The JuiceScreener™ delivers quality control screening applications for fruit juice including:
 

  • Origin authenticity
  • Species purity
  • False labeling
  • Quantification of relevant organic ingredients
  • Production process control
     

The NMR fruit juice screening method called SGF-Profiling (Spin-Generated Fingerprint) includes an extensive spectroscopic database which contains NMR spectra from mainly authentic samples obtained from production sites all over the world using the AVANCE™ III NMR integrated with a high throughput sampling system and automated data evaluation.

The sensitivity and specificity offered by NMR mixture analysis technology makes this a viable and highly robust screening technique for fruit juice quality control. The method is mainly used as pre-screening to allow targeted conventional analysis which is expensive due to the multitude of tests needed (enzymatic analysis, HPLC, titration).
