摘要
对蛋壳为原料制备丙酮酸钙的工艺条件进行了研究 .最佳条件为 :鸡蛋壳在 1 0 0 0℃温度下煅烧 2h ,1g蛋壳粉加 1 0mL水 ,用 6mol/L的丙酮酸 7～ 8mL在 5 0～ 60℃温度下进行中和反应 ,制得产品 ,产率可达 95 %以上 ,丙酮酸钙含量为 87 6%.
The technological processing of calcium Pyruvate form egg shell is studied.The Optimal conditions are shown as follows: the egg shell reduced to ashes at 1000℃ for 2h,then put water(10ml) into ash contents (1g) so as to form linweash,finally,the 7～8 ml 6 mol/L Pyruvatic acid is added into the limewash and kept at 50～60℃,after filtration,the product is dried to yellow powder.The yield is 95%,and the content of Calcium Pyruvate is 87.6%.
