Abstract

The invention provides a method for preparing an eel swimming bladder collagen-chitosan-composite sodium alginate hydrogel. The optimal conditions for extracting the collagen of the sea eel swimming bladder by the acid method through a single factor test and response surface optimization are as follows: the acetic acid concentration is 0.42 mol / L, the acidolysis time is 21h, and the liquid-material ratio is 58ml / g. The acid-soluble collagen separated from the sea eel swimming bladder can be used as a proper drug carrier system, is a good medicinal biological material, has a unique porous fiber structure, can be used for absorbing a large amount of water and supporting the skin surface, and has important effects on moisturizing and wrinkle resistance; the collagen can be used as a wound excipient or a drug carrier, has a healing promoting effect on a mouse skin wound, and has huge application potential in biomedical engineering and medicine.

Description

technical field

[0001] The invention belongs to the field of biological extraction, in particular to the preparation of eel swim bladder collagen-chitosan-composite sodium alginate hydrogel Background technique

[0002] The skin is the largest sensory organ in the human body, and it is prone to accidental damage during work. During wound healing, a complex combination of epithelial tissue regeneration, granulation tissue formation and hyperplasia, and scar connective tissue formation is required. Collagen deposition and blood vessel formation are key factors. Key to wound healing. Traditional wound dressings mainly use natural fiber materials such as absorbent cotton gauze and gauze strips, which can dry the wound and provide physical isolation. However, it is easy to tear the wound when changing the dressing, causing re-bleeding, which is not conducive to healing.

[0003] The eel industry in my country has developed tremendously. The eel meat is delicious and has high nut...
