Carrageenan (also known as antelope gum or carrageenan) is a kind of natural polysaccharide hydrophilic gum extracted from Marine plant red algae. It is usually white to pale yellow powder, odorless and tasteless.Carrageenan solubility in water is very good, good water temperature at 80 â?? can dissolve, the formation of the gel is thermal reversible gel, namely heating cooling gel melt into solution, solution to form a gel.Carrageenan has good stability, neutral and alkaline conditions, even heating is not easy to hydrolyze.Carrageenan and konjac gum, locust bean gum, xanthan gum, colloidal common use, and can play a significant synergistic effect, and can significantly change the gel characteristics, greatly increase the elasticity of the gel and water retention. Carrera is widely used in food industry, medicine, daily chemical industry, biochemistry, architectural coating, fabric printing and agriculture, etc.
