A modified GC method was utilized for the detection and quantitative determination of sugars derived from commercial gum, Agar, Carageenan, Xanthan, Gum Ghatti, Gum Arabic, Emulgum, Gum Tragacanth, and Gum Karaya. The polysaccharides were cleaved by acid hydrolysis, derivatized with "STOX" hydroxylamine to form oxime with "TM%" or HMDS +TFAA" for silylation. The separation and quantitation was performed by gas chromatography, using phenyl-B-D-glucopyranoside as the internal standard for quantitative analysis. Sugar molar ratios (percent) for all commercial gums tested were similar to literature values.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
