Bruker Announces Next Generation JuiceScreener™ 3.0
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.
CHICAGO, Illinois – March 3, 2014 – At Pittcon 2014, 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. The expanded database of reference
spectra now contains more than 16,000 samples obtained from production sites all over the world, containing more than
300,000 NMR reference values covering more than 19 different types of fruit, enabling the detection of several adulterations
and the determination of fruit origin, depending on the type of fruit.
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
Determination of the origin of orange juice
using NMR JuiceScreener
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.
“Since its launch the JuiceScreener has had a significant impact on production and has benefited the endconsumer. Taking the example of raspberry juice and puree fraud, from a substantial number of fraud cases identified in
2009, a review in 2013 has shown the same market to be almost completely clean. As the awareness of NMR’s ability to
detect even the most complex fraud approaches has spread, the rate of occurrence is diminishing. With this new release
Bruker has substantially increased the number of fruit types covered, now enabling, for example, clear identification of
dilution in combination with the addition of sugars and other ingredients. The inclusion of premium juice types will now help
tackle fraud in higher priced markets,” said Dr. Manfred Spraul, Bruker’s Director of Applied NMR Development.
