1、现代食品科技ModernFoodScienceandTechnology2016,Vol.32,No.4气调运输包装方式对荔枝保鲜品质的影响吕恩利,陆华忠,杨松夏,赵俊宏,田庆立(华南农业大学工程学院,南方农业机械与装备关键技术教育部重点实验室,广东广州510642)摘要:为掌握气调保鲜运输中不同包装方式对荔枝保鲜品质的影响,以“淮枝”荔枝为试验材料,采用气调保鲜运输试验平台模拟保鲜运输试验,研究了气调运输中密封包装、无包装、孔袋包装等包装方式荔枝保鲜品质的变化。研究表明:整体而言,3种包装方式的保鲜效果由好到差依次为孔袋包装、密封包装、无包装;相对于无包装方式,密封包装
2、方式和孔袋包装方式均可以明显地抑制荔枝质量损失率的下降和褐变指数的上升,运输至35d时质量损失率均为3%以内;孔袋包装可以更好的抑制荔枝褐变和维持荔枝较高的好果率水平,运输至第7d时仍可维持90%以上的好果率;在抑制质量损失率下降、抑制可溶性固形物和可滴定酸物质的分解方面,密封包装方式和孔袋包装方式无明显差异,而密封包装在运输7d后可引起可滴定酸含量的上升。该研究为提高荔枝气调保鲜运输保鲜效果提供参考。关键字:气调;包装;荔枝;保鲜品质文章篇号:1673-9078(2016)4-156-160DOI:10.13982/j.mfst.1673-9078.2016.4.025
