Temperature and Quality Changes of Pasteurized Milk during Refrigerated Distribution

抄録

To investigate temperature and quality changes of pasteurized milk during refrigerated distribution, parameters of distribution temperature and time were obtained by means of measuring the distribution vehicles. Then the total number of bacteria colony, acidity and protein content of pasteurized milk were investigated in the conditions of 8C and 10C with the control group of 2C. The results showed that the temperature of at the doorway and in the center of carriage would be lower than that of innermost, as well as quality change would have been speeded up after 12 hourshours distribution.
