Embodiment 1

[0050] In a 2000L reaction kettle, add 1500kg of deionized water and 146kg of lysine, stir and dissolve quickly, pump 132kg of 99% cinnamaldehyde (molar ratio 1:1), react for 60 minutes, cool and crystallize, and centrifuge to obtain light yellow lysine. Amino acid cinnamaldehyde lysine Schiff base 260kg, detected by liquid chromatography (standard samples purchased from the United States sigma company) cinnamaldehyde lysine Schiff base content: 94.3%, yield 94.3% or more.

[0051] Infrared spectrum detection of cinnamaldehyde and cinnamaldehyde lysine Schiff base, the results are shown in figure 1 and figure 2 , figure 1 is the infrared spectrum of cinnamaldehyde lysine Schiff base, figure 2 Infrared spectrum of cinnamaldehyde.

[0052] And the cinnamaldehyde lysine Schiff base is carried out to gas chromatography-mass chromatography detection, the results are shown in image 3 , image 3 It is the GC-MS spectrum of cinnamaldehyde lysine Schiff base. Depend on image...

Embodiment 2

[0054] The 260kg cinnamaldehyde lysine Schiff base and maltodextrin 50kg mixed granulation that embodiment 1 produces, contain the granule 310kg of cinnamaldehyde lysine Schiff base, use 8% polyacrylic acid resin in coating vulcanized bed Carry out coating with 16% monoglyceride stearate, 2% polyethylene glycol ethanol solution, three kinds of coating materials allow particle weight gain 6%, obtain coating cinnamaldehyde lysine Schiff base particle 328kg, menses The content of cinnamaldehyde lysine Schiff base detected by phase chromatography (the standard sample was purchased from Sigma, USA) was 74.7%.

Embodiment 3

[0056] In a 2000L reactor, add 1500kg of deionized water and 146kg of lysine, stir and dissolve quickly, pump 132kg of 99% cinnamaldehyde (molar ratio 1:1), and react for 60 minutes to obtain lysine Schiff containing cinnamaldehyde The reaction solution of alkali, wherein, contains cinnamaldehyde lysine Schiff base 260kg in the described reaction solution.

[0057] Slowly pump 300 kg of an aqueous solution containing 125 kg of copper sulfate pentahydrate into the cinnamaldehyde lysine Schiff base reaction solution prepared above, maintain pH 7.2-7.5, and react for 1.5 hours. A large amount of green precipitates are formed, which are centrifuged and dried to obtain 300kg cinnamaldehyde lysine Schiff base copper compound.

Abstract

The invention provides an amino acid aldehyde Schiff base feed additive. The amino acid aldehyde Schiff base feed additive comprises one or more of amino acid aldehyde schiff base and metal compoundsthereof. The amino acid aldehyde Schiff base feed additive has stable properties, has better antibacterial, antifungal and antiviral effects than aldehyde substances, and can effectively prevent feedmildews, prevent and resist mildews, and adsorb and destroy mycotoxins. The feed additive is hydrolyzed in the stomach and the intestine of an animal body under the action of hydrochloric acid in gastric juice to generate amino acids and aldehyde substances which perform respective physiologic and antibacterial effects. Additionally, the amino acid aldehyde Schiff base feed additive also can prevent and treat animal diseases, promote the growth of animals, increase the feed conversion rate, enhance the immunity of the animals, improve the lean meat percentage of the animals, reduce fat deposition and improve the flavor of meat.

Description

technical field [0001] The invention belongs to the technical field of feed additives, in particular to an amino acid aldehyde Schiff base feed additive. Background technique [0002] Feed additives refer to small or trace substances added during feed production, processing and use, which are used in small amounts but have significant effects in feed. Feed additive is an inevitable raw material used in the modern feed industry. It has obvious effects on strengthening the nutritional value of basic feed, improving animal production performance, ensuring animal health, saving feed cost, and improving animal product quality. [0003] Aldehydes, especially cinnamaldehyde, is a commonly used feed additive. Adding it to feed has good antibacterial effect, but aldehydes are easy to oxidize and polymerize, and low boiling point aldehydes are easy to volatilize and are very unstable. Contents of the invention [0004] In view of this, the technical problem to be solved by the pres...
