果蔬保鲜膜的研究进展

Review of Preservative Film for Fruits and Vegetables

果蔬保鲜应控制包装储存环境中O_2和CO_2的体积比,控制储存环境的相对湿度,及时排除果蔬在包装存储中释放的乙烯、乙醇等气体。果蔬保鲜膜主要有普通保鲜膜、微孔保鲜膜、防雾功能保鲜膜、可食性保鲜膜、硅窗调气保鲜膜和抗菌保鲜膜等。在果蔬保鲜的实际应用中,一般采用复合式保鲜法。多功能保鲜膜及可降解的无公害保鲜膜将是今后果蔬保鲜膜的发展趋势。

The volume ratio of 02 and CO2 and the relative humidity in the storage environment for fruit and vegetable packaging should be controlled in fruit and vegetable preservation process. Gases released in vegetable packaging storing such as ethylene, ethanol should be removed in time. The main types for preservation films for fruits and vegetables include ordinary plastic film, micro porous plastic film, anti-fog function plastic film, edible plastic film, silicon window plastic film, transfer gas and antibacterial film. In the practical application for fresh fruits and vegetables, composite preservation method is commonly used. Multifunction plastic film and biodegradable pollution-free plastic film will be the future trend in the development of the fruit and vegetable plastic film.
