Problems solved by technology

[0006] Although protein can absorb a lot of protein from the diet, due to time, cooking methods and other reasons, it is difficult to supplement the required protein in a convenient and timely manner.
In addition, although meat rich in animal fat can provide protein, it will also bring many disadvantages. For example, it contains harmful substances such as excessive saturated fat, cholesterol, concentrated hormones, and antibiotic residues, which can easily lead to increased body fat cholesterol and Other health risks, leading to cardiovascular disease, etc.

Embodiment 1

[0070] A preparation method of collagen peptide, comprising the following steps:

[0071] (1) Raw material pretreatment

[0072] The cowhide was cut into small pieces, and at 5°C, the mass fraction was 5% Na 2 CO 3 Degreasing with aqueous solution for 18 hours to obtain degreased cowhide; rinse with 12 times (based on the mass of cowhide, the same below) NaCl solution with a mass fraction of 5% to remove salt-soluble non-collagen components; rinse with distilled water to obtain cowhide particles, and refrigerate at -20°C for later use ;

[0073] (2) Water extracted collagen

[0074] Add cowhide particles to 25 times distilled water, stir and extract at 75°C, collect by filtration every 6 hours and replace hot water, extract until the cowhide is completely dissolved, filter, collect the filtrate, centrifuge, and freeze-dry to obtain collagen samples;

[0075] (3) Preparation of collagen peptides by enzymatic hydrolysis

[0076] Prepare a concentration of 0.6mol / L acetic ac...

Embodiment 2

[0078] A preparation method of collagen peptide, comprising the following steps:

[0079] (1) Raw material pretreatment

[0080] The cowhide was cut into small pieces, and at 2°C, the mass fraction was 2% Na 2 CO 3 Degreasing with aqueous solution for 15 hours to obtain degreased cowhide; washing with 10 times (based on the mass of cowhide, the same below) NaCl solution with a mass fraction of 2% to remove salt-soluble non-collagen components; rinsing with distilled water to obtain cowhide particles, and refrigerating at -10 for later use;

[0081] (2) Water extracted collagen

[0082] Add cowhide particles to 20 times distilled water, stir and extract at 60°C, collect by filtration every 4 hours and replace hot water, extract until the cowhide is completely dissolved, filter, collect the filtrate, centrifuge, freeze-dry, and obtain collagen samples;

[0083] (3) Preparation of collagen peptides by enzymatic hydrolysis

[0084] Prepare a concentration of 0.2mol / L acetic ac...

Embodiment 3

Abstract

The invention belongs to the technical field of protein preparation, and particularly relates to a preparation method and an application of collagen peptide. The preparation method of the collagen peptide comprises the following steps: (1) pre-treating raw materials; (2) extracting collagen with water; and (3) preparing collagen peptide by an enzymolysis method, and the like. The prepared collagenpeptide can be prepared into a protein bar, the preparation method is simple, and the prepared protein bar has good nutrition, taste and stability and is suitable for athletes to eat.

Description

technical field [0001] The invention belongs to the technical field of protein preparation, and in particular relates to a preparation method and application of collagen peptides. Background technique [0002] After studying the exercise habits and characteristics of sports people, it is found that all kinds of sports have a certain degree of damage to the body's joints. In China, the repair of cartilage after joint damage is usually medical treatment. At the same time, the treatment of articular cartilage damage is a difficult problem in the field of orthopedics. Because articular cartilage has no blood vessels, nerves and lymphatic tissue, its repair ability is limited. The normal articular surface is covered by hyaline cartilage. Once the hyaline cartilage is damaged, it will cause joint pain, instability and stiffness, accelerate joint degeneration, and lead to the occurrence of osteoarthritis. Foreign scholars have reported that the incidence of articular cartilage dama...
