Abstract :
Moisture loss characteristics of grapes packed in different packaging liner films during cold storages (1.21 ± 0.25 °C) were studied. The moisture loss rate from grapes packed in non-perforated liner films was significantly (P < 0.05) lower compared to the moisture loss rate from grapes packed in perforated liner films (120 × 2 mm and 36 × 4 mm perforated liner films). After 72 d of cold storage, the maximum moisture loss of grapes stems was significantly (P < 0.05) higher (range from 49.24 ± 4.66% for non-perforated liner films to 88.55 ± 0.61 for no packaging treatment) than moisture loss of grapes berries which was less than 10%. Transpiration coefficients of the different stem parts and grape berries stored in a no packaging treatment decreased significantly (P < 0.05) with storage period. The 36 × 4 mm perforated liner film resulted in a significant (P < 0.05) decrease of transpiration coefficients of the intermediate stem; large stem parts and berries. There were no significant differences between the transpiration coefficients of the bunch parts stored in the 120 × 2 mm and non-perforated liner films. The transpiration rates of stem parts were lowest in the non-perforated liner film compared to other packaging treatment, while the transpiration rates of grape berries showed no differences between the different packaging treatments (0.79 ± 0.51 g kg−1 d−1, for the non-perforated liner film and 1.57 ± 0.58; 1.59 ± 0.75; 1.37 ± 1.00 g kg−1 d−1, for the no packaging; 120 × 2 mm and 36 × 4 mm perforated liner films respectively).
