Abstract
Flame seedless grapes (Vitis vinifera) were coated with edible films. The samples were divided to three groups. The first group was coated with 1% Carboxy methyl cellulose, the second groups were coated with 1% Carboxy methyl cellulose,0.2% citric acid and 0.1% ascorbic acid. The third group was the control (without coating). All treatments were then stored at room temperature(28±3ºC) for 12days or at cool temperature(4±1ºC) for 90 days. Shelf-life sensory traits including taste, color, texture, and overall acceptability were in control T0 was 9.7,9.5,9.0 for 0,4,8 day stored at room temperature(28±3ºC) with treatment T1 was 9.7,9.5,9.1, 8.9 after 0,4,8,12 day stored at room temperature (28±3ºC), and the sample control were 9.7,9.5, 9.0 after 0, 15, 30 day stored at refrigerator temperature (4±1ºC) with treatment T2 were 9.8,9.5,9.2,8.9,8.7,8.5after 90 day stored at refrigerator temperature (4±1ºC). Also the better sensory acceptance was detected for the treated samples along the storage period. Moisture content significant reduction in moisture was detected in untreated samples compared to treated, moisture decreased during the storage period, as it reached in the sample control (80.06–73.78) after 4 day stored at room temperature and the treatment T1(79.73-75.84) After 12 days from the storage at the temperature of the room. And the treatment T0 (80.22-76.01) after 15 days from the storage at cold temperature comparison with the treatment T1 were (80.1- 76.28) after 90 days from the storage at refrigerator temperature. color, thickness and microbial examination were determined during coating with carboxy methyl cellulose displayed greater external adequacy than untreated ones.
