Bovine bone collagen peptide and production method thereof

Abstract

The invention belongs to the field of collagen peptide, and discloses bovine bone collagen peptide and a production method thereof. The production method of the bovine bone collagen peptide comprisesthe steps of impurity removal, smashing and cooking on bovine bone, oil-water separation for cooking liquid, high-efficiency compounding of enzymic preparations, enzymolysis on the condition that thepH value is not adjusted and the temperature condition is not controlled, filtering of an inorganic nanofiltration ceramic membrane to remove components which are easily dissolved and components whicheasily absorb moisture, high-temperature and high-pressure treatment, concentration and drying for powder preparation. According to the method, the enzymolysis pH value does not need to be adjusted,the enzymolysis temperature does not need to be controlled, the enzymolysis time is short, the enzyme addition amount is small, and the enzymatic products are low in molecular weight and are centralized; meanwhile, the prepared bovine bone collagen peptide powder is excellent in water re-dissolubility, and does not easily absorb moisture or get caked in the storage process.

Description

technical field [0001] The invention belongs to the field of collagen peptides, in particular to a bovine collagen peptide and a production method thereof. Background technique [0002] Collagen is rich in amino acids such as glycine, proline, and hydroxyproline that the human body needs. Collagen is a high-molecular functional protein. It is the main component of the skin, accounting for 80% of the skin's dermis. It forms a fine elastic network in the skin, which firmly locks moisture and supports the skin. Collagen is a helical fibrous protein twisted by three peptide chains. It is also the most abundant protein in the human body. It is widely distributed in connective tissue, skin, bone, interstitial cells of internal organs, muscle cavity, ligament, sclera and other parts. Accounting for more than 30% of the total protein in the human body, it is rich in proline, hydroxyproline and other collagen characteristic amino acids needed by the human body, and is an important c...

Problems solved by technology

[0006] However, the problems and shortcomings of the above two invention patent applications are: the enzymatic hydrolysis efficiency of the enzyme used is low, the enzymatic hydrolysis time is long, the amount of enzyme added is large, the optimum pH value and optimum temperature need to be adjusted for enzymatic hydrolysis, and the operation is complicated , adjusting the optimum pH value of enzymolysis will bring in a large amount of inorganic ions, and controlling the optimum enzymolysis temperature consumes a lot of energy; two membrane filtrations with ultrafiltration membrane and nanofiltration membrane are required, and the role of ultrafiltration membrane is as follows: To intercept macromolecular substances, the function of nanofiltration membrane is desalination and concentration, the steps are cumbersome, and the membrane core used is organic material, which is not resistant to acid and alkali, high temperature and high pressure, small flux, short service life, and inconvenient cleaning; , the water resolubility of the prepared collagen peptide powder is poor, and it is easy to absorb moisture and agglomerate during storage
