Aqueous stable lysine solution

Abstract

Herein is disclosed an aqueous stable lysine solution containing an acid radical in such amount that the solubility of lysine therein has been increased than in the corresponding aqueous lysine base solution, whereby during storage of lysine in the form of a free-lysine solution (liquid composition), the precipitation of lysine base crystals due to the drop in temperature is prevented thereby improving the handling thereof during transportation (transfer) etc.

1 . An aqueous stable lysine solution containing an acid radical in such amount that the solubility of lysine therein has been increased than in the corresponding aqueous lysine base solution.  
     
     
         2 . The aqueous stable lysine solution as set forth in  claim 1 , wherein the content of the acid radical is 35% or less, in terms of the ratio of the product of the molar number of the acid radical multiplied by its valence to the molar number of the lysine.  
     
     
         3 . The aqueous stable lysine solution as set forth in  claim 1  or  2 , wherein said acid radical is the chloride radical (Cl − ) and/or the sulfate radical (SO 4   2− ).  
     
     
         4 . The aqueous stable lysine solution as set forth in  claim 1 , wherein said acid radical is the chloride radical (Cl − ) and is contained within the range of 35% or less in terms of the molar ratio thereof to the lysine.  
     
     
         5 . The aqueous stable lysine solution as set forth in  claim 1 , wherein said acid radical is the sulfate radical (SO 4   2− ) and is contained within the range of 17% or less in terms of the molar ratio thereof to the lysine.  
     
     
         6 . A lysine-enriched feed and an industrially produced mixed feed wherein the aqueous stable lysine solution described in any one of  claims 1  to  5  has been used.
