But the master beekeeper, who has been keeping hives for more than 40 years, has found herself in a fight against a tricky and evolving foe — honey fraudsters.

The practice of adulterating honey is well known, and historically adulterants such as ash and potato flour have been used.

Now, advancements in technology and science have made it much easier, with “bespoke, designer or bioengineered” syrups used as diluting agents capable of fooling authenticity tests, Ingram said.

She founded the UK Honey Authenticity Network (HAN UK) in 2021 to raise awareness about natural honey and warn of the threat posed by fraud.

“One of the impacts we’re seeing all over the world is beekeepers going out of business,” she said.

Adulterated honey can be sold to retailers for a price several times lower than genuine producers can afford.

As well as producing their own honey, many larger-scale beekeepers have crop pollination contracts with farmers, delivering thousands of colonies to growers across the country.

If they go out of business due to unfair competition, this vital natural method of pollinating crops is reduced and food production suffers.

The British Beekeepers Association, which represents more than 25,000 producers and where Ingram is a honey ambassador, wants the risk of fraud to be recognised to protect the industry and consumers.

“I’d like to see an acknowledgement that there is actually an issue here,” she said.

Better labelling

In May, the European Union updated its honey regulations to ensure clearer product labelling and a “honey traceability system” to increase transparency.

On the labelling for blended honeys, for example, all countries of origin are now required to appear near a product’s name, where previously it was only mandatory to state whether blending had occurred.

Labelling in the UK, which has now left the EU, is not as stringent and Ingram believes consumers are “being misled” by vague packaging.

Behind the EU action is an apparent increase in adulterated honey arriving in the 27-nation bloc.

The substandard adulterates can have adverse effects on consumers’ health, such as raising the risk of diabetes, obesity, and liver or kidney damage.

Between 2021 and 2022, 46 percent of the honey tested as it entered the EU was flagged as potentially fraudulent, up from 14 percent in the 2015-17 period.

Of the suspicious consignments, 74 percent were of Chinese origin.

Honey imported from the UK had a 100-percent suspicion rate.

The EU said this honey was probably produced in third countries and blended again in the UK before being sent to the bloc.

The UK is the second largest importer of honey in terms of volume in the whole of Europe. China is its top supplier.

Not all of the UK’s imported honey leaves the country, however. Considerable quantities stay on the domestic market.

“We think there’s an awful lot of it on the shelves,” said Ingram, adding that adulterated honey was “widely available” in big supermarkets.

Lasers

Behind the closed blinds of a research laboratory at Aston University in Birmingham, central England, researchers fighting honey fraud are harnessing cutting-edge technology.

Aston scientists and beekeepers, including Ingram, are using light to reveal the contents of honey samples at the molecular level.

The technique — known as Fluorescence Excitation-Emission Spectroscopy (FLE) — involves firing lasers into samples.

The light frequencies re-emitted are then collated into a three-dimensional image — or “molecular fingerprint” — of the honey tested.

Alex Rozhin, the project lead and a reader in nanotechnology, said the test “can trace different molecules through the spectrum and confirm which type of biochemicals are present”.

In the darkened lab, the light from different honeys is clearly visible.

The first gives off a vivid green and the second a cooler blue, indicating distinct chemical compositions.

Using FLE, Rozhin says his team “can immediately trace a concentration of fraud inside samples” with “different spectral bands corresponding to syrup (or) to natural honey”.

Rozhin said FLE is more accurate than existing tests and can provide results far quicker, at a greatly reduced cost and without the need for highly trained personnel.

One of the Aston team’s aims is to create a version of FLE that can be used by honey producers or even consumers with scaled-down equipment or eventually just a smartphone.

Rolling the test out like this would also accelerate the creation of a honey database which, through machine learning, could be used as a catalogue of biometric signatures.

“If we get a new sample and it’s been tampered with and it’s different from how the database is built up, we’ll know there’s something obscure,” said Steven Daniels, an Aston research associate specialising in machine learning.

Ingram said the test could close international gaps in testing methods by establishing a unified standard, but the government needed to monitor the sector too.

“We really need to get to grips with this,” she said.
