摘　　要：以壳聚糖、海藻酸钠为成膜基质,甘油为增塑剂,罗伦隐球酵母为拮抗菌,研制一种生物活性膜。通过单因素试验和正交试验得到基础膜的最优配比为壳聚糖2.0%、甘油1.0%、海藻酸钠0.8%;添加拮抗菌所得的生物活性膜具有良好的性能,可作为新型食品防腐保鲜材料,具有广阔的应用前景。A bioactive membrane was developed using chitosan and sodium alginate as the film-forming substrates,glycerol as the plasticizer,and Cryptococcus Laurentii as the antagonist bacteria.Through single factor test and orthogonal test,the optimal ratio of the base membrane was 2.0%chitosan,1.0%glycerol and 0.8%sodium alginate.The bioactive film obtained by adding antagonistic bacteria has good performance and can be used as a new food preservative and fresh-keeping agent,and it has broad application prospect.
