Abstract
Disclosed are water-insoluble, calcium or magnesium salts of alpha amino acids and a process for their preparation. The process comprises the steps of reacting an alpha-amino-protected alkyl ester of an amino acid with a metal base, thereby forming a water-soluble amino acid salt, followed by reacting the water-soluble salt with either a calcium or magnesium salt, resulting in the formation of a water-insoluble salt of the amino acid. The water-insoluble salts can be used as feed supplements for ruminant animals and to supplement food products for human consumption.
