Embodiment 1
[0016] A kind of method utilizing chicken intestines to prepare chicken intestinal peptides, it comprises the steps:
[0017] (1) Take 3 tons of fresh chicken intestines, heat and mature them at 138°C, collect the mature chicken intestines and the liquid part that flows out during the heating process;
[0018] (2) Squeeze and degrease the cooked chicken intestines, collect the defatted chicken intestines and the liquid part produced during the extrusion and degreasing process;
[0019] (3) The liquid part collected in steps (1) and (2) is separated and removed by a decanter three-phase centrifuge at a speed of 3000rpm to remove the precipitate and grease, and the clear liquid part is collected;
[0020] (4) The clear liquid part in step (3) and the degreased chicken intestines in step (2) are mixed and beaten by meat grinder, colloid mill and other equipment respectively, and the number of beating mesh is 100 mesh;
[0021] (5) Cool the beaten chicken intestines through a pla...
Embodiment 2
[0027] A kind of method utilizing chicken intestines to prepare chicken intestinal peptides, it comprises the steps:
[0028] (1) Take 3 tons of frozen chicken intestines and crush them, heat and mature them at 121°C, collect the matured chicken intestines and the liquid part that flows out during the heating process;
[0029] (2) Squeeze and degrease the cooked chicken intestines, collect the defatted chicken intestines and the liquid part produced during the extrusion and degreasing process;
[0030] (3) Use a disc three-phase centrifuge at 6000rpm to separate and remove the precipitate and grease from the liquid collected in steps (1) and (2), and collect the clear liquid;
[0031] (4) Mix the clear liquid part in step (3) with the degreased chicken intestines in step (2) and beat them with meat grinder, colloid mill and other equipment respectively, and the number of beating mesh is 100 mesh;
[0032] (5) Cool the beaten chicken intestines through a plate frame, control t...

Abstract
A method for preparing chicken intestine peptide from chicken intestines comprises the following steps that firstly, chicken intestines are smashed, heated and cooked, and the cooked chicken intestines and a liquid part flowing out in the heating process are collected; secondly, the cooked chicken intestines are extruded and degreased, and the degreased chicken intestines and a liquid part generated in the extrusion and degreasing process are collected; thirdly, the liquid parts collected in the first step and the second step are separated with a three-phase centrifuging machine to remove precipitate and grease, and a clear solution part is collected; fourthly, the clear solution part in the third step and the degreased chicken intestines in the second step are mixed and pulped; fifthly, the pulped chicken intestines are subjected to enzymolysis with protease; sixthly, after enzymolysis is finished, enzyme deactivation and centrifugation are collected, and clear liquid is collected; seventhly, the clear liquid is packaged and sterilized, and a liquid chicken intestine peptide product, or a solid chicken intestine peptide product is obtained after concentrating and drying the clear liquid.Dry basis main ingredients of the chicken intestine peptide prepared through the technological method include, by weight, larger than or equal to 85% of crude protein, smaller than or equal to 1% of crude fat, larger than or equal to 60% of amino acid and larger than or equal to 50% of peptide.
Description
technical field [0001] The invention relates to a method for preparing chicken intestinal peptides from chicken intestines. Background technique [0002] A large amount of chicken intestines are produced in the process of chicken slaughtering and processing. Except for a very small amount that is used as a dish by humans, most of them are used as bait and fertilizer for feeding catfish, mink, and foxes. The added value of the product is low. Chicken intestines can produce a large number of low molecular weight peptide fragments after being hydrolyzed by protease, and the peptide fragments can be added to feed or pet food to improve the digestion and absorption rate of feed. Some of these small peptides have special biological functions such as immunity and regulation, which can affect the production performance of animals, especially young animals. Small peptides can advance the digestive function of the small intestine by inducing the increase of some enzyme activities in ...
