Abstract

A colorimetric method is described for the quantitative determination of microgramme quantities of vanillin based on its reaction with excess of thiobarbituric acid in aqueous medium containing specified amounts of hydrochloric acid or phosphoric acid. The coloured complex shows a single absorption maximum at 432-434 mμ and the colour intensity of the complex obeys Beer's law at this wavelength when prescribed amounts of vanillin are reacted with thiobarbituric acid. The interference of sugars in the reaction and the application of the method to processed foodstuffs containing vanillin have been discussed.
