不同脂肪含量驴乳产能营养素能量组成分析

分析不同脂肪含量驴乳产能营养素占总能量的比例及其营养价值。结果表明,平均脂肪含量0.89%~1.24%的驴乳,脂肪、蛋白质、碳水化合物(乳糖)产能占总能量的比例分别为20.25%~25.41%、12.99%~18.24%、57.46%~65.03%,符合中国营养学会推荐的我国成年人膳食中各种产能营养素能量比例的要求;脂肪含量较高的驴乳,总能量、人体必需脂肪酸和脂溶性维生素含量较高,各种产能营养素占总能量的比例更适合人体代谢和健康需要,具有较高的营养价值。

Analysis on Energy Composition of Energy-yielding Nutrients in Donkey Milk with Different Fat Contents

The study analyzes the ratio of energy-yielding nutrients to the total energy in donkey milk with different fat contents.The result shows the ratio of the energy from fat,protein,carbohydrate(lactose)to total energy in donkey milk with an average fat content of 0.89%to 1.24%are 20.25%~25.41%,12.99%~18.24%,57.46%~65.03%respectively,which meets Chinese adult's energy-yielding nutrient percentage requirement recommended by Chinese Nutrition Society.Donkey milk with the fat content of 0.89%to 1.24%has relatively high nutritional value.
