抗菌肽及其在食物储藏与保鲜中的应用

Antimicrobial Peptides and Their Applications in Food Storage and Preservation

摘要:

抗菌肽是抵抗外源病原微生物的天然免疫小分子多肽，存在于多种生物体内，具有广谱抗菌、可抑制多重耐药菌的繁殖、活性稳定、免疫原性低、绿色无公害等优点，在食物储藏与保鲜中显示了巨大的应用潜力。对抗菌肽的功能、制备方法、抗菌机制及其在食品储藏和保鲜中的应用进行了总结分析，以期为发展有针对性的新型食物保鲜剂提供思路。

Abstract:

Antimicrobial peptides(AMPs) are small molecules of natural innate immune system against the exogenous pathogenic microorganisms. AMPs are found in a variety of organisms and possess broad-spectrum activity, capacity of inhibiting the proliferation of multidrug-resistant bacteria, stable activity, low immunogenicity, green pollution-free characteristics and so on. AMPs show great potential in food storage and preservation. The functions, preparation, antibacterial mechanism and application of AMPs in food storage and preservation were summarized and analyzed in order to provide ideas for the development of targeted new food preservatives.
