目的 综述以海藻酸钠为主要基材制备抗菌包装材料的研究进展。方法 通过对国内外研究成果与研究现状的分析与总结， 探讨海藻酸钠在缓控释抗菌包装材料的研究前景。结果 分析表明以物理方法直接载抗菌活性物质的海藻酸钠基包装材料， 在短时间内其抑菌效果明显， 随着时间的增加，抗菌活性物质释放量减少， 抑菌效果下降。利用化学改性海藻酸钠载入抗菌活性物质， 在一定程度上能够提升抗菌物质的包埋率， 增加抑菌作用时间。结论 基于海藻酸钠的缓控释抗菌包装材料研究尚处在起步阶段， 对海藻酸纳及其衍生物进行进一步改性后， 使其成为良好缓控释抗菌包装载体材料的潜力非常巨大。

This paper reviewed the research progress in antimicrobial packaging materials prepared using alginate as the major base material. This paper discussed the prospects of sodium alginate-based materials applied to antimicrobial packaging through analysis and summarization of the research results and the current research status all over the world. The analysis showed that sodium alginate-based packaging materials directly carrying active antimicrobial substances prepared using physical methods showed obvious antibacterial effect in a short time, and the released amount of antimicrobial substance reduced obviously and the antibacterial effect decreased with the prolonged time. On the other hand, chemically modified sodium alginate-based packaging materials carrying active antimicrobial substances showed increased embedding rate of the antimicrobial substance as well as prolonged effective antibacterial time. In conclusion, the research on controlled and sustained-release antimicrobial packaging materials based on sodium alginate has just started. Through further modification of the properties of sodium alginate and its derivatives, there would be a great application prospect in the respect of controlled and sustained-release antimicrobial packaging materials.
