Embodiment 1

[0034] A method for preparing gradient collagen and collagen polypeptide molecules, specifically comprising the following steps:

[0035] S1. Prepare raw materials: collect fresh animal skins, wash and slice them for later use;

[0036] S2. Degreasing treatment: degreasing the cut animal skin fragments to obtain degreasing animal skin; wherein, the process of degreasing treatment is as follows: put the animal skin fragments into a clean cooking pot, add 3 times the amount of animal skin Deionized water with the mass of fragments is heated to 50°C, and boiled for 20 minutes under the action of ultrasound, and the animal skin fragments are taken out to obtain fat-free animal skin.

[0037] S3. Deodorization treatment: spray the degreased animal skin with ozone water first, and then perform deodorization treatment; wherein, the ozone concentration of the ozone water spray is 1.0 mg / L, and the ozone water spray time is 2 minutes. The process of the deodorization treatment is as f...

Embodiment 2

[0048] A method for preparing gradient collagen and collagen polypeptide molecules, specifically comprising the following steps:

[0049] S1. Prepare raw materials: collect fresh animal skins, wash and slice them for later use;

[0050] S2. Degreasing treatment: degreasing the cut animal skin fragments to obtain degreasing animal skin; wherein, the process of degreasing treatment is as follows: put the animal skin fragments into a clean cooking pot, add 3.2 times the amount of animal skin Deionized water with the mass of fragments is heated to 50° C., steamed for 25 minutes under the action of ultrasound, and animal skin fragments are taken out to obtain degreased animal skin.

[0051] S3. Oxygen removal treatment: the degreased animal skins are first sprayed with ozone water, and then deodorized; wherein, the ozone concentration of the ozone water spray is 1.5 mg / L, and the ozone water spray time is 2 minutes. The process of the deodorization treatment is as follows: soak th...

Embodiment 3

[0062] A method for preparing gradient collagen and collagen polypeptide molecules, specifically comprising the following steps:

[0063] S1. Prepare raw materials: collect fresh animal skins, wash and slice them for later use;

[0064] S2. Degreasing treatment: degreasing the cut animal skin fragments to obtain degreasing animal skin; wherein, the process of degreasing treatment is as follows: put the animal skin fragments into a clean cooking pot, add 3.5 times the amount of animal skin Deionized water with the quality of fragments is heated to 55° C., boiled for 25 in under the action of ultrasound, and animal skin fragments are taken out to obtain degreased animal skin.

[0065] S3. Deodorization treatment: spray the degreased animal skin with ozone water first, and then perform deodorization treatment; wherein, the ozone concentration of the ozone water spray is 2.0 mg / L, and the ozone water spray time is 2.5 min. The process of the deodorization treatment is as follows:...

Abstract

The invention discloses a preparing method of gradient collagen and collagen polypeptide molecules. The preparing method particularly comprises the steps of defatting, deodorizing, primary enzymolysis, secondary enzymolysis and the like. The invention further discloses application of the gradient collagen and collagen polypeptide molecules. The gradient collagen and collagen polypeptide moleculescan be applied to the fields of cosmetics, skin care products, nourishing and health products, food additives, feed and the like. According to the preparing method of the gradient collagen and collagen polypeptide molecules, animal skins are subjected to procedures such as defatting, deodorizing, primary enzymolosis and secondary enzymolysis to be prepared into the collagen and collagen polypeptide molecules with different molecular weights, the procedures are simple, the enzymatic hydrolysis degree of collagen is increased, and thus products are smaller in molecular weight and easy to absorbby the human body. The preparing method of the gradient collagen and collagen polypeptide molecules has good defatting, deodorizing and decolorizing effects and facilitates improvement of the qualityof the products; the whole technology process is simple and reasonable, the safety is high, the operability is high, and the products are high in yield and good in quality.

Description

technical field [0001] The invention relates to the technical field of collagen preparation, in particular to a preparation method and application of gradient collagen and collagen polypeptide molecules. Background technique [0002] Collagen has important physiological functions in the human body, including growth and development of the body, renewal of aging tissues, repair of damaged tissues, regulation of osmotic pressure, maintenance of exchange and balance between plasma and interstitial fluid, etc. Collagen is a protein with a three-dimensional helical structure, which is the strong backing of the dermis of the skin. The skin is supple, smooth and elastic. Wrinkles, aging, looseness, stains, etc. are all due to the holding of collagen and loss caused. [0003] There are about 30 types of collagen, and the common types are type I, type II, type I, type IV, type V and type XI. Collagen is widely used in food, medicine, tissue engineering, cosmetics and other fields du...
