不同贮存条件对原料乳质量的影响

Effect of different storage situations on raw milk

研究了原料乳质量和贮存温度及贮存时间之间的关系。通过菌落总数的检测和酸度的测定,探讨了不同贮存温度随时间对原料乳中菌落总数和酸度的影响,旨在为优质原料乳的贮运提供参考。结果表明,在4℃贮存条件下,原料乳存放36 h,对质量没有较大的影响;在原料乳温度达到10～15℃的时候,存放时间不宜超过12 h。

The relationship between the quality of raw milk and the storage temperature and time was studied.By testing the colony form unit（CFU）and measuring the acidity of the samples,we discussed how the storage temperature and time affect the quality of raw milk,aiming to provide reference to the storage and transportation of the high-quality raw milk.The results showed that the raw milk can be stored for 36 hours at 4℃,while the raw milk can be stored for less than 12 hours at 10～15℃.
