This study investigated the effect of the odors generated by the glycine/glucose Maillard reaction and the potent odorants 2,3-dimethylpyrazine (3DP) and 2,5-dimethyl-4-hydroxy-3(2)-furanone (DMHF) on the human mood and integrative physiological activity. The score of certain subjective moods, especially anger-hostility, and tension-anxiety were decreased significantly after inhalation of the Maillard reaction sample and DMHF, and fatigue-inertia mood was also significantly decreased by DMHF, suggesting a sedative effect of these odors on mood, while 3DP had no effect. Miosis rate and fingertip temperature increased significantly following inhalation of the odor from the Maillard reaction sample and both potent odorants, suggesting that the parasympathetic nervous system dominates through suppression of the sympathetic activity. The physiological relaxing effect of these odors was also confirmed by decreased flicker frequency value and decreased oxyhemoglobin in the prefrontal cortex.
本研究调查了甘氨酸/葡萄糖美拉德反应产生的气味以及强效气味剂2,3 - 二甲基吡嗪（3DP）和2,5 - 二甲基 - 4 - 羟基 - 3（2）- 呋喃酮（DMHF）对人类情绪和综合生理活动的影响。吸入美拉德反应样品和DMHF后，某些主观情绪的得分，尤其是愤怒 - 敌意和紧张 - 焦虑得分显著降低，DMHF还使疲劳 - 惰性情绪显著降低，表明这些气味对情绪有镇静作用，而3DP则无此作用。吸入美拉德反应样品的气味以及两种强效气味剂后，瞳孔缩小率和指尖温度显著升高，表明副交感神经系统通过抑制交感神经活动起主导作用。前额叶皮层中闪烁频率值降低和氧合血红蛋白减少也证实了这些气味的生理放松作用。
