Abstract

This study was carried out in order to develop an economical and convenient way to improve storability of sweet persimmon 'Fuyu'. Natural porous materials (bamboo active carbon, chaff charcoal, and Ge-lite) pouching bags were enveloped in the conventional LDPE (low density polyethylene) package during room temperature and low temperature storage. The changes of soluble solids content, flesh firmness, flavor, decay, and softening of sweet persimmon were investigated in the 1- or 2-week intervals. The LDPE packaging with bamboo active carbon treatment was confirmed to maintain longer storability and higher quality than the LDPE packaging only. This method is expected to be applied to both of conventional and organic farming as an economical and convenient way to improve storability on long term storage and during distribution.

단감을 재배하는 농가에서 저장성을 향상 시킬 수 있는 값싸고 쉬운 방법을 개발하기 위해 본 연구를 수행했다. 농가 관행 LDPE 포장재 내에 동봉할 수 있는 천연소재(대나무활성숯, 왕겨숯, 겔라이트)를 선발하여 상온과 저온환경에서 가용성 고형물 함량, 경도, 식미, 부패도, 연화도의 변화를 1주일 또는 2주일 간격으로 조사하였다. 대나무활성숯을 동봉한 LDPE 포장 방법이 단순 LDPE 포장 방법 보다 저장성 및 품질을 을 좋게 유지하였다. 대나무활성숯을 동봉한 LDPE 포장 방법은 관행 농법 농가와 유기 농법 농가 모두에서 장기 저장 시 그리고 유통 중 온도변화 시 저장성을 향상 시킬수 있는 값싸고, 손쉬운 방법으로 활용할 수 있을 것으로 판단된다.
