Abstract
This experiment was conducted to investigate the influence of packing of local lemon (Citrus lemon L.). The study was included the control treatment, seal packing with cellophane film (35 mm. in thickness) wrapping with paper treatment with pavisten at a rate of 2cc/Treated, packing in a low density polyethylene film (60 mm. in thickness) with 16 holes/kg fruit 0.5 cm diameter and waxing with vegetable oil at 2% concentration. Fruits were stored at 5 ± 1 ºC and 75-85% RH. CRD was adapted with three replicates, 2 kg per replicate. The results showed that the treatment with oil at 2% concentration gave the lowest percent of weight loss (1.27%) while the highest percent (2.99%) was in the control treatment. Weight loss was increased by increasing storage period. TSS was increased by increasing storage period, while there was no significant effect of the treatments in this parameter. Increasing storage period decreased the percent of juice while treating the fruits with 2% oil gave the highest percent of juice (45.10%). Vit. C content was decreased by increasing storage period and the highest content of 38.74 mg/100ml juice was recorded when fruits treated with 2% oil. No physiological disorder were noticed when fruits were treated with 2% oil and seal packing of fruits and when fruits packed in polyethylene, while packing fruits with paper treated with pavisten reduced the physiological disorder by 75%. The decay percent was the lowest in fruit packed with paper treated with pavisten followed by fruits treated with 2% oil and the seal package, while the control treatment gave 1.91%. The highest percentage of acidity 8.47% was noticed in fruits trented with the oil followed by 8.41% in the seal packaged fruts, while the lowest percentage of 7.73% in the control treatment.
