These studies were conducted to find the effects of laser ablation OTR film types on MA package in perilla leaf, rape, pak choi and chicory sort of leaf vegetable. They were treated at two different temperature conditions and storage for 7 days, except the rape 25℃ treatment, which was stored for 5 days with four types of laser ablation film such as 3,000 cc, 5,000 cc, 7,000 cc and 10,000 cc/m2·day·atm films for perilla leaf and pak choi, 10,000 cc, 20,000 cc, 30,000 cc and 40,000 cc for rape, as 5,000 cc, 7,000 cc, 10,000 cc and 20,000 cc for chicory. In the all treatments, fresh weight loss rate was lower than 0.8% in 12℃, 1.6% in 25℃ except for the 10,000 cc film of perilla leaf. In the carbon dioxide contents, perilla leaf was maintained at the lowest in 12℃ and 25℃ for 10,000 cc, rape was maintained 3-4% in 30,000 cc and 40,000 cc at 12℃, and more than 6% in all film when finish stored at 25℃, pak choi was maintained about 5% except for the 3,000 cc film in 12℃, and chicory was showed average 3% that slightly higher at 12℃ in the 20,000 cc and increase more than 12% at 25℃ in all treat films. Ethylene content tended to be low with higher gas transmission film, but rape treated with the 10,000 cc and pak choi treated with the 3,000 cc film showed low content than average. It was considered that high carbon dioxide and low oxygen content inhibited ethylene occurrence. Rape was highly damaged by yellowing, but perilla leaf cleared. The 5,000 cc film at 12℃, 7,000 cc film at 25℃ for perilla leaf and the 10,000 cc film at 12, 25℃ for rape and 3,000 cc film at 12, 25℃ for pak choi and the 20,000 cc film at 12℃, 5,000 cc film at 25℃ for chicory had the best visual quality through panel test. In the off-flavor, the 7,000 cc film at 12, 25℃ for perilla leaf and 20,000 cc film at 12, 25℃ for rape and 7,000 cc film at 12℃, the 3,000 cc film at 25℃ for pak choi and 5,000 cc film at 12, 25℃ for chicory showed the best results. The conclusion was 5,000 cc and 10,000 cc films were the best film for MA storage at 12℃ and 25℃ in perilla leaf because it showed the best quality of visual quality and off-flavor. In the case of rape, 12℃ treatment was better than 25℃, and the 10,000 cc film showed the best results in carbon dioxide contents and off-flavor. In pak choi, the 3,000 cc film treatment was better than other films at off-flavor, carbon dioxide and visual quality for 12℃ MA storage, and the 10,000 cc film treatment was better than other films at off-flavor and visual quality. The 20,000 cc firm was the most reasonable treatment in both storage temperatures for chicory.

레이저 가공 OTR 필름이 "신고" 배의 MA 저장성에 미치는 영향

These studies were conducted to identify the effects of laser ablation OTR (oxygen transmission rate) film on storability at 1℃, 8℃, and 20℃ when storing ``Niitaka`` pears. The fresh weight loss rate of pear was less than 1.5% in all OTR films at three different storage periods and temperatures, 1℃; 210 days, 8℃; 180 days, and 20℃; 45 days except for the perforated film. The 10,000 cc and 20,000 cc (1℃), 20,000 cc and 40,000 cc (8℃), and 40,000 cc (20℃) films were closed at the optimum MA storage condition by carbon dioxide and oxygen concentration. Ethylene concentration was lowest at the 1,300 cc and 20,000 cc (1℃), 1,300 cc and 5,000 cc (8℃), and 20,000 cc (20℃) films for each temperatures during storage. The 10,000 cc OTR film showed the highest visual quality at 1℃, the 20,000 cc at 8℃ and the 40,000 cc at 20℃. Off-flavor after storage at 1℃ were lower at the 10,000 cc and 20,000 cc film, and the 40,000 cc and 20,000 cc film each had the lowest result of 8℃ and 20℃. Firmness showed the highest result at the 40,000 cc film for all three temperatures. The soluble solids of pear was not significantly different among all OTR film treatments and temperatures except for the perforated film treatment. As a results, the conclusion was the suitable type of OTR film was 10,000 cc, at 1℃, 20,000 cc at 8℃, and 40,000 cc at 20℃ for MA storage in ``Niitaka`` pear.
