Problems solved by technology

When the concentration of arginine vitamin drops to a certain value, the concentration of ionized hydrogen ions decreases, and it is difficult to dissolve zinc oxide, resulting in an incomplete reaction. The subsequent process cannot remove the residual zinc oxide in the product, resulting in product yield and purity. decline

Embodiment 1

[0047] Embodiment 1: the preparation of zinc arginine raw

[0048] Add 388Kg of arginine vitamin with a purity of 98% to 2.39t of water, start stirring, then add 218.5Kg of sodium carbonate with a purity of 98%, stir until no more bubbles come out, heat up to 40°C, and then add the purity 369.9Kg of 98% zinc sulfate monohydrate, reacted for 2h, concentrated and spray-dried after the reaction to obtain 853.6Kg of the product.

[0049] The content of arginine vitamin in zinc arginine product was measured to be 43.9%, Zn 2+ 15.3%, Na + 10.7%, SO 4 2- It is 22.3%, the water loss rate at 180°C is 4.2%, and the water loss rate at 104°C is 2.3%, that is, the purity is 96.4%, and the yield is calculated as 99.7% based on arginine, that is, arginine The molar ratio of element to zinc is about 1:1, and the molecular formula is C 6 h 8 N 2 o 5 Zn·H 2 O.

Embodiment 2

[0050] Embodiment 2: the preparation of zinc arginine raw

[0051] Add 388Kg of arginine vitamin with a purity of 98% to 1.5t of water, start stirring, then add 416.8Kg of potassium bicarbonate with a purity of 98%, stir until no more bubbles come out, heat up to 30°C, and then add 598.6 Kg of zinc sulfate heptahydrate with a purity of 98% was reacted for 1.1 h. After the reaction was completed, it was concentrated and spray-dried to obtain 560.0 Kg of the product.

[0052] The content of arginine vitamin in zinc arginine product was measured to be 40.7%, Zn 2+ 14.2%, K + 17.1%, SO 4 2- It is 20.9%, the water loss rate at 180°C is 3.9%, and the water loss rate at 104°C is 2.3%, that is, the purity is 96.8%, and the yield is calculated as 99.8% based on arginine, that is, arginine The molar ratio of element to zinc is about 1:1, and the molecular formula is C 6 h 8 N 2 o 5 Zn·H 2 O.

Abstract

The invention discloses a preparation method and an application of arginine activator additive zinc. The preparation method comprises the following steps: reacting arginine activator additive with carbonate or bicarbonate in water, stirring until no bubbles emerge, carrying out heating, adding inorganic zinc salt, and reacting for a period of time to obtain arginine activator additive zinc. The prepared arginine activator additive zinc is applied as an animal feed additive, and animals are pigs, birds, ruminants or aquatic animals. The preparation method of the arginine activator additive zincis simple in process, low in cost, low in energy consumption, high in yield and high in product quality. The arginine activator additive zinc has the advantages of high biological value, low additionamount, obvious growth promoting effect, few animal side reactions, long-term use, safety, no drug resistance and the like.

Description

technical field [0001] The invention relates to the preparation and application of a feed additive, in particular to the application of an amino acid complex as a feed additive and a preparation method thereof. Background technique [0002] Arginine can participate in the body's urea cycle in animals, has a long half-life, stable metabolism, and has a wide range of biological functions. Studies have shown that arginine can be used as a metabolic activator to participate in the activation of dihydropyrrole-5-carboxylate synthase (P5CS) and carbamyl phosphate synthase I (CPS-I), and promote the activation of glutamine or proline. Acid synthesis citrulline, and then promote the synthesis of arginine, so it is called endogenous activator of arginine. Nitric oxide and polyamines (including putrescine, spermidine and spermine) have a wide range of functions in the living body, can promote local blood circulation, regulate the body's nutritional metabolism and immune response.
