NMR Honey ProfilingTM Update Version 3.0

In recent years, reliable and sensitive NMR analysis of honey has gained tremendous importance worldwide and has firmly established itself as a powerful tool in quality control and for authenticity testing of honey.

In addition to the sensitive detection of foreign sugars (targeted/non-targeted), NMR analysis can be efficiently used to confirm the variety and geographical origin of honey due to the many botanical and geographical database models in combination with microscopy (melissopalynology). Because of the extensive database, NMR is the only analysis that can universally detect a “dilution effect” with foreign sugars (non-targeted).

As of July 12, 2021, we now expect the 3rd release of the Bruker NMR database, which QSI, as a member of the Bruker consortium, has been heavily involved in creating for many years, with thousands of contributed datasets of authentic honeys, and especially our in-depth honey expertise.

In summary, the update to version 3.0 includes the following enhancements:

• More than 28,000 references of authentic honeys
(as well as sugar syrups for differentiation)

(Note: extensive analytical data sets are available for each honey, including pollen analyses incl. sensory analysis, sugar spectra, EA-IRMS/LC-IRMS (C3/C4), oligosaccharides, foreign enzymes , new: HRMS)

• Many new NMR syrup markers (targeted) and improved algorithms for even more sensitive detection of foreign sugars, especially with respect to mannose and DHA, as well as a stricter limit for turanose

• Lower rate of false-positive results due to database clean-up

• New database models and significant increase in the database of existing models:

Botanical origin: Acacia, Chestnut, Eucalyptus, Ling Heather, Lavender, Linden,
Manuka, Orange (Citrus), Pine, Rape, Sunflower, Thyme, Vitex

Geographical origin: Argentina, Brazil, Bulgaria, Canada, Chile, China, Cuba, France, Germany, Guatemala, Hungary, India, Mexico, New Zealand, Romania, Spain, Thailand, Turkey, Ukraine,
Uruguay, Vietnam

We expect that the update to version 3.0 will reduce the differences in evaluation between different laboratories using the Bruker NMR database.

For a comprehensive screening of the authenticity and quality of honey, we always recommend, in addition to NMR as a basis, a pollen analysis (including sensory), a sugar spectrum, and a commercial analysis (water, diastase, HMF, free acid) to obtain the most complete picture possible.

Depending on the origin of the honey, this basic scope can be supplemented with further screening analyses, such as 13C-LC-IRMS and oligosaccharides HPLC-ECD, as well as optionally with further specific methods, such as LC-HRMS, foreign enzymes, psicose or caramel color E150d.

If you have any questions regarding the scope of analysis, we will be glad to advise you. We are also pleased to put together an individual package according to your quality control strategy.
