Composition, nutritional value and sensory characteristics of donkey milk of Indian small grey breed was analysed using AOAC and other standard methods. Fresh donkey milk had 90.63% (w.b.) moisture content, 0.76% fat, 1.96% protein, 6.30% lactose, 0.40% ash. Particle size of donkey milk was 355.00 d.nm. The UHPLC analysis ascertained that lysozyme content was more in donkey milk sample. The ICPMS confirmed that Ca, K, Mg, Na, vitamin C and E, glutamic acid, leucine, proline were the most abundant in donkey milk, but Fe, Zn, Vitamin A and B1, methionine shown lower amount. The GC analysis determined that butyric acid, lauric acid was more and lower amount of unsaturated fatty acids were observed in donkey milk sample. Finally, the TPC, yeast and mould count were acceptable and confirmed that donkey milk is microbiologically safe and sensory evaluation studies of donkey milk confirmed that the desired sensory attributes.
采用美国官方分析化学师协会（AOAC）及其他标准方法，对印度小灰驴品种的驴奶成分、营养价值和感官特性进行了分析。新鲜驴奶的水分含量为90.63%（湿基），脂肪含量为0.76%，蛋白质含量为1.96%，乳糖含量为6.30%，灰分含量为0.40%。驴奶的粒径为355.00 d.nm。超高效液相色谱（UHPLC）分析确定驴奶样品中的溶菌酶含量更高。电感耦合等离子体质谱（ICPMS）证实，钙、钾、镁、钠、维生素C和E、谷氨酸、亮氨酸、脯氨酸在驴奶中含量最为丰富，但铁、锌、维生素A和B1、蛋氨酸含量较低。气相色谱（GC）分析确定，驴奶样品中丁酸、月桂酸含量较高，不饱和脂肪酸含量较低。最后，总酚含量、酵母和霉菌计数均在可接受范围内，证实驴奶在微生物学上是安全的，驴奶的感官评价研究也证实了其具有理想的感官特性。
