Inexpensive spring truffles or exquisite piedmont truffles? - EurekAlert
<em>Some truffles are particularly expensive and therefore often the target of food fraud. For example, high-priced Piedmont truffles (Tuber magnatum) are often difficult to distinguish from the cheaper spring truffles (T. borchii) on the basis of their appearance. Two scientists from the Leibniz Institute for Food Systems Biology at the Technical University of Munich have now developed a new method of analysis. This allows both truffle species to be distinguished objectively and clearly using just two marker compounds. "The method is also fundamentally suitable for routine analyses," explains principal investigator Martin Steinhaus. </em>
