Improved Method for Detecting Honey Adulteration

Improved Detection of Honey Adulteration by Measuring Differences Between 13C/12C Stable Carbon Isotope Ratios of Protein and Sugar Compounds with a Combination Of Elemental Analyzer - Isotope Ratio Mass Spectrometry and Liquid Chromatography - Isotope Ratio Mass Spectrometry

Abstract – The detection of honey adulteration with invert sugar syrups from various C3 and C4 plant sources was realized by coupling an isotope ratio mass spectrometer both to an elemental analyzer and to a liquid chromatograph (EA/LC-IRMS)…

The newly developed EA/LC-IRMS method and the purity criteria defined represent a significant improvement compared to existing methods.
