摘　　要：研究了不同储运条件对UHT(Ultra High Temperature treated)灭菌乳中糠氨酸含量的影响。将UHT灭菌乳分别储存于冷冻条件(-20℃储存6个月)、冷藏条件(4℃储存6个月)、室温条件(25℃储存5个月),模拟夏季高温条件(37℃储存3个月后25℃储存2个月)和模拟高温长途运输条件(65℃储存6 d后25℃或37℃储存5个月),定期检测UHT灭菌乳中糠氨酸含量,探索不同储存条件对UHT灭菌乳中糠氨酸含量的影响。本试验得出,冷冻条件和冷藏条件下,UHT灭菌乳中糠氨酸含量无显著变化(P>0.05);室温条件、模拟夏季高温条件和模拟高温长途运输条件下,UHT灭菌乳中糠氨酸含量均有显著增长(P<0.05)。The effect of different storage and transportation temperature on the content of furosine in UHT milk were studied.To explore the change of furosine content,UHT milk samples were stored at-20,4,25℃(room temperature),37℃(simulated summer high temperature conditions)and 65℃(simulated high temperature long-distance transportation conditions),respectively.The results showed that the content of furosine in UHT milk samples were not changed(P>0.05)when stored at-20℃and 4℃.The content of furosine in UHT milk samples significantly increased(P<0.05)when stored at 25℃,37℃and 65℃.
