Abstract

The sulphur contents of samples of three types of carrageenan and protein/carrageenan complexes have been determined using simultaneous Deuteron Induced X-ray Emission (DIXE) and Nuclear Reaction Analysis (NRA). The measured relative sulphur contents of the carrageenan samples were in close agreement with those expected from their chemical structures. Analysis of carrageenan precipitated protein/carrageenan complexes, samples not amenable to conventional chemical assays, indicates that precipitation is less efficient at carrageenan levels above 50ppm. At such levels the excess carrageenan remains in solution and represents a waste of a costly resource in a commercial environment.
