Determination of Freezing Point of Raw Donkey Milk

Objective This paper of Kashi two households donkey milk farmers fresh donkey milk freezing point of detection and watered test,aims to analyze the donkey milk freezing point is able to become the main basis of donkey milk watered.Method UL80BC type milk analyzer was used to determine the freezing point of 50 raw donkey milk samples from the two Xinjiang Yuepuhu County dairy farmers.Result Freezing point average of donkey milk was-0.563℃,ranging in-0.671--0.530℃.A household eaw donkey milk added with 1; had no significant difference (P ＞ 0.05),and water and 2; had significant difference (P ＜ 0.05),B households fresh donkey milk added with 1; had significant difference (P ＜ 0.05),and 2; of water have significant difference (P ＜ 0.01),the A and B family added with 4;,adding 6; had significant difference (P ＜ 0.01).Conclusion Adding water in the fresh donkey milk,the freezing point rises up,and more water added,the higher it will be.But,the milk with 1; of water,the freezing point decreases with the increase of water content.
