| 中文摘要: |
| 将柠檬草精油与 PVA 复配成涂膜液,涂布于 LDPE 膜上,制备成具有抑菌功能的复合膜并加工成包装袋,研究了高湿度条件下膜内精油挥发情况以及常温下对葡萄的保鲜效果。 结果表明:随着储藏时间的增加,其精油挥发浓度增大;对葡萄保鲜效果最佳的是 3. 5% 浓度柠檬草精油处理的包装袋,能够将葡萄的货架寿命延长至第 8 天,与空白组对照保质期提高了 1 倍左右。 |
| 英文摘要: |
| Compound solution was mixed with lemon grass oil and PVA; LDPE film was coated with compound solution and antimicrobial bag was prepared used the coated LDPE film. The volatilization of essential oil in film under high humidity condition and the fresh-keeping effect of grape stored under room temperature were studied. The results showed that the concentration of volatile oil increases with increasing storage time; the bag of 3. 5% lemon grass oil concentration has the best fresh-keeping effect for grape, and its storage period is extended to eighth day and is double of control group. |
