In order to distinguish the different consumable truffle species and to confirm their geographical origin, the metabolic profile of the fungi from the genus Tuber could store the answer within. To accomplish this task the polar extract of the fruiting body from authentic samples were analyzed by 1H NMR spectroscopy under water suppression.[1] The spectra of the different truffles covering samples from eight species (Tuber aestivum, Tuber albidum pico, Tuber himalayense, Tuber indicum, Tuber magnatum, Tuber melanosporum, Tuber sinense, and Tuber uncinatum), from nine countries (Australia, Bulgaria, China, Croatia, France, Hungary, Italy, Romania, and Spain) and the harvest years 2017 – 2019 were compared and evaluated by multivariate statistics. For the data analysis principle component analysis and other machine learning algorithms were applied.
