Capilano was sent a copy of the results of the tests.
It vigorously denied that any of its products were not pure honey and rejected NMR testing as the best way to determine adulteration.
It said Australian and international regulators “do not use this testing regime at all.”
Capilano said it was 100 per cent confident its Allowrie honey, which is made using up to 70 per cent imported honey, was pure and that it was not surprised by the results given the “weaknesses” in NMR testing as an analytical method.
“We are incredibly concerned that they are being used in isolation of more robust analytical testing, given this is also the opinion of the manufacturer [Bruker] and the two most reputable laboratories in the world [Intertek and QSI], one of which has conducted the NMR analysis,” Capilano said in a statement.
“Our concern lies in the use of these results to create doubt and confusion over the authenticity of honey and how that could be used to mislead the public and consumers.”
Capilano said one of those weaknesses was that the NMR test did not detect that blended honey from different regions was 100 per cent honey, something the German lab, QSI, vigorously denies.
Capilano declined an interview but said it “stands by the quality and purity of all of our honey brands, including Allowrie which has never failed more stringent and appropriate testing by world renowned laboratories.”
Capilano says that two samples from the same batch came back with different results from the two labs using NMR.
QSI’s managing director Gudrun Beckh, who has been testing honey for almost 30 years, said she was confident in the NMR test findings and said if a sample showed up as adulterated it meant the honey was not pure honey.
“Fake honey always existed, but in the last years it’
s a growing problem because of the people who adulterate using more and more sophisticated methods, so it’s more complicated to detect it,” she told 7.30.
QSI performs a variety of tests for clients but Ms Beckh said NMR was the best for detecting adulteration.
She said QSI had an extensive database and used various tests for testing honey but NMR was the most reliable.
She said blended honey from different regions was tested regularly and NMR screening could pinpoint country of origin and botanical origin of the honey.
In the tested samples, she said it was the Chinese aspect of the honey that was adulterated not the Australian honey.
Despite Capilano’s criticisms there is a groundswell of international experts, academics and private companies increasingly relying on NMR as the test of choice for detecting fake honey.
Apimondia, the peak body for the sector internationally, recently said it would use NMR screening as part of its new honey competition rules.
Leaked emails from the local peak industry group, the Australian Bee Industry Council (AHBIC), of which Capilano is a financial member and has board representation, show it wrote to the Department of Agriculture and Water Resources in July requesting it review the way it tests honey, ditching the old C4 test and moving to NMR.
The executive director of AHBIC Trevor Weatherhead said in the email to the department that “AHBIC would ask the department to change to the NMR test if it has not done so already.”
He said it was reported that suppliers that were adulterating honey were finding ways around the C4 sugar test.
“The NMR test has been found to be very effective,” Mr Weatherhead said in an email.
‘It’s time to speak up, before it’s too late’
Fairfax and 7.30 also contacted IGA, ALDI, Coles and Woolworths about the results of the tests.
At 2pm on Friday ALDI temporarily withdrew the two products in its Mixed Blossom Honey range that QSI identified as “adulterated”.
ALDI said it would investigate the claims and if the investigations conclude that the product has been adulterated, it would permanently be removed from sale at ALDI and further actions would be taken with the supplier.
Woolworths said it treated the accuracy of product labelling very seriously.
“We will now work closely with our supplier to review the substance of the claims in detail before determining our next steps,” it said.
Coles said it had deleted all Allowrie products from its shelves for unrelated reasons in July after a range review.
IGA said it meets all the requirements of the Australian and New Zealand food code.
Mallesons was expected to send a copy of the test results to the Australian Competition and Consumer Commission (ACCC) on Monday.
Mr Costa, who bankrolled the honey sample tests, said his concern as a horticulturist was that cheap imported honey was hurting the local industry, which, in turn, would hurt the production of agriculture.
He estimated that 65 per cent of agriculture depended on pollination by honey bees.
“We know what’s going on, we expected it, we just needed the evidence,” he told 7.30.
“I certainly wasn’t shocked.”
Beechworth Honey, Australia’s second-largest honey operator and a major competitor to Capilano, said it only used Australian honey.
Beechworth managing director Jodie Goldsworthy said she supported NMR testing as the best way to detect adulteration.
Ms Goldsworthy said beekeepers of the world had largely been silent about the problem of adulterated honey for fear of hurting the reputation of the industry.
“The silence has made it really easy for the frauds to go on unhindered,” she said.
