A simple ~1H NMR method for the quantification of carrangeenans in blends

摘要

Tranditional methods for the structural analysis of carrageenans require hydrolysis and derivation procedures followed by chromatographic analysis of the formed derivatives.These assays are time-consuming and do not adequately quantify the different components in blend samples. This paper describes a simple method for the quantitative determination of kappa,iota and lambda carrageenan in standard mixtures of samples and production batches on intact polymeric carrageenans using ~1H NMR spectroscopy.
