Problems solved by technology

[0004] With the vigorous development of the edible chicken breeding industry, the annual growth rate of the output of chicken viscera has reached more than 10%. Therefore, the deep development of chicken viscera will solve the problem of the deep development of edible chicken slaughterhouses; chicken viscera is used as domestic pet cats and dogs Feed raw materials have been widely used, but most feed factories have a very simple treatment method for chicken viscera: they are used as feed after cleaning, crushing, and drying. This method of processing chicken viscera has great disadvantages: (1) Chicken viscera The internal organs are processed in a simple way, and some bacteria and viruses remain in the raw materials. After eating by cats or dogs, it is easy to cause the occurrence of parasites or diseases; (2) chicken internal organs contain a large amount of indigestible substances and useless substances. After eating, the burden on the digestive organs has been increased, and the diseases of the animal digestive organs have been caused for a long time; (3) the active ingredients in the chicken viscera cannot play a role, especially the chicken viscera contains immune proteins, amino acids, etc., which cannot fully exert its effect, resulting in waste of resources
[0005] Chinese patent application No. 200910099838.x discloses the production process of chicken intestinal peptide. This process obtains chicken intestinal peptide containing 3-methyl indole and amino acids through enzymatic hydrolysis and other methods, because it contains 3-methyl indole Thereby, animals can be induced to eat feed. Although this patent has carried out in-depth development of chicken intestines, it has the following disadvantages: (1) the composition in the chicken viscera is lost, and the chicken viscera contains more than 15 kinds of amino acids, but the chicken viscera obtained by this method There are only 10 kinds of amino acids in intestinal peptides; chicken viscera contains important active ingredients-polypeptides, which cannot be obtained by this process; (2) Adding chemical components: In order to maintain the content of 3-methyl indole in this process, chemical components are added to resist The oxygen agent BHA has potential dangers to animal safety; (3) Ineffective ingredients have not been removed, such as animal fat ingredients, which are not easy to digest for pet cats and pet dogs, and can bring some diseases

Embodiment 1

[0038] Take 10 kg of cleaned chicken viscera, add pepsin at 40°C, stir, keep warm for 3 hours, add organic solvent ethanol, mix, let stand for 2 hours, and separate the supernatant (recover the ethanol from the ethanol layer until it is exhausted, and the remaining discard), filter, and the filtrate is ultrafiltered through a molecular weight cut-off 6000 ultrafiltration membrane, and the permeate is retained, concentrated, and dried to obtain 6.43 kilograms of feed.

[0039] The above feed contains: 35.5% by weight of polypeptide and 60.84% ​​by weight of amino acid. Aspartic Acid 1.3%, Glutamic Acid 10.4%, Threonine 2.9%, Arginine 2.4%, Proline 3.1%, Valine 0.04%, Isoleucine 3.0%, Phenylalanine 3.2% , Lysine 5.7%, Serine 3.3%, Glycine 2.6%, Histidine 1.8%, Alanine 5.7%, Cystine 1.4%, Methionine 6.8%, Leucine 5.2%, Tyrosine 2.0%.

Embodiment 2

[0041] Get 3 kilograms of cleaned chicken internal organs, add pepsin under the condition of 25 ℃, stir, keep warm for 2 hours, add organic solvent carbon tetrachloride, mix, leave standstill for 2 hours, separate the supernatant (carbon tetrachloride layer Recover the solvent until exhausted, discard the residue), filter, and filter the filtrate through an ultrafiltration membrane with a molecular weight cut-off of 5000, retain the permeate, concentrate, and dry to obtain 1.88 kg of feed.

[0042] The above feed contains: 31.3% by weight of polypeptide and 58.604% by weight of amino acid. Among amino acids, aspartic acid 1.2%, glutamic acid 10.0%, threonine 2.55%, arginine 2.1%, proline 3.03%, valine 0.024%, isoleucine 2.91%, phenylalanine 3.11%, Lysine 5.63%, Serine 3.21%, Glycine 2.43%, Histidine 1.72%, Alanine 5.61%, Cystine 1.30%, Methionine 6.72%, Leucine 5.13%, Tyrosine 1.93%.

Embodiment 3

[0044]Take 1 kg of cleaned chicken viscera, add pepsin at 50°C, stir, keep warm for 5 hours, add the organic solvent petroleum ether, mix, let stand for 3 hours, and separate the supernatant (petroleum ether layer recovers petroleum ether to The residue is discarded), filtered, and the filtrate is ultrafiltered through a molecular weight cut-off 5000 ultrafiltration membrane, and the permeate is retained, concentrated, and dried to obtain 0.625 kg of feed.

[0045] The above feed contains: polypeptide weight content 34.7%, amino acid weight content 59.93%, aspartic acid 1.25%, glutamic acid 10.34%, threonine 2.91%, arginine 2.25%, proline 3.03%, valine Acid 0.03%, Isoleucine 2.96%, Phenylalanine 3.13%, Lysine 5.67%, Serine 3.28%, Glycine 2.50%, Histidine 1.73%, Alanine 5.62%, Cystine 1.40%, Methionine 6.71%, Leucine 5.15%, Tyrosine 1.97%.
