Researchers at the Bavarian Health and Food Safety Authority in Oberschleissheim, Germany have found a way to use nuclear magnetic resonance spectroscopy to answer the question "Is it really organic?"The technique has previously been used to authenticate foods like honey and olive oil. The scientists analyzed tomatoes grown in greenhouses and outdoors, with conventional or organic fertilizers and their data showed a trend toward differentiation of organic and conventional produce.
The test is a good starting point for the authentication of organically produced tomatoes, they conclude, and its further refinement could help root out fraudulently labelled foods.
The global market for organic foods nearly tripled in value between 2002 and 2011, reaching $62.8 billion. But because organic food can fetch prices often twice as high as conventionally produced food, the risk for fraudulent labelling has grown just as fast.
