Madison, WI, United States, 2014/03/03 - NMR (Nuclear Magnetic Resonance) screening of juices, pulps and purees now significantly enhanced through increased quantification parameters and wider coverage, providing reliable targeted and non-targeted multi-marker analysis - Bruker.com. NASDAQ: BRKR
Bruker today announced the third release of its successful NMR JuiceScreenerTM. The new release comes with significant enhancements that enable the accurate, swift, automated screening of even more fruit juice types from just a single experiment. From an expanded Database of spectra now containing more than 16,000 samples obtained from production sites all over the world, with over 300,000 NMR references values, determination of origin and detection of adulteration now covers 19 types of fruit and 10 types of juice.
The JuiceScreener 3.0 uses the SGF Profiling™ NMR-based screening method that was jointly developed by Bruker BioSpin GmbH and SGF International e.V. Now new statistical models combined with further enhanced principal models provide increased reliability. Reference distribution of compound concentrations is now based on an enhanced list of more than 300,000 NMR values, whilst for validation, more than 12,000 conventional values are available.
The JuiceScreener 3.0 now offers coverage of high-value products such as passion fruit juice, pomegranate juice and mango puree. Classification analysis includes the determination of fruit origin. Coverage now includes origin determination of Mango Puree (available origins are Mexico and India), and detection of addition of Peach and Apricot in the respective other type of puree.
Current major fraud worldwide relies on incorrect fruit content and the addition of water, amino acids and sugar. Now these parameters can be quickly determined for more than 10 types of juice (including pomegranate, passion fruit, and grapefruit). The enhanced quantification list of fruit types covered includes new compounds coverage, e.g. 4-aminobutanoic acid, arginine and xylose.
“Quote… perhaps regarding Targeted and Non-targeted Analysis?” said Dr. Manfred Spraul, Bruker’s Director of Applied NMR Development.
