Preparation method for producing small peptide chelated trace elements by utilizing seaweed degradation products and application of small peptide chelated trace elements

The invention discloses a preparation method for producing small peptide chelated trace elements by utilizing seaweed degradation products and application of the small peptide chelated trace elements. Fresh seaweed is used as a raw material and is degraded to generate a seaweed extract of which the main component is small peptide; and chelating the seaweed extract with a copper sulfate pentahydrate aqueous solution, a zinc sulfate heptahydrate aqueous solution, a manganese sulfate monohydrate aqueous solution, a cobalt sulfate heptahydrate aqueous solution and a ferrous sulfate aqueous solution, and carrying out loading by virtue of the action of mesoporous silica microspheres, so as to obtain the small peptide chelated trace element compound. The small peptide chelated trace element compound disclosed by the invention can be used for feed processing, and has good stability and wide market prospect. 本发明公开了一种利用海藻降解产物生产小肽螯合微量元素的制备方法及应用，以新鲜海藻为原料，经降解处理后生成主要成分为小肽的海藻提取物，然后将海藻提取物与五水合硫酸铜、七水合硫酸锌、一水合硫酸锰、七水合硫酸钴、硫酸亚铁水溶液螯
