准噶尔双峰驼驼乳营养与功能成分与荷斯坦牛乳的差异比较分析

【目的】分析比较准噶尔双峰驼乳和荷斯坦牛乳的差异，为研究驼乳的营养价值和生物学功能提供科学基础。【方法】使用乳成分分析仪、电感耦合等离子体光度发射光谱法、气相色谱和ELISA检测乳的主要营养成分、理化特性、脂肪酸和主要生物活性物质含量。【结果】准噶尔双峰驼乳中乳蛋白、乳糖、钙、灰分、干物质显著高于荷斯坦牛乳(P<0.05)。乳密度也显著高于荷斯坦牛乳(P<0.05)。乳脂中花生酸、二十一碳酸、棕榈油酸和α-亚麻酸显著高于荷斯坦牛乳(P<0.05)。而准噶尔双峰驼乳的电导率、酸碱度、水分显著低于荷斯坦牛乳(P<0.05)。顺-8,11,14-二十碳三烯酸、己酸、辛酸、癸酸和月桂酸显著低于荷斯坦牛乳(P<0.05)。但两乳中所检测的生物活性成分含量无显著差异(P> 0.05)。【结论】准噶尔双峰驼乳相较于荷斯坦牛乳存在诸多显著性差异。

A Comparative Analysis of Milk Nutritional and Functional Components between Junggar Bactrian Camel and Holstein Cow

【Objective】 To compare the milk differences between Junggar Bactrian camel and Holstein dairy cow, and to provide a scientific basis for comprehensive understanding of the nutritional value and biological function of camel milk. 【Methods】 Milk composition analyzer, inductively coupled plasma-optical emission spectrometry, gas chromatography, and ELISA were used to detect the main nutrients, physicochemical characteristics, fatty acids and main bioactive substances content of milk. 【Results】 The contents of milk protein, lactose, calcium, ash, dry matter, density, eicosanoic acid, heneicosylic acid, palmitoleic acid and ALA content in the Junggar Bactrian Camel milk were significantly higher than those in the Holstein dairy cow(P < 0.05).However, conductivity, pH value, water, cis-8, 11, 14-eicosatrienoic acid, caproic acid, caprylic acid, capric acid, lauric acid content in the Junggar Bactrian Camel were significantly lower than those in the Holstein dairy cow (P < 0.05).There was no significant difference in bioactive substances detected(P > 0.05). 【Conclusion】 There were many significant differences between Junggar Bactrian camel milk and Holstein dairy cow milk.
