摘　　要：按GB4789．18-2010《乳与乳制品检验》标准对云南省主要奶水牛养殖小区、合作社同一季节26户养殖户的228个水牛生乳及相同来源不同月份的655个水牛生乳的酸度进行滴定，同时进行酒精检测和掺碱试验，并对日粮组成、饲喂模式及胎次和泌乳天数进行普查。同一季节不同来源的228个水牛生乳滴定酸度在10-13°T的占83．8％；相同来源不同月份的655个水牛生乳样品的滴定酸度在10-13°T的占86．4％；总的883个生鲜水牛乳滴定酸度为10-13°T的占85．7％，大于14°T占10．6％，小于10°T仅占3．6％。Titration acidity of different buffalo raw milk samples were investigated in both in the same and different season according to GB 4789.18--2010 of ＂milk and dairy products inspection＂. Among the samples, 228 of them were from major buffalo farming community in Yunnan Province, and 655 were from 26 farmers. The alcohol and al- kali-doped were test, and the composition of the diet, feeding patterns and parity and lactation days of buffalo were also surveyed.The results showed that the titratable acidity of milk buffers with milk titers ranging from 10 to 13 °T was accounted for 85.7%, and 10.6% of the titratable acidity was more than 14 °T. Only 3.6% in 883 samples was found their acidities were less than 10 ° T. Moreover, 83.8% in 228 samples of different origins at the same sea- son were found with the titratable acidity ranging from 10 to 13 °T, and the titratable acidity of 86.4% in 655 samples from same origins at the different season ranged from 10 to 13 °T.
