摘要
以津春2号黄瓜为试材,采用厚度均为0.03 mm的微孔保鲜膜与常规低密度聚乙烯(LDPE)膜分别包装,贮藏于(12±1)℃、相对湿度85%的条件下,研究贮藏期内黄瓜失重率、硬度、可滴定酸、叶绿素和Vc含量的变化。实验结果表明:与对照LDPE膜相比,微孔保鲜膜贮藏有利于保持津春2号黄瓜的水分和硬度,有利于减缓叶绿素的降解,对可滴定酸和Vc的作用不明显。
The cucumber of "Jinchun 2"was packed with the 0.03 mm microporous film and 0.03 mm low density polyethylene (LDPE) film respectively,and was stored under the condition of (12 ±1) de-gree of temperature ,and relative humidity of 85% as the test material .The changes in content of weight loss rate,firmness,titrable acid,chlorophyll,vitamin C were studied during the storage time .The experi-mental results indicated that:the water and firmness of the cucumber packed by microporous film could be effectively maintain ,the degradation of chlorophyll could be slowed down ,the titrable acid and vitamin C were not influenced clearly .
