Summary:The invention provides abalone shell source calcium citrate malate and a preparation method thereof. Abalone shell is taken as a raw material, an acid solution is adopted for dissolving out calcium ions and pigment, impurities like the pigment are removed through precipitation and then solid-liquid separation is carried out, calcium ions in filtrate are chelated and precipitated by virtue of a substance containing citrate malate radicals, and drying is carried out, so that calcium citrate malate is obtained. The calcium citrate malate product is soluble in acid, insoluble in alcohol, slightly soluble in alkali and slightly soluble in water, purity of calcium citrate malate is more than or equal to 95.8%, calcium ion content is more than or equal to 20%, citrate malate radical content is more than or equal to 72%, and pigment colour value E496<1%>1cm is less than and equal to 0.58. The preparation method of calcium citrate malate has the advantages that the calcium ions and the pigment can be efficiently disso
