Carrageenan History
Carrageenan (CAS NO.9000-07-1) or carrageenins are a family of linear sulphated polysaccharides extracted from red seaweeds.The name is derived from a type of seaweed that is abundant along the Irish coastline. Gelatinous extracts of the Chondrus crispus seaweed have been used as food additives for hundreds of years,though analysis of carrageenan safety as an additive continues.
Carrageenan Specification
The Carrageenan, with the CAS registry number 9000-07-1,is also known as Aquagel; Gum carrageenan . It belongs to the product categories of Natural Product ; Pharmaceutic aid [suspending agent]. It is a water-soluble extractive mixture of sulfated polysaccharides from red algae. chief sources are the irish moss chondrus crispus (carrageen), and gigartina stellata. it is used as a stabilizer, for suspending cocoa in chocolate manufacture, and to clarify beverages.
