A new composite film was developed by combining Gelidium corneum (GC) with chitosan to enhance the physicochemical characteristics of GC film. In addition, to confer new functional property on the GC-chitosan composite film, various amounts (0.5%, 1.0%, and 1.5%) of java citronella essential oil (JCEO) were incorporated into the film. As the concentration of JCEO increased, the extensibility of the GC-chitosan film improved. In addition, the film became more opaque due to decreased light transmission. Especially, ultraviolet light was completely blocked in the composite films containing JCEO. Radical scavenging activities of the films also increased with increasing JCEO content, indicating that the films have antioxidant activity. Therefore, GC-chitosan composite film containing JCEO is applicable in food packaging to preserve food quality by retarding lipid oxidation.

通过结合角质层胶开发了一种新的复合膜（GC）与壳聚糖一起增强了GC膜的理化特性。另外，为了赋予GC-壳聚糖复合膜新的功能特性，将各种量（0.5％，1.0％和1.5％）的香茅精油（JCEO）掺入该膜中。随着JCEO浓度的增加，GC-壳聚糖膜的延展性提高。另外，由于透光率降低，膜变得更不透明。特别是，在含有JCEO的复合膜中紫外线被完全阻挡。膜的自由基清除活性也随着JCEO含量的增加而增加，表明膜具有抗氧化活性。因此，含有JCEO的GC-壳聚糖复合膜可用于食品包装中，通过阻止脂质氧化来保持食品质量。
