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 nitrate, can be widely used as feeds and feed additives.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for preparing a methionine-metal chelate, comprising: mixing methionine and Ca(OH) 2 ; and adding metal nitrate to the mixture to produce a methionine-metal chelate. 2. The method of claim 1 , wherein the methionine is L-methionine or DL-methionine. 3. The method of claim 1 , wherein a metal in the metal nitrate is one or more metal selected from the group consisting of copper (Cu), zinc (Zn), and manganese (Mn). 4. The method of claim 1 , wherein the metal nitrate is added at an equivalence ratio of 0.3 or more and 3.0 or less. 5. The method of claim 1 , further comprising purifying the produced methionine-metal chelate. 6. The method of claim 1 , further comprising drying the methionine-metal chelate. 7. A feed or feed additive comprising the methionine-metal chelate prepared by the method of claim 1 . 8. A method for preparing calcium nitrate (Ca(NO 3 ) 2 ), comprising: mixing methionine and Ca(OH)2; adding metal nitrate to the mixture to produce a methionine-metal chelate; separating the produced methionine-metal chelate; and concentrating a filtrate from which the methionine-metal chelate is separated. 9. The method of claim 8 , wherein a metal in the metal nitrate is one or more metal selected from the group consisting of copper (Cu), zinc (Zn), and manganese (Mn). 10. The method of claim 8 , further comprising drying, granulating, or crystallizing after the concentrating. 11. The method of claim 8 , wherein the calcium nitrate is a fertilizer additive.
