Moisture diffusivity of grapestems was studied under cold airflow storage conditions (1.21±0.25°C and 1.18±0.23ms-1) during postharvest storage. The stems were stored without packaging liner films or with packaging liners (packed in non-perforated liner films) under low temperature conditions inside cold room. Effective moisture diffusivity values for stem parts packed in non-perforated liner films were lower than the values obtained for stem parts stored without packaging liners, and varied from 5.06×10-14-1.05×10-13m2s-1. Dehydration rate of stem parts directly exposed (without liners) to circulating cold air was significantly (P<0.05) higher than the dehydration rates of stem parts packed in non-perforated liner film. Empirical models were applied to describe the dehydration kinetics of the different parts of stem.
