鲜切苹果自发气调包装研究

Research on Modified Atmosphere Package of Fresh-cut Apples

以低密度聚乙烯、高密度聚乙烯、聚丙烯膜为包装材料,研究其对鲜切苹果的保鲜效果。结果表明:3种保鲜膜包装均能不同程度地抑制鲜切苹果呼吸强度,推迟呼吸高峰期到来,减少营养物质消耗,0.04mmLDPE保鲜膜较适合于鲜切苹果的自发气调包装。

The effect of Modified Atmosphere Package materials such as,low density polyethylene,high density polyethylene and polypropylene were studied for the preservation of fresh-cut apples.The results showed that respiration intensity of fresh-cut apples packing by three films was inhibited to some extent and the appearance of respiration peak was postponed, nutritional lose was lessened simultaneity. 0.04mmLDPE film was more suitable lot spontaneous modified atmosphere packaging of fresh-cut apples.
