Agar is a polysaccharide complex extracted by bleaching and hot water treatment of agarocytes from the red alga Rhodophyceae, it is composed of approximately 70% agarose and 30% agaropectin. Agarose is a neutral gelling component which is composed of a linear polymer of alternating D-galactose and 3,6-anhydrogalactose units. Agaropectin is a non-gelling component which consists of b-1,3-glycosidically linked D-galactose units.
Application Notes
According to the Merck Index, agar is typically used in microbiology and bacteriology to make solid culture media for microorganisms; as an antistaling agent in bakery products, confectionery, meats and poultry; as a gelling agent is cosmetics, desserts and beverages; as a corrosion inhibitor; in sizing for paper and silks; in adhesives; in the dyeing and printing of textiles and fabrics; and as a protective colloid in ice cream, pet foods, health foods, laxatives, pharmaceuticals, dental impressions, lab reagents and photographic emulsions.
