Illegal honey laundering may become a lot more difficult because French scientists from the Université de Lyon have developed and tested a simple method that can distinguish pure, natural honeys from adulterated or impure versions that they say are increasingly showing up on store shelves.
The study by Bernard Herbreteau and his colleagues in Lyon, France was released this week in the Journal of Agricultural and Food Chemistry.
“The high price, limited supply and complexity of honey combine to encourage falsification,” the scientists wrote. “Indeed, despite the technological advent of modern analytical instruments, there is still a problem with the adulteration of high-carbohydrate foods, such as honey, with inexpensive syrups.”
In the U.S., there are four major civilian labs and one government facility that claim the ability to identify adulterated honey.
Yet, when it comes to proving where the honey actually came from, criminal investigators, some U.S. regulators and a only a few of the largest domestic honey sellers send samples to a German lab. The lab says it’s the only place that can identify the precise country of origin of a honey.
Mostly, this analysis is needed to identify falsely labeled Chinese honey, which is smuggled into the U.S. after first being sent to other countries. The Chinese honey often contains illegal antibiotics, according to government authorities.
Criminal investigators from the FDA and Customs and Border Protection (that I interviewed last year) told me they were waiting for verification of the French test.
They hoped it would be faster, less expensive and more consistent and reliable than the laboratory analysis now available in the U.S.
Herbreteau and colleagues say their highly sensitive test uses a special type of chromatography to separate and identify complex sugars on their characteristic chemical fingerprints.
The most common syrups used to adulterate honey are corn syrups and high fructose corn syrup.
“Honey adulteration has evolved from the basic addition of sugar and water to specially produced syrups from which the chemical composition approximately reproduces the sugar composition and ratios of natural honey,” scientists wrote.
