The aim of this work was to shed light on the nutritional ingredients and antioxidant activity of donkey milk and powder. It indicated that basic components of donkey milk were closed to human milk, especially lactose. The fat content of donkey milk was lower than that of cow milk and human milk. The essential amino acids, fatty acids and taurine in donkey milk and powder were richer. The whey protein content of donkey milk was 49.08 g/100 g. The ratio of casein to whey protein in donkey milk and powder was 70.3:100. The cholesterol of donkey milk was 8.6 mg/100 g. Therefore, donkey milk and powder are typical low-fat and low-cholesterol foods. The precious values of donkey milk and powder are suitable calcium and phosphorus proportion, and strongly resistant to oxidation. In conclusion, donkey milk and powder are good supplementary of cow milk and powder, would be better for infant dietary.
这项工作的目的是阐明驴奶及驴奶粉的营养成分和抗氧化活性。研究表明，驴奶的基本成分与母乳相近，尤其是乳糖。驴奶的脂肪含量低于牛奶和母乳。驴奶及驴奶粉中的必需氨基酸、脂肪酸和牛磺酸更为丰富。驴奶的乳清蛋白含量为49.08克/100克。驴奶及驴奶粉中酪蛋白与乳清蛋白的比例为70.3:100。驴奶的胆固醇含量为8.6毫克/100克。因此，驴奶及驴奶粉是典型的低脂、低胆固醇食品。驴奶及驴奶粉的可贵之处在于钙磷比例适宜，且抗氧化能力强。总之，驴奶及驴奶粉是牛奶及牛奶粉的良好补充品，更适合婴儿饮食。
