Evaluation of Sorbitol as an Endogenous Isotopic Reference Marker Compound for the Detection of C4-Type Sugar Adulteration in Apple Juice
Language: English | Duration: 25:31 minutes
Can a naturally occurring sugar alcohol help combat food fraud? The presentation from Dr. Philipp Schodder, Elementar Analysensysteme GmbH during the IRMS User Meeting explores how sorbitol can serve as an internal isotopic reference marker for detecting adulteration in apple juice. Learn how LC-IRMS enables the simultaneous analysis of sorbitol and sugars in a single run, providing a streamlined approach to identifying the addition of C4 sugars and other fraudulent practices. The session highlights the advantages of using an endogenous marker, demonstrates the method's sensitivity through real-world validation studies, and discusses its potential for broader applications in fruit authenticity testing.
Join this presentation to discover an innovative isotope-based strategy for strengthening food authenticity testing and improving confidence in fruit juice analysis.

A simpler way to detect exogenous C4 sugar adulteration in apple juice using LC-IRMS
Naturally occurring sorbitol can be measured in the same LC-IRMS run as the major sugars and provides a reliable isotopic reference point for detecting added C4 sugars in apple juice - a common adulteration issue.
By measuring sorbitol alongside the other sugar components, the method removes the need for extensive sample preparation and multiple analytical workflows, making routine analysis much more straightforward. Coupled with the excellent robustness and ease-of-use of the iso CHROM LC interface, the method could be a significant development to help detect food adulteration.
