Abstract: A process for the purification of optically active lysine monohydrochloride, containing racemic lysine monohydrochloride as an optical impurity, is disclosed. In this process the solid salt is treated with water to effect an at least partial dissolution or extraction of the optical antipod of the lysine monohydrochloride which is present in the original salt. The aqueous solution thus formed is separated from the solid phase before an equilibrium state is reached, the solid phase thus obtained being of lower optical purity than the original salt.

Abstract: There is provided an improvement in the process for increasing the amino acid content of cereals by contacting with an aqueous solution of at least one amino acid to cause absorption of the amino acid into the cereal. The improvement resides in first increasing the water content of the cereal prior to contacting the cereal with the solution of at least one amino acid, whereby an increased absorption of the amino acid is obtained.
