Agar Agar CAS 9002-18-0

Product name: Agar Agar CAS No.: 9002-18-0 Description Agar is Polysaccharides from various species of Rhodophyceae mainly belonging to the genus Gelidium. It is prepared by treating the algae with boiling water; the extract is filtered whilst hot, concentrated and dried. Agar is commercially available as white to pale yellow bundles consisting of thin, membranous agglutinated strips, or in cut, flaked, granulated, or powdered forms. Agar is a generic name given to a group of related molecules with a repeating unit of agarobiose formed basically by D- and L-galactose units interlinked with α-1,3 and α-1,4 linkages. Approximately every tenth D-galactopyranose unit contains a sulfate ester group. It is insoluble in cold water, but it is soluble in boiling water. Applications Agar is a natural hydrocolloid extracted from various seaweeds. Because of its special gelling properties, especially its remarkable stability and hysteresis, agar has been widely used in food, medicine, chemical industry, textile, national defense and other fields. In the food industry, it has excellent functions as extenders, thickeners, emulsifiers, gelling agents, stabilizers, excipients, suspending agents, and moisture retention agents. It can be used to produce candy, pie, canned meat, juice drink, pulp drink, ice cream, yogurt, dairy cake, etc. Agar has strong gelling ability, and its gel strength increases when it is used with dextrin or sucrose. Agar can also be used as silk sizing agent, laxative agent, adhesive, thickener and capsule of medicine. It can also be used as bacterial culture medium, immobilized enzyme carrier, bacterial coating material and electrophoresis medium. It can also be used for the filtration and separation of viruses, subcellular particles and macromolecules, as well as the observation of serum antigens or antibodies.
