플라스틱 필름포장 내 에틸렌제거가 사과 '쓰가루' 과실의 저장 품질에 미치는 영향 = Effect of Ethylene Scrubber in Polyethyene Film Wrap on the Storage of 'Tsugaru' Apples

다국어 초록 (Multilingual Abstract)

This study was conducted to develop an appropriate postharvest technique to extend the shelf-life of an early cultivar, 'Tsugaru' apples.
The general quality of stored fruti was more affected by maturity at harvest than postharvest treatments. When firmness and internal quality were considered, fruits harvested at the medium stage of color development showed better results. Between postharvest treatments examined in this study, a simple polyethylene film(PE) wrapping (30um) was excellent on inhibition of weight loss but this treatment revealed no clear effect on other quality factors including firmness and acidity. Ethylene scrubber(ES) in polyethylene wrapping showed a positive effect on keeping fruit quality in general. Especially acid content was higher in fruit stored with PE + ES, thus, fruit seemed to be better in freshness.
A physiological disorder was observed regardless postharvest treatments. The symptom was associated with incidence of pitting on surface and breakdown of the effected tissue. And much more symptoms were developed near the calyx end. Thus, future studies concerning 'Tsugaru' storage should include an examination of the optimum storage temperature.
