PROCESS FOR PRODUCING NOVEL ASCORBIC ACID COMPOUNDS

Abstract The present invention relates to a process of preparing ascorbyl-proline and ascorbly-lysine compound, comprising the steps of: a) converting a L-ascorbic acid to 6-deoxybromoascorbate; b) reacting the 6-deoxybromoascorbate with proline and lysine to form ascorbyl-proline and ascorbly-lysine compound; and c) isolating the ascorbyl-proline and ascorbly-lysine compound, wherein the 6-deoxybromoascorbate is covalently linked to the proline and lysine.
