摘　　要：缓释型抗菌包装是具有缓慢释放抗菌成分性能的一种活性包装。利用β-环糊精包埋异硫氰酸烯丙酯制备抗菌复合物,并将复合物与聚乳酸、聚乙二醇共混挤压吹塑制备了抗菌包装膜,研究了抗菌包装材料中异硫氰酸烯丙酯在不同环境条件下的释放规律和对常见食品微生物的抑制作用。结果表明,挥发性抗菌剂经过环糊精包埋,其耐热性得到明显提高,热加工损失率从98.77%降低到75.56%;抗菌包装控制抗菌剂释放的速率随着环境湿度和温度的升高而增大;同时,此抗菌包装对常见食品微生物具有较强的抑制作用,其中对酵母、霉菌的抑制作用强于细菌。The sustained-release antimicrobial packaging is a kind of material that has the special property of releasing active antibacterial component slowly.In this study,antibacterial complex was firstly prepared by forming inculsions between allyl isothiocyanate（AITC）and 13-CD.And then 13-CD-AITC complex,was mixed together with PLA and PEG.These blenders were then extruded and blown for making the antimicrobial packaging.The release of AITC and its antibacterial effect were mainly investigated.The obtained data suggested that, firstly, the heat- resistant ability of volatile antimicrobiais had been improved markedly,as can be seen from the less loss rate of AITC about ？5.56% when processing in extruder, compared with that of 98.7？% before forming inclusions. Secondly,the release rate of AITC increased with the environmental temperature and humidity rising.Thirdly,the prepared antimicrobial packaging showed quite strong inhibitory effect on the main microorganism in food, especially on yeast and mould.
