In order to obtain an eco-friendly and multifunctional preservative film, dehydroabietic acid (DHA) modified chitosan (CS) containing wintergreen essential oil (CSDA-WEO) film was developed. CS grafted by DHA was able to increase the deformation capacity of CS film (MCS) by about 12.5 %, and the film made by CSDA containing WEO increased the tensile deformation capacity to 32 %. CSDA-WEO film (MCSDA-WEO) can improve the transmittance and UV blocking, and MCSDA-WEO can be completely degraded within 35 days. In the Film-2 approach, PE film (MPE), CSDA film (MCSDA) and MCSDA-WEO again improve the preservative performance based on the original 1 approach and have good freshness preservation. MCSDA and MCSDA-WEO were able to delay the loss of antioxidant activity, improve the antifungal property and prolong the shelf life of mandarins up to 18 days. MCSDA and MCSDA-WEO have good performance, are green and healthy, and have a wide perspective for food preservation.
为了获得一种环保且多功能的保鲜薄膜，开发了一种含有冬青油的脱氢枞酸（DHA）改性壳聚糖（CS）（CSDA-WEO）薄膜。用 DHA 接枝的 CS 能够将 CS 薄膜（MCS）的变形能力提高约 12.5%，而含有 WEO 的 CSDA 制成的薄膜则将拉伸变形能力提高到 32%。CSDA-WEO 薄膜（MCSDA-WEO）可以提高透光率和紫外线阻隔率，并且 MCSDA-WEO 在 35 天内可以完全降解。在薄膜 2 方法中，PE 薄膜（MPE）、CSDA 薄膜（MCSDA）和 MCSDA-WEO 再次基于原始 1 方法提高了保鲜性能，并具有良好的保鲜效果。MCSDA 和 MCSDA-WEO 能够延缓抗氧化活性的损失，提高抗真菌性能，将蜜桔的保质期延长至 18 天。MCSDA 和 MCSDA-WEO 具有良好的性能，绿色健康，在食品保鲜方面具有广阔的前景。
