摘要：

Crystallization and dissolution behavior of L(+) calcium and zinc lactate in 50% ethanol-water solution was studied. The effects of stirring, standing, ultrasonic wave, and temperature on the crystallization of L(+) calcium and zinc lactate were evaluated. It was found that standing had a positive effect on crystallization of L(+) calcium and zinc lactate, while stirring promoted dissolution of crystallized particles and resulted in high residual concentration in mother liquor. The application of ultrasonic wave did not influence much or. crystallization process. L(+) calcium and zinc lactate crystallized easily at 5degreesC; however, complete crystallization tool: more than 72 hours. These two salts dissolved rapidly and reached equilibrium within 1 hour.
