Description and Uses
Agar is a gum obtained from red seaweeds of the genera gelidium, gracilaria, and eucheuma, class rhodophyceae. it is a mixture of the polysaccharides agarose and agaropectin. it is insoluble in cold water, slowly soluble in hot water, and soluble in boiling water, forming a gel upon cooling. the gels are characterized as being tough and brittle, setting at 32–40°c, and melting at 95°c. a rigid, tough gel can be formed at 0.5%. agar mainly functions in gel for- mation because of its range between melting and setting tempera- tures, being used in piping gels, glazes, icings, dental impression material, and microbiological plating. typical use levels are 0.1–2.0%.
