摘  要：
为进一步开发鸡蛋壳资源,以废弃的鸡蛋壳为原料,采用超声波辅助法制备柠檬酸钙,探讨了柠檬酸质量比、料液比、超声时间、反应温度、反应时间对鸡蛋壳柠檬酸钙得率的影响;在单因素优化基础上,采用响应面法研究各自变量及其交互作用对柠檬酸钙得率的影响。结果表明,鸡蛋壳制备柠檬酸钙的最适工艺条件为:超声时间22.0min,反应温度61.2℃,反应时间37.0min,料液比为1∶30,柠檬酸质量比为1∶1.6。此条件下柠檬酸钙得率达79.29%±1.67%。超声波辅助与常规方法相比,耗能较少,得率较高,且试验结果与预测模型相近。此工艺下鸡蛋壳柠檬酸钙得率良好,成本较低,且杂质较少。本研究为以鸡蛋壳为钙源进行柠檬酸钙生产提供了技术参考。

摘  要：
In this paper,for further development of egg shell resource,waste eggshells was taken as raw material,research of calcium citrate preparing was carried out by using ultrasonic-assisted extraction on the key factors such as mass percentage of citric acid,solid-liquid ratio,ultrasonic time,reaction temperature and reaction time related to the yield of calcium citrate. Based on the single factor optimization,the influence of the variables and their interaction on the yield of calcium citrate was studied by using Box-Behnken design method. Results proved that the parameters of calcium citrate preparation optimal conditions are as follows: ultrasonic for 22 minutes,react 37 minutes under the temperature of 61. 2℃,solid-liquid ratio of 1∶ 30,mass percentage of citric acid is 1∶ 1. 6. Under this optical condition,the yield of calcium citrate from eggshells can reach 79. 29% ± 1. 67%. Compared with the traditional reaction method,this ultrasonic assisted reaction method expending less energy,have higher yield of calcium citrate,and results are closer to prediction model,can be used as an effective method for preparing calcium citrate from eggshells. The present method gives an acceptable yield and improved quality of calcium citrate. And this study could be helpful for the production or manufacture of calcium citrate based on eggshell as calcium resources.
