摘要
研究了塑料桶、屋顶盒、袋装这三种包装的纯鲜牛乳在4℃冷藏光照、4℃冷藏避光两个贮藏条件下,滴定酸度、粗蛋白含量、细菌总数以及维生素C含量在贮藏期内的变化。结果表明,屋顶盒包装为三种包装中稳定性最好,袋装包装在光照条件下对内容物的保护作用最差,桶装包装各方面性能居中。
The quality changes characteristics of milk such as of milk with different package materials during storage were studie＆ The microbial, titration acidy, content of total protein and content of ascorbic acid at different temperatures in two illumination situations were analyzed continuously. The results showed that the roof-packed was the most stable of the three samples. At the same time, bag for packaging was the worst as milk content protection and the performance of the bottled packaging was general.
