制备

1.大米经高压糊化，用水稀释冷至50-53℃，接入黑曲霉菌和德氏乳酸杆菌，发酵得到代谢产物乳酸，然后加入磷酸钙中和，得到粗乳酸钙，最后再进行精制，或者用碳酸钙中和稀乳酸液，再将溶液蒸发而制得。精制过程是利用氯化镁和氢氧化钙作用生成的氢氧化镁，它有凝聚作用的性质，使发酵液中的部分杂质和蛋白质凝聚后除去，然后经真空浓缩，结晶，精制而得乳酸钙。（1）发酵法。以碳酸钙为中和剂进行乳酸发酵，用石灰水中和发酵液后经二次结晶，直接生产乳酸钙。发酵原料可用大米糊化糖化液或米粉（玉米粉）双酶水解液，具体参考乳酸发酵。
(2)中和法。在50%的成品乳酸溶液中加入氢氧化钙或氧化钙进行中和反应，然后过滤除去不溶性杂质，再经过冷却结晶、分离、干燥得成品。此法工艺简单，但成本较高。发酵法
