鳕鱼皮胶原蛋白肽螯合镁工艺条件探究

Studies on the Reaction Conditions of Producing and Chelate of Collagen Peptide with Mg(Ⅱ)

以鳕鱼皮胶原蛋白肽作为原料,合成了鳕鱼皮胶原蛋白肽螯合镁,运用正交实验优选鳕鱼皮胶原蛋白肽螯合镁最佳实验条件。实验结果表明,鳕鱼皮胶原蛋白肽螯合镁最佳的实验条件是:镁盐与肽质量比为2∶1、反应时间为115 min、pH为7.5以及反应温度为70℃;采用水相合成法制备鳕鱼皮胶原蛋白肽螯合镁,以红外分光光谱对产物进行表征。

The reaction conditions of producing the chelate of collagen peptide with Mg （ Ⅱ ） from the collagen peptide of cod fish were studied. In the experimental procedure of producing the chelate of collagen peptide with Mg （ Ⅱ ）, the optimum condition were as follow： the quality ratio of collagen peptide and copper chloride is 2 ： 1;reactionfime, 115 min;pH 7.5;reaction temperature, 70 ℃. Using the water-phase peptide synthesis about the preparation of the chelate of collagen peptide with Mg （ Ⅱ ） is analyzed by IR spectroscopic methods.
