1. Edible gelatin.
It is an important ingredient and additive in the food industry and is often used as a gel, stabilizer, emulsifier, thickener and clarifying agent in the production of meat products, cakes, ice cream, beer, juice, etc.
2. Biofilm materials.
The most studied gelatin substrate materials at home and abroad are mainly chitosan-gelatin blending film, gelatin-silk blending film, polylactic acid-gelatin blending film and polyvinyl alcohol-gelatin blending film, etc., these mixed materials greatly improve the physical and chemical properties of gelatin, so that gelatin-based polymer film materials more functional.
3. Medical fiber.
The mechanical properties of gelatin based medical fiber materials were improved by blending filament with other composites and gelatin.
4. Organizational repair and substitution.
Gelatin matrix composites are used as tissue engineering scaffold materials and signal molecular carriers, which is one of the research hotspots of biomaterials at present. The gelatin solution forms hydrogel after crosslinking, in which the water is perforated agent, the porous scaffold material is formed after freeze-drying, and the pore rate and pore size can be adjusted by changing the freezing parameters.
Therefore, according to the requirements of different tissue repair, the ideal gelatin base tissue engineering materials can be designed.
5. Industrial gelatin.
Used in the manufacture of fiber textiles, insulating materials, paper, holographic materials, etc. In industrial glue, people are used to extracting hydrolyzed animal protein protein with glue called protein gelatin, dedicated to feed additives feed glue called feed gelatin, for the match industry matches special glue called match gelatin, as well as for packaging and other products of hot-soluble gelatin called hot sol powder,
The gelatin with natural drying as a dry way is called soil glue.
