| Food grade sodium alginate |
 Sodium alginate (C5H7O4COONa)n,also called algin, is one kind of electrolyte of organic macromolecule among algae of brown algae types, such as kelp, as principal components of cell membrane with other substances. Food grade sodium alginate is in the form of ivory-white granule or powder, odourless, low odor of sourness.
Chemical components of sodium alginate belong to carbohydrate and it only contains free carboxyl (-COONa) in contrast with starch and fibrin. At the same time, it is one kind of chain type macromolecule heteropolymer brought by copolymerization between mannuronic acid and guluronicacid.
Degree of polymerization of sodium alginate differs according to raw materials and distilling methods. Generally speaking, degree of polymerization of common algin is within the range from 80 to 750, molecular weight is from 14000 to 132000. Equivalent weight of sodium alginate is 196.
