Volatile compounds produced by Pseudomonas perolens ATCC 10757 in sterile fish muscle (Sebastes melanops) were identified by combined gas-liquid chromatography and mass spectrometry. Compounds positively identified included methyl mercaptan, dimethyl disulfide, dimethyl trisulfide, 3-methyl-1-butanol, butanone, and 2-methoxy-3-isopropylpyrazine. Compounds tentatively identified included 1-penten-3-ol and 2-methoxy-3-sec-butylpyrazine. The substituted pyrazine derivative 2-methoxy-3-isopropylpyrazine was primarily responsible for the musty, potato-like odor produced by P. perolens.
采用气液色谱和质谱联用技术，对无菌鱼肉（黑眼岩鱼）中由佩罗氏假单胞菌ATCC 10757产生的挥发性化合物进行了鉴定。已确定的化合物包括甲硫醇、二甲基二硫醚、二甲基三硫醚、3-甲基-1-丁醇、丁酮和2-甲氧基-3-异丙基吡嗪。初步确定的化合物包括1-戊烯-3-醇和2-甲氧基-3-仲丁基吡嗪。取代吡嗪衍生物2-甲氧基-3-异丙基吡嗪是佩罗氏假单胞菌产生霉味、类似土豆气味的主要原因。
