TH64988A - The product is dry granular containing L-lysine. As the main ingredient - Google Patents

Abstract

DC60 (21/03/46) hydrochloric acid, sulfuric acid or L-lysine solution. Anion / L-lysine equivalent rate higher than 0.95 was added to the raw material L-lysine solution. With the equivalent rate of Anion / L-lysine is lower than 0.68 so that the fermentation solution will have an equivalent rate of anion. / L-lysine of the raw material solution to the range of 0.68 to 0.95, and the derived L-lysine solution or its concentrate was granulated and dried to obtain a granular product. Dry with high L-lysine content and low coagulation properties and exhibit low hygroscopicity, hydrochloric acid, sulfuric acid or L-lysine solution. Anion / L-lysine equivalent rate higher than 0.95 was added to the raw material L-lysine solution. With the equivalent rate of Anion / L-lysine is lower than 0.68 so that the fermentation solution will have an equivalent rate of anion. / L-lysine of the raw material solution to the range of 0.68 to 0.95, and the derived L-lysine solution or its concentrate was granulated and dried to obtain a granular product. It is dry with high L-lysine content and has low coagulation properties and shows low hygroscopicity.
