61 different non-volatile compounds were determined in Agaricus Bisporus sliced mushrooms using UHPLC/Q-TOF with MS(E) technology. Both positive and negative electrospray ionization were applied. Chemical profile of three parts of mushroom was created: cap, gills and stipe. The analysed mushrooms were oxidized to identify the non-volatile markers in their parts. MarkerLynx(®) was proposed as a powerful tool to distinguish mushrooms purchased in different countries (Spain and Portugal) by determining their non-volatile markers. Some metabolites were identified. Surprisingly a mix of polyethylene glycols (PEGs) was detected in cap and gills of mushrooms. Whole mushrooms were considered as vegetable resistant to migration from packaging compounds. Additionally migration tests were performed to determine the source of migrating compounds.
采用超高效液相色谱/四极杆飞行时间质谱联用（UHPLC/Q-TOF）的MS(E)技术测定了双孢蘑菇切片中的61种不同非挥发性化合物。同时应用了正、负电喷雾电离。创建了蘑菇三个部分（菌盖、菌褶和菌柄）的化学图谱。对分析的蘑菇进行氧化处理以鉴定其各部分中的非挥发性标志物。MarkerLynx(®)被认为是一种强大的工具，通过测定非挥发性标志物来区分在不同国家（西班牙和葡萄牙）购买的蘑菇。鉴定出了一些代谢物。令人惊讶的是，在蘑菇的菌盖和菌褶中检测到了聚乙二醇（PEGs）的混合物。整个蘑菇被认为是对包装化合物迁移具有抗性的蔬菜。此外，还进行了迁移测试以确定迁移化合物的来源。
