摘要
以未包装的香菇为对照,探讨添加不同质量分数(0%和10%)的乙烯—乙烯醇共聚物(EVOH)的聚己二酸—对苯二甲酸丁二酯(PBAT)/EVOH薄膜对香菇保鲜效果的影响。贮藏条件为温度4 ℃,相对湿度90%,贮藏期间测定包装内气体组分和香菇相关理化指标。结果表明,PBAT/10% EVOH薄膜能使包装环境形成低氧高二氧化碳的气体环境,较好地维持香菇感官品质,保持较高的色泽、硬度和V C 含量。贮藏14 d仍保持较高的感官品质和营养品质。
In order to study preservation effects of blend modified atmosphere film to harvested Lentinus edodes ,compared with unpacked ones, discussed the preservation effect of PBAT/ EVOH blend films in which added different mass fractions of EVOH (0%, 10%) to Lentinus edodes . The gas composition of Lentinus edodes ’ in packaging bag and physical indexes were measured, which stored at 4 ℃ and in humidity of 90%. The results demonstrated that PBAT/10% EVOH blend film could make the packaging environment in a low oxygen and high carbon dioxide status, effectively maintain the sensory quality, such as the color, hardness and vitamin C, in storage period. The sensor and nutrient quality of Lentinus edodes were good after 14 d storage.
