摘　　要：介绍了基因工程技术在乳品发酵工业中的应用,并对利用基因工程技术改良乳酸菌发酵剂产生双乙酰的能力、蛋白水解能力、胞外多糖的形成、抗杂菌和病原菌污染特性4个方面的进行研究阐述,还将要介绍了基因工程食品可能存在的不安全问题及解决方法。There are the application of genetic engineering on dairy femetation industry. A review is given had on the stategy ,results,conclu- tion,prospects of genetic modifying,which consists of four parts:protelysis,diacetylproduction,exopolysaccharide,bacterin production.Factors ac- counting for the unsafety of genetic foods were introduced,and so did the method to solve the problem.
