FOODS:喝咖啡竟会改变我们的味觉!

2020-05-12 MedSci原创 MedSci原创

咖啡(普通咖啡和无咖啡因咖啡)改变了随后的味觉感知,特别是可以增加对甜味的敏感性和降低对苦味的敏感性。

化感敏感性在个体之间有很大的差异。这种差异使化感诊断复杂化,同时也使创造受所有人欢迎的美食更具挑战。

为了保证化感功能的准确定性,常用的经验法则是在化感检测前一小时避免进食/饮水。然而,至今为止,这个时间禁食的科学依据仍不清楚。此外,我们对于咖啡对即时化感的作用还不清楚,其可能会对胃肠道和肝脏功能的优化产生影响。

最近一项研究的目的是调查咖啡消费对即刻味觉和嗅觉敏感性的模块效应。研究人员纳入了155名参与者。通过对咖啡摄入前后的嗅觉和味觉敏感度进行测试,研究人员发现嗅觉敏感度没有变化,但参与者对一些基本的味觉敏感度有显著改变。

研究人员重复使用无咖啡因咖啡进行试验,发现了类似的结果。

因此,该结果表明,咖啡(普通咖啡和无咖啡因咖啡)改变了随后的味觉感知,特别是可以增加对甜味的敏感性和降低对苦味的敏感性。

该研究结果提供了咖啡如何影响短期味觉敏感度的第一个证据,进而影响了我们对食物的感觉和感知方式--这在胃肠学以及化学感官测试程序中是一个重要的启示。
