and
without pre-cooling).
A 1×1×1 m pre-cooling chamber was designed (cooling
efficiency 125 kg\ m3) based on iced water and pumped stream air. In addition
to that, we used boxes. Then handled fruit were transferred to the storage units
at 0±1Cо and 90-95% RH for two months. The initial and monthly
measurements for weight loss%, decay%, ripening indicator, firmness kg/cm2
and total soluble solids TSS % were done. The study showed significant effect
of directly application of pre-cooling treatment on decreasing weight loss
0.508% and decay 0.591%.
