Abstract
Official abstract text for this publication.
The present disclosure relates to a preparation method of a methionine-metal chelate, and the methionine-metal chelate, which is prepared by first reacting Ca(OH) 2 and methionine and adding metal chloride salts, can be used as feeds and feed additives.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for preparing a neutral methionine-metal chelate, comprising: mixing methionine and Ca(OH) 2 ; and adding one or more metal chloride salts to the mixture to produce the neutral methionine-metal chelate, wherein the methionine-metal chelate has structure of Chemical formula 1; wherein M is a metal from the one or more metal chloride salts. 2. The method of claim 1 , wherein the methionine is L-methionine or DL-methionine. 3. The method of claim 1 , wherein metals in the one or more metal chloride salts are one or more metals selected from the group consisting of copper (Cu), zinc (Zn), manganese (Mn), and iron (Fe). 4. The method of claim 1 , wherein the one or more metal chloride salts are added at an equivalence ratio of 0.3 to 3.0. 5. The method of claim 1 , further comprising purifying the produced methionine-metal chelate. 6. The method of claim 1 , wherein the methionine is used in an aqueous methionine solution, and further comprising drying the methionine-metal chelate. 7. A method for preparing calcium chloride (CaCl 2 ), comprising: mixing an aqueous methionine solution and Ca(OH) 2 ; adding one or more metal chloride salts to the mixture to produce a neutral methionine-metal chelate; separating an aqueous solution comprising the neutral methionine-metal chelate and calcium chloride (CaCl 2 ) via filtration to produce a filtrate from which the neutral methionine-metal chelate has been removed; and concentrating the filtrate to obtain calcium chloride (CaCl 2 ); and wherein the neutral methionine-metal chelate has structure of Chemical formula 1; wherein M is a metal from the one or more metal chloride salts. 8. The method of claim 7 , wherein metals in the one or more metal chloride salts are one or more metals selected from the group consisting of copper (Cu), zinc (Zn), manganese (Mn), and iron (Fe). 9. The method of claim 7 , further comprising granulating the calcium chloride after the concentrating.
