在以前的工作中，鼻后嗅觉是感知硫酸亚铁（FeSO4）金属感觉的重要线索。本研究的目的是检查是否FeSO4产生口腔感觉以及鼻后线索和是否涩味有助于口腔感觉。在第一项研究中，歧视的FeSO4从水被证实在浓度等于或高于5毫米没有鼻后流。第二项研究检查了FeSO4和CuSO4是否可以通过触觉在非味觉区检测到。当硫酸铜溶液被施加到牙龈和上唇之间的非味觉表面时，无论是否有鼻后线索，都能感知到涩味。但FeSO4的涩味低于CuSO4，与水的涩味差异不显著。来自铁盐的其他味觉或触觉可能有助于它们的口腔感觉，并且金属感觉的至少一部分可能是金属味道的可能性仍然存在。
In previous work, retronasal smell was an important cue for perceiving metallic sensations from ferrous sulfate (FeSO4). The purpose of this study was to examine whether FeSO4produced oral sensations as well as retronasal cues and whether astringency contributed to the oral sensations. In the first study, discrimination of FeSO4from water was confirmed at concentrations at or above 5 mM without retronasal flow. A second study examined whether FeSO4and CuSO4could be detected on a non-gustatory region by tactile sensations. Astringency was perceived when the copper sulfate solution was applied to non-gustatory surfaces between the gum and the upper lip with or without retronasal cues. However, rated astringency for FeSO4was less than that for CuSO4, and not significantly different from water. Other gustatory or tactile sensations from iron salts may contribute to their oral sensations and the possibility remains that at least one part of metallic sensation may be a metallic taste.
