花青素和皮克林乳液改善胶原膜性能的研究
Research on the improvement of collagen film properties by anthocyanin and Pickering emulsion
摘要
Abstract
To improve the functional activity of collagen films and expand their applications in the field of active and intelligent packaging.The antibacterial/antioxidant agent(cinnamon essential oil-based Pickering emulsion)and three pH-sensitizing anthocyanins from different plant sources(black wolfberryextract,BWE;black riceextract,BRE;bilberry extract,BE)were incorporated into collagen film matrix to prepare multi-functional collagen films(COL-BWE,COL-BRE,and COL-BE).The pH-responsiveness,antimicrobial activity,antioxidant activity,thermal stability,light barrier properties,and microstructure of the films were characterized.The results showed that the addition of Pickering emulsion and anthocyanins improved the functional activities of collagen film.Compared with collagen film,the pH-responsiveness of the multi-functional films varied from insensitive to showing pH-responsive color change,the bacteriostatic activity increased from 0%to 94.74%,and the antioxidant activity increased from 6.39%to 92.51%.The films alsodemonstrated enhancedthermal stability(from 66.60℃to 72.20℃)and light-blocking properties.The degree of enhancement was dependent on the anthocyanin plant source,with BE being the most compatible with the collagen/Pickering emulsion film matrix.The COL-BE films demonstrated the most significant performance enhancement(COL-BE＞COL-BRE＞COL-BWE).The study providesa reference for the development and utilization of collagen-based active and intelligent packaging films.关键词
