Embodiment 1

[0017] Dilute methionine and ferrous sulfate with 2.5 times of water to prepare an aqueous solution, send the aqueous methionine solution to the chemical reaction kettle, keep the normal temperature, start the agitator, add the aqueous solution of ferrous sulfate in a molar ratio of 2:1, and oxidize it with hydrogen Sodium aqueous solution is used to adjust the pH value so that it is always maintained at about 7.2. React for 0.5 hours. The reactant is sent to a centrifuge for separation to remove water. Add absolute ethanol to the separated solid at a ratio of 1:1, filter off the absolute ethanol for reuse after stirring, and send the remaining ferrous methionine into a dryer to seal and dry, and then crush and pack the dried product to obtain a finished product .

Embodiment 2

[0019] Dilute methionine and copper sulfate with 2.5 times of water to make an aqueous solution, put the aqueous solution of methionine into the chemical reaction kettle, keep the normal temperature, start the stirrer, add the aqueous solution of copper sulfate according to the molar ratio of 2.1:1, and use the aqueous solution of sodium hydroxide Adjust the pH so that it is always around 7. React for 0.5 hours. The reactant is sent to a centrifuge for separation to remove water. The separated solid is added with absolute ethanol at a ratio of 1:1, and after stirring, the absolute ethanol is filtered off for recycling, and the remaining copper methionine is sent to a dryer for sealing and drying, and then the dried matter is crushed and packaged to obtain a finished product.

Embodiment 3

[0021] Dilute methionine and manganese sulfate with 2.5 times of water to make an aqueous solution, put the methionine aqueous solution into the chemical reaction kettle, keep the normal temperature, start the stirrer, add manganese sulfate aqueous solution in a molar ratio of 2.2:1, and use sodium hydroxide aqueous solution Adjust the pH value to keep it around 7.2. React for 0.5 hours. The reactant is sent to a centrifuge for separation to remove water. The separated solid is added with absolute ethanol at a ratio of 1:1, and after stirring, the absolute ethanol is filtered off for recycling, and the remaining manganese methionine is sent to a dryer for sealing and drying, and then the dried matter is crushed and packaged to obtain a finished product.

Abstract

The invention discloses a preparation method of a feed additive-amino acid trace element chelate. The product of the invention is a high-tech feed additive, which contains not only amino acids but also trace elements easily absorbed by animals. The prepared The feed has good palatability, high absorption rate, and is easy to transport. It can strengthen the activity of enzymes in animals, improve the utilization rate of protein, fat and vitamins, and thus improve the growth performance of animals. It is suitable for both animals and fish. The raw materials used in the production of this product are: amino acids (methionine, lysine, L-tryptophan), inorganic salts (ferrous sulfate, copper sulfate, manganese sulfate, zinc sulfate), 10% aqueous sodium hydroxide solution, absolute ethanol .

Description

1. Technical field [0001] The invention belongs to the field of feed, and in particular relates to a method for industrially producing a feed additive-amino acid trace element chelate by using amino acids. 2. Background technology [0002] Trace elements are one of the essential nutrients in the growth process of animals. Initially, trace elements were directly added to the feed in the form of inorganic salts, such as ferrous sulfate, copper sulfate, manganese sulfate, zinc sulfate, calcium iodate, sodium selenite, etc. The trace element additives commonly used in my country's feed industry are still inorganic salts or oxides of trace elements. Although inorganic salts have good water solubility, they are easy to pass through the animal body with phytic acid anions and oxalate anions commonly found in feed in the animal digestive tract. The corresponding biochemical reaction forms form corresponding salts with low solubility, which are not easily absorbed by the intestinal t...
