Preparation method of amino acid chelated calcium with abalone shells as calcium source

The invention provides a preparation method of amino acid chelated calcium with abalone shells as a calcium source. The preparation method comprises the following steps: S1, removing impurities on thesurfaces of the abalone shells, then crushing the abalone shells, sieving the crushed abalone shells with a 100-mesh sieve, and placing the sieved abalone shells in a dryer for later use; and S2, mixing the powder obtained in the step S1 with amino acids, adding a certain proportion of distilled water, carrying out ultrasonic stirring, cooling and suction filtration, carrying out vacuum concentration in a rotary evaporator to obtain paste, drying and crushing the paste to obtain amino acid chelated calcium powder, and measuring the chelating rate of the amino acid chelated calcium powder. 本发明提供了一种以鲍鱼壳为钙源的氨基酸螯合钙制备方法，包括以下步骤：S1，对鲍鱼壳表面进行除杂，然后将其粉碎过100目筛，置于干燥器中以备用；S2，将步骤S1中粉末与氨基酸混合，加入一定比例的蒸馏水，超声搅拌，冷却抽滤，于旋转蒸发仪中减压浓缩至膏状，烘干，粉碎，即得氨基酸螯合钙粉末，测定其螯合率。
