静电纺丝技术包埋抗菌物质研究进展

近年来,人们已成功地开发出多种不同来源的天然抗菌物质。由于食品加工和储存条件对其抗菌效果产生很大的影响,极大地限制了其在食品工业中的应用。目前常用的包埋技术在包埋抗菌物质时仍存在许多不足之处。因此,开发出高效包埋天然抗菌物质的包埋技术成为研究的热点问题。静电纺丝技术是一种新颖的、简单的生物活性物质包埋技术,能够显著提高生物活性物质的包埋效率、稳定性和利用度,在一定程度上克服了传统包埋技术在包埋生物活性物质时的弊端。本文主要综述了静电纺丝技术的原理,纺丝参数对静电纺丝纳米纤维的影响以及以多糖和蛋白质为基质利用静电纺丝技术包埋抗菌物质及其应用的研究进展,为其在食品工业中的良好应用奠定基础。

Research Progress of the Encapsulation of Antimicrobial Substances by Electrospinning Technique

Recently,many natural antimicrobial substances from different sources have been successfully developed. The environments of regular food processing and storage significantly impact their antibacterial effect,which prevent their application in food industry. The commonly encapsulation techniques still have many shortcomings with encapsulate antimicrobial substances. Thus,developing a new strategy to effectively encapsulate antimicrobial substances has become a hot scientific research. Electrospinning technology is a novel and simple technique to encapsulate bioactive compounds. It could obviously enhance the encapsulation efficiency,stability,and bioavailability of bioactive compounds,as well as overcome barrier performance compared to conventional capsulation techniques. This paper mainly summarized the principle of electrospinning technology and the influence of spinning parameters on electrospinning nanofiber. And the encapsulation and application of antimicrobial substances with polysaccharides and proteins as the substrates via electrospinning technique was also reviewed,which provided a foundation for its good application in food industry.
