AN82: Analysis of Fruit Juices Adulterated with Medium Invert Sugar from Beets (Method A) Be the first to rate this application

fruit juice adulteration by carbohydrates

Description

Fruit juice adulteration presents an economic & regulatory problem. Investigators using high performance anion exchange chromatography with pulsed amperometric detection (HPAE-PAD) have discovered several components in beet medium invert sugar (BMIS) that are not present in orange juice. The selectivity of anion-exchange chromatography, for oligosaccharides, and the sensitivity and specificity of pulsed amperometric detection make HPAE-PAD uniquely suited to this analysis. Today we would use a different electrochemical waveform (see TN21) and post-column addition of NaOH would not be required.
