| 摘要: |
| 主要研究了纤维素膜的降解性能，并通过其透气性、透湿性和保鲜效果三方面的实验来研究纤维素膜在蔬菜保鲜中的应用。结果表明：1）不同微生物对纤维素膜的降解速度有很大差异；2）纤维素保鲜包装膜降解性能好，采用接种青霉的方法，3天后膜达到全部降解；3）纤维素保鲜包装膜的透气性能优于塑料膜，导致保鲜蔬菜时护绿和防褐变效果差；4）纤维素保鲜包装膜的透湿性能较强，对包装的蔬菜保水性较塑料包装膜差。 |

| Abstract: |
| The degradation of cellulose membrane, and the application of cellulose membrane in fresh vegetables are mainly investigated through studying its permeability, moisture permeability, and preservation. The results show that: 1 ) Different microbial has different degradation rate to cellulose membranes; 2 ) Cellulose packaging film’s degradation performance is the best that it can be depredated fully after three days by inoculating Penicillium; 3 ) Cellulose packaging film’s permeability is better than plastic film, resulting in the poor effects of green color and anti- browning when preserving fresh vegetables; 4 ) Cellulose membrane has so strong water vapor permeability that it’s water retention is worse than the plastic packaging film. |
