中文摘要:

      目的 介绍茶多酚良好的抗氧化性、抑菌性，综述国内外将茶多酚与可降解成膜基材复合后应用于食品保鲜的研究进展，为后续研究提供基础。方法 通过对国内外研究现状和研究成果的综述，介绍茶多酚的保鲜机理及与可降解成膜基质复合后在食品保鲜（肉类、蔬菜类、水果类等）方面的具体应用，并分析茶多酚的加入对复合膜保鲜效果的影响。结论 从发展趋势来看，可降解食品保鲜材料必将拥有广阔的发展前景。茶多酚的添加虽使得可降解复合膜的保鲜效果大大增加，但国内外在茶多酚复合保鲜材料方面的研究形式相对较单一，多以复合膜或者膜液形式进行保鲜。利用微胶囊技术与茶多酚复合保鲜材料相结合制备保鲜剂，既能够更好地控制保鲜剂的使用量，又能避免直接与食品过多接触，是一个值得尝试的新思路。

英文摘要:

      The work aims to introduce the good antioxidant and bacteriostatic properties of tea polyphenols, and to summarize the research progress of the application of tea polyphenols and degradable film-forming substrates at home and abroad in food preservation, so as to provide a basis for further research. Through the summary of research status and research results at home and abroad, the preservation mechanism of tea polyphenol and specific application of its recombination with degradable film-forming substrate in food preservation (meat, vegetables, fruits, etc.) were introduced. The effect of the addition of tea polyphenols on the preservation effect of the composite film was analyzed. Biodegradable food preservation materials will have broad development prospects from the perspective of development trend. The addition of tea polyphenols will greatly increase the preservation effect of degradable composite films, but the research forms of tea polyphenol composite preservation materials at home and abroad are relatively simple, mostly in the form of composite film or film liquid preservation. The use of microcapsule technology combined with tea polyphenol composite preservation materials to prepare preservatives can not only control the amount of preservatives better, but also avoid direct contact with food too much, which is also a new idea worth trying.
