Notwithstanding the differences of the aromatic profile presented above, the two samples also shared some common features. According to Table 1, some volatile compositions (34 in total) were found in both of the truffle samples, which accounted for 47.9% of the total aroma compounds. The identical compounds included 7 alcohols and phenols, 10 aldehydes, 1 hydrocarbon, 2 ketones, 8 acids, 2 esters, 3 furans and furanones and 1 sulfur-containing compound.
