Abstract: The characteristics of roof-packed yogurt with different packaging materials such as Lactobacillus number,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 blue roof-packaging was the most stable of the four samples,followed by the yellow roof-packaging.Considering the protection of vitamin C and proliferation of Lactobacillus,the red roof-packaging is worse than blue and yellow ones,and the white roof-packaging is the worst for yogurt content protection.
