At a laboratory in Austria’s mountainous Tyrol province, scientists are DNA testing about 100 honey samples a month to find out about their composition — and in some circumstances to decide whether or not they have been adulterated.

With faux honey flooding markets, and just a few European laboratories working such evaluation, the small Austrian firm Sinsoma started providing the exams two years in the past.

“It is really something new for the honey market,” stated Corinna Wallinger, head of gross sales at Sinsoma.

It is important that know-how “always moves forward — just as the counterfeiters” do, she added.

Honey can not have elements corresponding to water or cheap sugar syrups — which could increase its quantity — added to it, in accordance to EU laws.

But exams have proven that’s frequent follow.

Between 2021 and 2022, 46% of the honey examined below an EU investigation because it entered the bloc was flagged as doubtlessly adulterated, up from 14% within the 2015-17 interval.

Of the suspicious consignments, 74% had been of Chinese origin.

Beekeepers’ livelihoods threatened

Seeking to higher detect fraud, Austria’s well being and meals security company (AGES) used DNA testing for the primary time this yr and remains to be evaluating the outcomes.

European grocery store chain SPAR additionally ordered DNA exams for its honey.

The chain put its honeys — taken off the cabinets late final yr in Austria for testing — again after they handed DNA exams and one other evaluation.

Besides dishonest customers, faux honey threatens the livelihood of beekeepers, who wrestle to compete with the far decrease costs of imported honey — typically blended from numerous international locations — and are demanding more practical testing.

“We don’t have a chance at all,” stated Matthias Kopetzky, proprietor of the Wiener Bezirksimkerei, which takes care of up to 350 hives in Vienna, as bees buzzed round him on a meadow overlooking the capital.

While the European Union is the world’s high honey producer after China, it is usually the second-biggest importer after the United States.

Most of the bloc’s honey imports come from Ukraine, China and Argentina, in accordance to EU information.

An EU directive adopted final yr stipulates that honey labels from mid-2026 should element the international locations of origin, as opposed to merely referencing a “blend of EU and non-EU honeys”.

Beekeepers like Kopetzky hope the brand new rule will increase client consciousness.

Brussels additionally arrange a bunch of specialists, with a mandate till 2028, to “harmonise methods to detect adulteration in honey and trace the product back to the harvesting producer or importer”.

Rigorous course of

Austria’s Sinsoma has specialised in DNA testing.

“Honey is full of DNA traces, of information from the environment where bees collected the nectar. Every honey has a unique DNA profile,” Wallinger stated.

When a honey pattern lacks a variety of DNA traces or for instance comprises a excessive proportion of DNA traces from rice or corn — which bees don’t frequent — this means a honey just isn’t real, she added.

Co-founded by Wallinger in 2018, Sinsoma now employs a couple of dozen folks working within the small laboratory room and adjoining open workplace house within the quiet city of Voels close to Innsbruck.

Sinsoma fees beekeepers 94 euros ($103) for a fundamental DNA take a look at concentrating on vegetation — about half of what a basic pollen take a look at would usually price, she stated.

For the DNA profile, beekeepers additionally get a QR code which permits customers to see precisely which plant species the bees making the honey have frequented, she stated.

Experts warn the DNA technique can detect sure kinds of fraud however not all, and {that a} rigorous strategy of validation is required to guarantee reliable outcomes.

Wallinger recognised the necessity for standardisation of the strategies however stated this may take time.

“It is always somewhat of an issue — and this is also the case at the EU level,” she stated.

“If you always wait until you can use a standardised method to uncover a fake honey, then you will always be lagging behind what counterfeiters are doing.”
