摘　　要： 将5-羟甲基糠醛(HMF)分别与丝氨酸、苏氨酸、γ-氨基丁酸、丙氨酸反应,采用GC-MS共检测出21种挥发性成分,主要为羰基化合物、酮类、呋喃类和烃类化合物。在HMF-丝氨酸反应体系中,吡嗪、5-甲基-2-呋喃甲醛和壬醛在高底物浓度和长反应时间下生成量最高;而在HMF-苏氨酸反应体系中,苯乙酮、3-甲基-吡嗪与2,5-二甲基-吡嗪的生成量随反应时间延长而显著增加,反应物浓度对其没有显著影响;在HMF-氨基丁酸体系中,癸醛的生成量随着反应时间的延长而增多,反应物浓度要在长时间反应条件下才会有显著性差异;在HMF-丙氨酸反应体系中,壬醛和癸醛的生成量随反应时间延长而增多,但在相同反应时间下,却随浓度增加而减少。 The reaction of 5-hydroxymethylfurfural（HMF） with serine,threonine,gamma-aminobutyric acid and alanine,and the relative volatile substances were determined by Gas Chromatography-Mass Spectrometer（GC-MS）. The results showed that 21 volatile components in total were detected from the reaction system of HMF and these amino acids,most of which were carbonyl compounds,furans and hydrocarbon compounds. In HMF-Serine system,the concentrations of pyrazine,5-methyl-2-furaldehyde and nonanal were the highest in the reaction system with the highest contents of the reactants and the longest reaction time. In HMF-Threonine system,the production of acetophenone,3-methyl-pyrazine and 2,5-dimethyl-pyrazine was positively influenced by the reaction time. However,the reactants concentration had no significant effect on their production. In the HMF-aminobutyric acid system,the production of decanal increased as the reaction time prolonged,and the reactant concentration has significant effect under long-time reaction condition. In HMF-Alanine system,the production of nonanal and decanal increased as the reaction time prolonged,while decreased as the initial reactant concentration increased.
