ABSTRACT:
Hydrochloric acid, sulfuric acid or an L-lysine solution having an equivalent ratio of anion/L-lysine higher than 0.95 is added to a raw material L-lysine solution having an equivalent ratio of anion/L-lysine lower than 0.68 to adjust the equivalent ratio of anion/L-lysine of the raw material solution to be in the range of 0.68 to 0.95, and the obtained L-lysine solution or a concentrate thereof is granulated and dried to obtain a dry granulated product having a high L-lysine content and showing low caking property and low hygroscopic property.
