  • Method of producing calcium pyruvates
    Patent number: 6342631
    Abstract: A method of producing calcium pyruvates is described, in which calcium salts of organic acids or acidic organic keto or hydroxy compounds are reacted with pyruvic acid at a temperature in the range from −20 to +120° C., if necessary in the presence of a solvent or diluent. In this way, high-purity calcium pyruvates are obtained which can be largely free of water and have a very long shelf life.
