姜黄素是从姜黄根（Curcuma longa L.）中提取的酚类化合物。研究了姜黄素提取物对壳聚糖薄膜性能的影响。测量的薄膜特性包括机械性能、视觉方面、颜色参数、透光性、含水量、水溶性、水蒸气渗透性、红外光谱和抗氧化活性。结果表明，在壳聚糖基薄膜中加入姜黄素可以提高薄膜的黄度和防光性。红外光谱分析表明，提取液中的酚类化合物与壳聚糖相互作用，可能改善了膜的力学性能，降低了膜的含水量、水溶性和透气性。膜的抗氧化活性随着姜黄素提取物浓度的增加而增强。本研究表明将姜黄素提取物掺入壳聚糖薄膜作为活性包装的潜在益处。
Curcumin is a phenolic compound derived from turmeric roots (Curcuma longa L.). This research studied the effects of curcumin extract on the properties of chitosan films. The film characteristics measured included mechanical properties, visual aspects, color parameters, light transmission, moisture content, water solubility, water vapor permeability, infrared spectroscopy, and antioxidant activity. The results suggest that adding curcumin to chitosan-based films increases yellowness and light barriers. Infrared spectroscopy analysis showed interactions between the phenolic compounds of the extract and the chitosan, which may have improved the mechanical properties and reduced the moisture content, water solubility, and water vapor permeability of the films. The antioxidant activity of the films increased with increasing concentrations of the curcumin extract. This study shows the potential benefits of incorporating curcumin extract into chitosan films used as active packaging.
