Abstract:
In this study, a simple technique was developed to determine the aldehyde content on an oxidized-polysaccharide. 2,3,5-triphenyltetrazolium chloride (TTC) was used to measure aldehyde analytically by UV-Vis spectrophotometric assay. Comparable results were obtained when tested against the known aldehyde contents of formaldehyde, acetaldehyde, and glutaraldehyde. The TTC UV-Vis assay was further employed to check the aldehyde produced during oxidation of natural polysaccharide konjac glucomannan (KGM). It was found that TTC UV-Vis assay was accurate even at low concentrations of aldehyde and thus this assay could be used to optimize the reaction parameters of oxidation.
