개화 후 71일 만에 수확된 청매실을 20, 30, 40 두께의 LDPE 필름 포장재에 각각 넣고 상온() 및 저온( 와 1)에 저장하면서 저장 중 일정 시간 간격으로 pH, 산도, 가용성고형분과 클로로필의 함량, 경도, 색상 등의 변화를 측정하여 포장하지 않은 채 저장한 시료에 대한 변화와 비교하였다. 포장재에 넣고 저장한 시료는 포장재의 두께에 관계없이 무포장구에 비해 외관적으로 변화가 훨씬 적음을 확인하였고, 화학적 성질 변화를 억제하는데
Effect of the thickness of low density polyethylene(LDPE) Film as packaging material on changes in physicochemical characteristics of mature-green mume (Prunus mume Sieb. et Zucc) fruits during storage at different temperatures(0, 10 and 25) were investigated. Fruit samples stored in pouches with 30㎛ thickness of LDPE film maintained well not only external qualities such as Shape and firmness, but also internal chemical properties such as pH, acidity, the content of soluble solid and chlorophyll, and color, comparing with samples stored without packaging material or in other pouches with different film thickness(20 and 40㎛). From the results, it was found that the maintenance of quality of mature-green mume fruits during storage at 0, 10 and 25 closely related to the changes in respiratory conditions for fruits affected by the film thickness of the packaging material.
