CA 저장 사과로 제조한 신선절단 사과의 비타민 C 강화와 품질유지기간을 연장하기 위한 방법을 개발하기 위한 일환으로 신선절단 사과를 10% L-ascorbic acid 용액에 침지처리하고 0.03 mm LDPE, 0.04 mm PP 및 0.08 mm Nylon/PE(질소치환) 필름으로 포장하여 1에서 저장하면서 포장내 기체농도와 품질변화를 조사하였다. 저장 중 포장내 산소는 Nylon/PE 포장구에서 가장 낮게 l~3%로 유지되었고 다음으로 P
To develop and extend the shelf-life of vitamin C enriched fresh-cut apples using CA stored Fuji apples, dipping in 10% L-ascorbic acid and packaging with 0.03 mm LDPE, 0.04 mm PP and 0.08 mm Nylon/PE film(Ndisplacement) were carried out. The changes of gas concentrations in the packaging and quality attributes of fresh-cut apples were examined during storage at 10. The concentrations of Owas maintained lower in Nylon/PE film than the other film, the level of Owas in the range of 1∼3%. The increase of CH concentrations in Nylon/PE film bag was more suppressed than the others. The vitamin C content of fresh-cut apples was enriched by dipping in L-ascorbic acid solution up to 241 mg100 g-1 f.w., and the loss or that content was retarded differently by the package conditions of lower Olevel during storage. Browning in fresh-cut apples was shown after 6 days of storage in LDPE and PP film. but it was not shown by 14 days of storage in Nylon/PE film. Spoilage and off odor in fresh-cut apples were not detected up to 14 days of storage in Nylon/PE film. The results indicated that the vitamin C enriched fresh-cut apples can be processed from the long-term CA stored apples, and maintaining high quality of the products ill be possible in cases of the application of sealing packaging after Oremoval with film having low Opermeability.
