3-Chloro-1,2-Propanediol Derived Amino Alcohol in Protein Hydrolysates

In model aqueous solutions containing 3-chIoro-l,2-propanediol (arising by the interaction of hydrochloric acid with lipids in protein hydrolysate and ammonia, 3-amino-1,2-propanediol was found as the main reaction product together with smaller amounts of glycerol. The reaction mechanism of formation of these two compounds was outlined and discussed as well as the possibilities of formation of some other amino analogues of glycerol chlorohydrins. 3-Amino-1,2-pro-panediol was also identified in commercially available seasonings (hydrolyzed vegetable protein) being present in concentrations of 30 mg kg-1.
