Abstract The technological processing of calcium lactate from egg shells is studied. The optimal conditions are shown as following: the egg shell was reduced to ashes at 900℃ for 110 minutes, then put water (50ml) into ash contents (4g) so as to form limewash, finally, the 14ml 13mol/L lactic acid was added into the limewash and kept at 80℃, after filtration, crystallization and filtration again, the product was dried to white powder. The yield was 75.6% and the content of calcium lactate was 88.1%.
