Forest mushrooms, due to their taste and smell, have been a component of people's diets since the beginning of time. Unfortunately, there are many inedible or poisonous species of mushrooms that are similar to those that are eaten. For example, the highly valued Boletus edulis is similar to the inedible bitter bolete and the poisonous bolete. In the case of mushrooms of the genus , such similarities are demonstrated by the delicious tasting , the inedible downy and the poisonous cottony . This study presents an attempt to classify these three species based on studies of the emission of volatile organic compounds from the volatile headspace using proton-transfer reaction mass spectrometry (PTR-MS). The conducted statistical tests, principal component analysis (PCA) and discriminant analysis revealed significant differences in the concentration of 20 selected protonated VOC molecules for the tested mushroom species. The clear advantages of the PTR-MS technique are that there is no need for special sample preparation and it has rapid measurement capability and high analytical sensitivity. This allows for a quick comparative analysis of VOCs, for example, from different species of forest mushrooms.
从远古时代起，森林蘑菇因其味道和气味就一直是人们饮食的一部分。不幸的是，有许多不可食用或有毒的蘑菇种类与可食用的蘑菇相似。例如，备受珍视的美味牛肝菌与不可食用的苦牛肝菌和有毒牛肝菌相似。对于[某]属的蘑菇，美味的[某种蘑菇]、不可食用的绒毛[某种蘑菇]和有毒的棉絮状[某种蘑菇]就表现出了这种相似性。本研究尝试通过使用质子转移反应质谱法（PTR-MS）对挥发性顶空的挥发性有机化合物排放进行研究，来对这三个物种进行分类。所进行的统计测试、主成分分析（PCA）和判别分析表明，在所测试的蘑菇物种中，20种选定的质子化挥发性有机化合物分子的浓度存在显著差异。PTR-MS技术的明显优势在于无需特殊的样品制备，具有快速测量能力和高分析灵敏度。这使得能够快速对挥发性有机化合物进行比较分析，例如来自不同种类森林蘑菇的挥发性有机化合物。
