氨基酸微量元素螯合物的生产与应用

研究了以动物蛋白质废弃物（毛发、蹄角、皮革下脚料等）为主要原料，工业化生产复合氨基酸微量元素螯合物和生产工艺、产品在工业生产中的质量控制方法以及产品在鲤、非鲫养殖中的应用效果。研究表明，按本工艺，蛋白原料水解近基酸的转化率高，且氨基酸的种类齐全。由于生产过程中采用了控制氨基酸配体与金属离子摩尔比的中间控制方法，确保了微量元素与氨基酸的螯合效果。养鲤试验表明，添加螯合盐的三个试验组分别比添加无机盐的

Application and production of chelates of amino acids and trace elements

The animal protein waste matter (hair, hoof, hom, leather, etc. ) as the main raw material is used in research. The technological process of cheates of amino acids and trace elements,the prodct of quality control method in industrial production and the application effects of product in common carp, tilapia nilotica feed are investigated. The results show that the technological process is a simple method of prepartion of complex amino acids and trace elements chelates. Amino acids in the product are complete; the chelative effect of trace elements and complex amino acids in the production is good. The comparative experiments of the product with inorganic salt in the culture show the weights of the common carp in the three experimental groups raised by 68. 1%, 46. 9% and 37. 1%; the weights of the tilapia nilotica in the two experimntal groups raised by 75. 8% and 86. 5%, and improved the quality of meat.
