摘  要：
采用密闭高压微波消解法联合电感耦合等离子体发射光谱法分别测定了市场占有率较高的猪皮、牛皮、及鱼皮等3种来源的胶原蛋白肽中K,Ca,P及Na元素的质量分数。结果表明:鱼皮来源的胶原蛋白肽中Ca,P及Na平均质量分数分别为14.05,10.10及63.81 mg/kg,高于猪皮及牛皮来源的胶原蛋白肽;牛皮来源的胶原蛋白肽中K元素平均质量分数为18.67 mg/kg,高于猪皮及鱼皮来源胶原蛋白肽;相同来源的胶原蛋白肽中K,Ca,P及Na元素分布跨度均较大。胶原蛋白肽因其来源和制备工艺的不同,其元素组成差异较大,作为原辅料在食品工业中选择应用时,建议进行矿物质质量分数的分析并批检。

摘  要：
The mass concentrations of K, Ca, P and Na in collagen peptides derived from pig skin, cow skin, and fish skin that widely used in food market were measured by a closed high-pressure microwave digestion method combined with inductively coupled plasma emission spectrometry. The results showed that the average mass concentration of collagen peptides Ca, P, and Na derived from fish skin were 14.05, 10.10, and 63.81 mg/kg, respectively, which were higher than those of collagen derived from pig skin and cow skin. The average mass concentration of K in collagen derived from cow skin was 18.67 mg/kg, which was higher than the collagen peptides derived from pig skin and fish skin,the mass concentration distributions of K, Ca, P and Na in collagen peptides from the same source were varied. Collagen peptides differ in elemental composition due to their different sources and preparation processes. When selected as raw materials in the food industry, it is recommended to analyze and batch check mass concentration of certain elements.
