Open publisher page 4 citations

Abstract

A spectrophotometric determination of vanillin based on the reaction between vanillin and thiobarbituric acid in hydrochloric acid solution is described.The absorbance is measured at 438nm.The linear range of the calibration curve is 1×10 -6 ～1 5×10 -4 mol/L.The detection limit of vanillin is 4.47×10 -8 mol/L.This method for determination of vanillin was proved to be simple,rapid and accurate.It is used for the determination of vanillin in some foods successfully.
