Agar is a natural macromolecule polysaccharide product extracted from seaweeds such as porphyra and Gracilaria etc. and refined by scientific methods. It is composed of Agarose and Agaropectin. Agar is usually white or tiny yellow, free of smell or having light characteristic smell. It can't dissolve in cold water but can easily dissolve in boiling water and dissolve slowly in hot water.
Function:
Agar is derived from the polysaccharide agarose, which forms the supporting structure in the cell walls of certain species of algae, and which is released on boiling. These algae are known as agarophytes and belong to the Rhodophyta(red algae) phylum. Agar is actually the resulting mixture of two components: the linear polysaccharide agarose, and a heterogeneous mixture of smaller molecules called agaropectin.
Application:
In food industry: As gelatinizing and stabilizing agent used in candy,jelly, yokan,canned food, ham and sausage; As thickening and stabilizing used in jam, peanut butter, sesame soy; As stabilizing used in ice cream, popsicle etc; As stage-deflocculant used in fruit juice and beverage; As clarifying agent used in wine, soy sauce, vinegar.
In bio-engineering industry: Bacterium culturing medium and microorganism carrier, etc.
