Abstract

For the development of kiwifruit storage method applicable to farm level, several quality indicator of kiwifruit(Actinidia chinensis Planch.) were measured during storage at modified atmosphere(MA) conditions(0.04, 0.06, 0.08 and 0.10 mm PE Film). The results obtained from the experiment were as follows. The highest firmness was marked by the kiwifruit kept in 0.06 mm thick film bag and the lowest weight loss was shown in 0.10 mm thick film bag. The largest production of respiratory rate was occured after storage for 30 days. The concentration of $O_2\;and\;CO_2$ in 0.06 mm thick film bag was 2.6% and 3.2% after storage for 60 days, respectively. It could be concluded that the optimum PE film thickness for MA storage of kiwifruit was 0.06 mm.

농가규모에서 실용적인 양다래의 저장방법을 개발하기 위하여 PE 필름을 두께별(0.04 mm, 0.06mm, 0.08mm 그리고 0.10mm)로 일정량씩 양다래를 넣고 저장하였던 결과를 요약하면 다음과 같다. 가장 우수한 과실의 경도값을 보인 구는 0.06mm 밀봉구로 나타났으며 0.10mm 밀봉구의 경우 중량감소율이 가장 적었다. 또한 저장 30일 경과후에 양다래 과실의 호흡율이 최고값을 나타내었다. 0.06mm 밀봉구의 저장 60일 경과후 산소 및 탄산가스의 농도는 2.6%와 3.2%의 값을 보였다. 이러한 결과로써 양다래의 적합한 MA 저장 조건은 0.06 mm PE 밀봉구로 판단되어졌다.
