Gelatin is a white or light yellowish brown, translucent, slightly shiny flake or powder. It is almost odorless and tasteless. It is soluble in hot water but insoluble in cold water. , but it can slowly absorb water and swell and soften. Gelatin can absorb 5-10 times of water equivalent to its weight.
Gelatin can be used in the following industry fields:
1. Edible gelatin. It is an important ingredient and additive in the food industry and is often used as a gelling agent, stabilizer, emulsifier, thickener and clarifier in the production of meat products, cakes, ice cream, beer, juice, etc.
2. Biofilm materials. The gelatin-based film materials that have been most studied at home and abroad are mainly chitosan-gelatin blend films, gelatin-silk fibroin blend films, polylactic acid-gelatin blend films, and polyvinyl alcohol-gelatin blend films. These mixed materials greatly The physical and chemical properties of gelatin are improved, making the gelatin-based polymer membrane material more functional.
3. Medical fiber. Use other composite materials and gelatin to blend and spin to improve the mechanical properties of gelatin-based medical fiber materials.
4. Tissue repair and replacement. The use of gelatin-based composite materials as tissue engineering scaffold materials and signaling molecule carriers is one of the current research hotspots in biomaterials. The gelatin solution is cross-linked to form a hydrogel, in which water is a porogen. After freeze-drying, a porous scaffold material is formed, and the porosity and pore size can be adjusted by changing the freezing parameters. Therefore, ideal gelatin-based tissue engineering materials can be designed according to different tissue repair requirements.
5. Industrial gelatin. Used in the manufacturing of fiber textiles, insulation materials, paper, holographic materials, etc.
