可食性绿色包装膜的研究进展

目的 探索“智慧课堂”教学模式对高校专业课程教学改革与人才培养的影响。方法 以《食品添加剂》课程教学为例，分析了传统课程教学的现状与存在问题，探讨了将智慧树运营服务平台应用于课程教学的方法，提出“智慧课堂”教学的优势所在和总体思路，并对其解决方法予以阐述，还通过调查问卷对教学改革结果予以反馈。结果 61.9%的调查对象认为通过“智慧课堂”教学方式能获得问题分析能力的提升;58.73%的调查对象认为能获得总结凝练与自主学习能力的提升;52.38%的调查对象更乐意采用线上线下混合式教学;57.14%的调查对象觉得《食品添加剂》课程分值分配比例很合理，并有61.9%受访者表示非常乐意接受该教学模式。结论 实践证明，“智慧课堂”教学模式能提高学生对课程学习的兴趣和主动性，达到理论学习与人才培养的双重目标，值得应用推广。

Research Progress on Edible Green Packaging Film

The work aims to discuss the category, technology and research progress of different edible packaging films and provide technical support and scientific basis for development and application of this material. With edible film as a research subject, the kinds, properties, preparation methods and application status of different edible food such as edible polysaccharide membrane, edible protein membrane, edible lipid membrane and edible composite film were analyzed. The research on the development and performance of edible packaging film has been more and more in-depth and has made some achievements, but there are still many kinds of performance defects that limit its wide application. The research and application of edible packaging film is an important direction of food science and technology development in the world. At present, a lot of experiments and analysis are required from the research and development of materials to practical application in packaging. The development of edible film materials which has excellent performance with environmental friendliness and biosafety not only accords with the main research trend of packaging materials, but also has broad application prospect and market value.
