Description

TECHNICAL FIELD

[0001] The utility model relates to a collagen peptide production device, and especially to a collagen peptide production device which produces collagen with most molecular weight less than 1000 Dalton and average molecular weight between 500 and 800. BACKGROUND

[0002] Proteins are high-molecular organic compounds composed of carbon, hydrogen, oxygen, nitrogen and other four elements, and a small amount of sulfur and a smaller amount of iodine. The smallest unit of protein is amino acid, which mainly provides the nutrients required for human growth, development, maintenance and cell renewal, and provides the heat energy required by the human body. Collagen peptides are produced by hydrolysis, enzymolysis and other processes of animal tissue skin or bone, fish scales and fish skin, which can increase the nutritional properties of proteins, prevent these materials from rotting, increase the absorption degree of the human body, remove bad smell and other effects.

[0003] Commercially available collagen is mainly extracted from animal leather or bone, and its original molecular weight is basically more than 300,000 Da (Dalton). However, these proteins are composed of a large number of amino acids. Such high molecular weight must be decomposed into amino acids by gastric acid, otherwise it is difficult to be rapidly absorbed in the body. After decomposition by gastric acid, there is no difference between amino acids and other proteins, that is, the effect of collagen cannot be shown. SUMMARY

[0004] The utility model provides a collagen peptide production device, which aims to produce collagen with most molecular weight less than 1000 Dalton and average molecular weight between 500 and 800.

[0005] To achieve the above purpose, the present application is realized by the following technical scheme:

[0006] The utility model relates to a collagen peptide production device, which comprises: a pretreatment unit for washing untreated raw materials and producing pretreated raw materials; a hydrolysis unit for performing a hydrolysis and cell wall breaking treatment process on the pretreated raw materials by hot water to molecularize the pretreated raw materials and form hydrolyzed raw materials; an enzymolysis unit for adding a compound enzyme to the hydrolyzed raw materials after dewatering and concentration to perform enzymolysis and produce enzymolyzed raw materials; and a post-treatment unit for sterilizing and drying the enzymolyzed raw materials after obtaining the enzymolyzed raw materials to make the enzymolyzed raw materials into a collagen peptide finished product.

[0007] In one embodiment of the present application, the collagen peptide production device further comprises a conveying unit connected to the pretreatment unit, the hydrolysis unit, the enzymatic hydrolysis unit, and the post-treatment unit, for conveying the untreated raw material, the pretreated raw material, the hydrolyzed raw material, the enzymatically hydrolyzed raw material, and the collagen peptide product.

[0008] In one embodiment of the present application, the pretreatment unit further comprises a water washing process for cleaning the surface of the untreated raw material, and a soaking acid process or a soaking alkali process according to the properties of the untreated raw material.

[0009] In one embodiment of the present application, the soaking acid process is performed when the untreated raw material is a fish skin raw material, a fish scale raw material, a pig skin raw material, or the like.

[0010] In one embodiment of the present application, the soaking acid process uses acid substances such as hydrochloric acid, sulfuric acid, phosphoric acid, acetic acid, and citric acid.

[0011] In one embodiment of the present application, the soaking alkali process is performed when the untreated raw material is a cow skin raw material, a cow bone raw material, or the like.

[0012] In one embodiment of the present application, the soaking alkali process uses alkali substances such as sodium hydroxide, calcium hydroxide, and ammonia water.

[0013] In one embodiment of the present application, the hydrolysis and cell wall breaking process immerses the pretreated raw material in hot water at a temperature of 50-70°C for 5-30 hours.

[0014] In one embodiment of the present application, the complex enzyme is obtained by fermentation of plant proteins such as vegetables and fruits.

[0015] In one embodiment of the present application, the post-treatment unit sterilizes the enzymatically hydrolyzed raw material by high-temperature sterilization at a temperature of 180°C for 10 seconds, and then dries the material to a water content of less than 5%, thereby obtaining the collagen peptide product.

[0016] The present application has the effect that different raw materials are treated in different ways, which is the first step in producing collagen peptides. The original collagen protein is dissociated from the triple helix by acid or alkali treatment, and then the original collagen protein with a molecular weight of about 300,000 is decomposed into hydrolyzed collagen protein with a molecular weight of about 30,000-50,000 by a hydrolysis process (extraction). The molecular weight of the hydrolyzed collagen protein is further decomposed into collagen peptides by special digestive enzymes, so that the molecular weight of the produced collagen peptides is less than 1,000 daltons, and the average molecular weight is between 500 and 800.
