Problems solved by technology

However, the first and second methods have a significant disadvantage: the protein in the prepared feed is not hydrolyzed into small peptides, which cannot be directly absorbed by the animal's digestive tract, and the biological potency is low; in the third method, there are small peptides , but the content of small peptides is low, the advantages of small peptides cannot be brought into play, and the absorption of feed additives is also poor, so it is impossible to effectively utilize and comprehensively utilize feed additives, and it is also impossible to tap the potential performance of small peptides and feed additives. great waste

Embodiment 1

[0049] Add 650kg of soybean protein, 250kg of lard, and 150kg of soybean oil to 2000kg of water, then add 4kg of emulsifier, control the temperature between 50-60°C, stir, homogenize and refine through a homogenizer, and the pressure is about 25-35MPa, and then Enter the emulsification machine for processing. The rotor speed of the emulsification machine is about 1500r / min. In the reasonably narrow gap between the static grinding plate, the moving grinding plate and the propeller blade, strong and reciprocating hydraulic shearing, friction and centrifugal force are formed. After the combined effect of extrusion, liquid flow collision, etc., it lasted about 120 minutes, and then the material was injected into the enzymatic hydrolysis tank, the pH value was about 7.0, and 1.2kg of neutral protease, 1.2kg of papain, and 1.2kg of lipase were added, and the temperature was controlled. Between 45-60°C, stir at a constant speed for 90 minutes, then add to another reaction tank, add ab...

Embodiment 2

[0051] Put 250kg of soybean oil, 250kg of palm oil, 450kg of soybean meal, and 150kg of plasma protein powder into 2000kg of aqueous solution, then add 8kg of emulsifier, control the temperature at about 30-65°C, stir, and then enter the emulsifier for processing, and the rotor of the emulsifier The rotation speed is about 16000r / min. After the combined effects of strong and reciprocating hydraulic shearing, friction, centrifugal extrusion, and liquid flow collision are formed in the reasonably narrow gap between the stator and the rotor, it takes about 50 minutes. Add the material to the enzymatic hydrolysis tank, add 1.5kg of Bacillus subtilis, 1.5kg of papain, and 1.0kg of bromelain, control the temperature at 60°C, and the pH value is about 7.0, stir at a constant speed for 90 minutes, and then add it to another reaction tank. Add 0.5kg of ferrous sulfate and 0.1kg of vitamin C, stir for 30 minutes, and then dry the semi-finished material to become a powder. The dried produ...

Embodiment 3

[0053] Put 220kg of palm oil, 220kg of soybean oil, 450kg of soybean meal, and 200kg of fish meal into 2000kg of aqueous solution, then add 18kg of emulsifier, control the temperature at about 45-56°C, stir, and enter the high-pressure homogenizer for homogenization, the pressure can be 380MPa The internal adjustment is free, and the material is circulated in the container through the circulation pipe to achieve the purpose of refinement, and then enters the emulsification machine for processing. The rotor speed of the emulsification machine is 2800r / min. After forming strong, reciprocating hydraulic shearing, friction, centrifugal extrusion, liquid flow collision and other comprehensive effects in the reasonably narrow gap between them, it lasted about 70 minutes, and then the materials were added to the enzymatic hydrolysis tank with a pH value of 5.5 -7.5, add bromelain 3.5kg, cellulase 1.0kg, temperature control between 40-60 ℃, enzymatic hydrolysis for 160 minutes, then po...

Abstract

The invention provides three methods for preparing a feed with an enzymatic small peptide-additive complex and the corresponding feed. On the basis of the original conventional feed, an additive capable of forming a coordinating covalent bond with an amino group is added, the vegetable protein and / or the animal protein can be hydrolyzed into a small peptide compound by the action of at least one protease, the small peptide compound contains an amino group having an empty track, and the additive capable of forming the coordinating covalent bond forms a coordination compound with the amino group, so that the additive is more stable, which overcomes the shortcomings of fear of light and oxygen, and deactivation while meets acid and alkali; on this basis, other types of additives can be added,and other types of additives can be formed in the cluster formed by the coordination compound, so that the problem of stability of other types of additives can be solved.

Description

technical field [0001] The invention belongs to the field of feed processing, in particular to a feed with enzymatic hydrolysis of small peptide-additive complexes and a preparation method thereof Background technique [0002] In the prior art, there are three processing methods: 1. Emulsify and homogenize the three feed materials of oil, protein and whey powder, and then dry them to become solid powder; 2. Mix oil, protein, whey powder, feed Additives are emulsified and dried to become feed raw materials; 3. The three feed materials (or one of them) of oil, protein and whey powder are homogenized, emulsified and enzymatically hydrolyzed with enzymes, and then dried. Become a solid powder. [0003] The above process plays a positive role in improving feed processing efficiency, promoting animal digestion and absorption, and improving feed emulsification and solubility. However, the first and second methods have a significant disadvantage: the protein in the prepared feed i...
