Sodium alginate

About Sodium alginate

Name  Sodium alginate
Synonyms  Alginic acid monosodium salt
CAS Registry Number  9005-38-3
Sodium alginate is a good chelator for pulling radioactive toxins such as iodine-131 and strontium-90 from the body which have taken the place of their non-radioactive counterparts.[1][2] It is also used in immobilizing enzymes by inclusion.
A major application for sodium alginate is as thickener for reactive dyestuffs (such as the Procion cotton-reactive dyes) in textile screen-printing and carpet jet-printing. Alginates do not react with these dyes and wash out easily, unlike starch-based thickeners.
As a food additive, sodium alginate is used especially in the production of gel-like foods. For example, bakers' "Chellies" are often gelled alginate "jam." Also, the pimento stuffing in prepared cocktail olives is usually injected as a slurry at the same time that the stone is ejected; the slurry is subsequently set by immersing the olive in a solution of a calcium salt which causes rapid gelation by electrostatic cross-linking. A similar process can be used to make "chunks" of everything from cat food through "reformed" ham or fish to "fruit" pieces for pies. It has the E-number 401. Now-a-days it is also used in the biological experiments for the immobilization of cells to obtain important products like alcohols, organic acids,etc.
