Name :Carrageenan Other name :Chondrus ocellatus .CAS:9000-07-1.
Summary: Carrageenan (Carrageenan) initially originated from Carla root county in the south of Ireland.In the 18th century began to industrial production.Algae, such as the main raw material for the red algae eucheuma and harpoons algae and algae, etc.According to its galactose residues in sulfuric acid ester groups, divided into kappa - type, ι - type, lambda predominate - type.Carrageenan (also called pelvetia silquosa glue or antlers algin) from red algae polysaccharide of natural plant gum, widely used in food industry, chemical industry, and in the field of biological and medical research .
Description: white to light yellow granular or powder, odourless or slight odor;On the palate stick-slip;Soluble in water is about 80 degrees, forming sticky, transparent or light milky liquid solution.
Carrageenan is hydrophilic colloid formation, gel, thickening, emulsification, film, stable dispersion characteristics.Safe and non-toxic characteristics has been the United Nations food and agriculture organization (fao) and the world health organization jecfa (UECFA) identified.
The chemical characteristics
1 Solubility: insoluble in cold water, but can be swelling gel block, insoluble in organic solvents, soluble in hot water into a translucent colloidal solution, begin to dissolve in 70 degrees, 80 degrees is completely dissolved.
2. The gelation sex: in the presence of potassium ions can generate heat reversible gel;
3. The thickening property: low concentration form the low viscosity of sol, close to the Newtonian fluid, form high viscosity of sol concentration increased, the non Newtonian fluid.
4. Collaborative: with locust bean gum, konjac gum, xanthan gum, colloidal generate synergy, can improve the elasticity of gel and water retention;
5. Health value: carrageenan has the basic characteristic of soluble dietary fiber, in the body after degradation of carrageenan complex can form soluble fibrin and blood.Can be colon glycolysis bacteria into CO2, H2, biogas and formic acid, acetic acid, propionic acid, such as short chain fatty acids, become a probiotic sources of energy.
6. Stability: dry powder of carrageenan is stable, long-term place not quickly hydrolysis, than the stability of pectin or algin, sugar.Carrageenan is also stable in neutral and alkaline solution, even heating is not hydrolyzed.
USES: thickening agent;Stabilizing agent;Emulsifier;Suspension +;Gelling agent.Binder.Is widely used in dairy products, ice cream, juice drinks, bread, water gel jelly (water), meat, spices, canned food, etc.Can allocate jelly powder, jelly powder, pudding powder, love jade powder, western-style ham mixing powder, etc.
Cap: all kinds of food, are all GMP is limited.
