氨基酸短肽螯合物及其制备方法
摘要：
本发明提供氨基酸短肽螯合物，其为具有式－[－C8H8O6N2M·X H2O－]n－(I)的天冬氨酸短肽螯合物，或者为具有式－[－C10H12O6N2M·X H2O－]n－(II)的谷氨酸短肽螯合物，其中M选自Ca、Mg、Zn或其他二价过渡金属元素中的一种；n是结构单元数，为5－7；X是水分子数，为0－3。本发明还提供上述氨基酸短肽螯合物的制备方法，该方法包括将氨基酸与金属氧化物、金属氢氧化物或金属碳酸盐在水溶液中螯合，经提纯、精制后在160－260℃高温下缩聚的步骤。用本发明方法制得的产物纯度高、质量稳定、工艺简便、成本适宜、利于规模化、工业化生产，可广泛用于食品、饮料、饲料或化妆品领域。
摘要（英）：

The present invention provides amino acid short peptide chelate, and the amino acid short peptide chelate may be aspartic acid short peptide chelate in the expression of -[-C8H8O6N2M .X H2O-]n- or glutamic acid short peptide chelate in the expression of -[-C10H12O6N2M .X H2O-]n-, where, M is one of Ca, Mg, Zn or other bivalent transition metal elements; n is constructional unit number, 5-7; and X is water molecule number, 0-3. The present invention also provides the preparation process of the amino acid short peptide chelate, and the preparation process includes the steps of chelation of amino acid with metal oxide, metal hydroxide or metal carbonate in water solution, purification, refining and condensation at high temperature of 160-260 deg.c. The products of the present invention have high purity, stable quality, simple preparation process and low cost, is suitable for industrial production, and may be used widely in food, beverage, feed and cosmetics.
