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.
