Is this really organic? A new test will tell.
A new test could determine if your food is really organic.
Slapping on the “organic” label to inflate the price of produce might become a thing of the past thanks to researchers from the Bavarian Health and Food Safety Authority and the Würzburg University in Germany, who have developed a high-tech test to set the standards.
Despite tightening laws and increasing proactivity from food watchdog groups in some countries, organic food fraud continues to occur because the label can fetch double the price of conventional produce.
Researchers explored a technique called magnetic resonance spectroscopy that is already in use for authenticating honey and olive oil.
Comparing tomatoes that had been grown either in greenhouses or outdoors with conventional or organic fertilisers, they collected enough data to prove their method could identify the aforementioned conditions.
Researchers say the current authentication technique, which analyses the stable isotope composition of nitrogen, is not sufficiently accurate.
The study was published in the American Chemical Society Journal of Agricultural and Food Chemistry. – AFP Relaxnews
