Definitions
- the present invention relates to a method for producing high-density collagen that is suitable for medical materials, and more particularly, to allow collagen to be produced in various concentrations for use as a medical material, and especially high-density collagen has excellent performance for the purpose. Compared to low concentration, there is an advantage that it is easy to store. In addition, it is a very useful invention to meet the various needs of consumers by improving the quality and reliability of the product.
- collagen is a fibrous protein that is one of the proteins that make up the skin, bones, and tendons. They are especially distributed in connective tissues of the body, and our body contains about 20% protein, of which collagen accounts for about 30%.
- the molecular structure of the collagen has a triple helix structure in which three polypeptide chains are wound and bonded to each other by hydrogen bonds.
- Collagen with this structure has functions such as adhesion of cells, support of body and organs, activation of cell function, cell proliferation, hemostasis, immunity, etc. It is a protein.
- Collagen having such characteristics is currently used as a raw material or additives in various fields, including beauty, health drinks, health foods, medicines and cosmetics, and its functional field is gradually expanding its application field.
- collagen is generally obtained by collecting the bone and leather of cows or pigs, and then separating the collagen from the tissues by using organic solvent extraction, acid / base treatment, trypsin and hyaluronidase to obtain collagen as an insoluble substance. Because of their high molecular weight, digestion and absorption in the human body are difficult and the purity is lowered due to various impurities included in the raw material.
- Collagen is currently known as more than 20 species, collagen type 1 is occupied most, morphologically present in the form of a fibrous solid, three-stranded polypeptide has a structure twisted by hydrogen bonds, molecular weight is about 300kDa.
- Collagen can be dissolved in dilute acid or dilute alkali and prepared in liquid form. The higher the concentration, the higher the viscosity.
- Collagen is suitable for living tissue and is a biodegradable material, so it is widely used as one of medical materials such as tissue repair agent, skin transplant agent, bone graft agent, and cell culture.
- the collagen is generally subjected to conventional filtration.

- collagen is a biodegradable protein that is biodegradable with low antigenicity and extracted from tissues of various animals to obtain such collagen and medical devices and It is widely used as a raw material for cosmetics and food as well as medical materials such as pharmaceuticals.
- low molecular weight substances such as enzymes and sodium chloride, which are widely used in collagen extraction, should be removed to a level suitable for medical use.
- collagen powder is used to manufacture medical collagen products in a high concentration liquid form, it maintains the uniqueness and structure of collagen and cannot be sterilized in a powder state. It takes a long time.
- Mammalian tissue is treated with 70% ethyl alcohol for 24 hours and acidic solution for 72 hours or more to inactivate the virus, and filtered through a 0.22 micrometer pore filter to remove microorganisms to ensure safety.
- the present invention is characterized by extracting high concentration liquid collagen with high purity as a raw material of mammalian tissue for use as a medical material.

- sodium chloride is added to the solution having the enzyme treatment to a concentration of 0.5 to 0.9 M to perform a salt treatment process.
- Each protein has a property of aggregation at a specific salt concentration, and collagen is a process using the property of flocculation and floating at the salt concentration, so that other non-aggregated impurities can be discarded to increase collagen purity.
- the aggregated collagen is dissolved again in purified water to proceed with the filtration process.
- the filter is first filtered using a filter having a pore size of 2.0 to 0.5 micrometers, and low molecular substances such as pepsin and sodium chloride are removed using a tangential flow filtration device (TFF).

To remove about 35 kDa pepsin.
- MWCO molecular weight blocking
- the filtration process using the tangential flow filtration device is composed of a storage tank 11, a pump 12, a filtration membrane 13, a pressure gauge 15, and a valve 14.
- the solution of the storage tank is transferred to the filtration membrane by a pump so that collagen larger than the pores of the filtration membrane is recovered without storage, and impurities smaller than the pores are removed through the pores.
- Purified water is added as much as the capacity removed through the pores of the filtration membrane and the purity can be increased while securing the flowability of the collagen solution in the storage tank (Fig. 1, 2).
- Purification results using a tangential flow filtration device can be confirmed by various methods, among which sodium chloride removal can be confirmed through the osmotic pressure measurement (see Example 3).
- the concentration is higher than 10mg / mL due to the characteristics of collagen, the higher the concentration, the collagen will accumulate in the filtration membrane, and the flowability of the collagen solution will be greatly reduced, resulting in a lower yield and a long process time. do.
- it is concentrated to a concentration of 5 mg / mL or less to ensure flowability and viscosity that can be sterilized by filtration.
- the non-aggregated solution By coagulating the collagen through the neutralization process, the non-aggregated solution can be removed to reduce the concentration of the concentration before concentration using centrifugation, and the concentration can be performed in a short time with low centrifugal force by facilitating the separation of water and collagen. It is possible to build a facility capable of mass production at a relatively low cost.
- the collagen aggregated through neutralization is placed in a sterilizable centrifuge container, and then concentrated using a centrifuge for 5 minutes at a gravity acceleration of 4,000 to 6,000 g.
- the concentrated collagen is put into a mixer having a sealed structure (Fig. 4), and then mixed homogeneously to obtain a high concentration of collagen for use as a medical material.
- the concentration of collagen may be adjusted by adding water from which microorganisms and pyrogenic substances have been removed according to the purpose of application, and high concentration collagen of 120 mg / mL may be obtained under the above conditions.
- the acid solution such as hydrochloric acid
- the pH titration solution in the mixing process and kept at a pH of 1.5 to 5.5
- it can be stored in a homogeneous state for a long time stable. If the pH is too low, it is difficult to titrate the pH neutrally for the manufacture of a product for later medical use, and if the pH is higher than 5.5, the collagen will reaggregate and it will be difficult to maintain a uniform concentration.
- the collagen obtained through the extraction, purification, concentration and mixing process may be mixed and diluted with a mixed solvent such as water, isotonic solution, platelet-rich plasma (PRP), hyaluronic acid and the like to produce a liquid product, depending on the intended use.
- a mixed solvent such as water, isotonic solution, platelet-rich plasma (PRP), hyaluronic acid and the like to produce a liquid product, depending on the intended use.
