Abstract
Egg shell was taken as raw materials and the ultrasonic-assisted preparation technology was used to prepare calcium lactate.The single factor experiment and three factors and three levels orthogonal experiment were adopted to study the effects of such factors as solid-liquid ratio,acid-liquid ratio,ultrasonic frequency and time on calcium lactate preparation rate and purity.The optimal technological condition of calcium lactate from egg shell by ultrasonic was determined.The optimal technological parameters of calcium lactate from egg shell should be as follows:solid-liquid ratio 1∶12,acid-liquid ratio 1.4∶1,ultrasonic frequency 400 W,ultrasonic time 25 min,and under such conditions,the preparation rate of calcium lactate is 88.02% ± 2.07%,the purity of calcium lactate is 81.92% ± 0.09%.After removing impurities,the last purity of calcium lactate is 97.18% ± 0.11%.The preparation time of calcium lactate from egg shell was shortened 75% by using the ultrasonic-assisted preparation technology than neutralized directly.The production efficiency was improved significantly.关键词
