Influence of taste and flavor on the circulation response during chewing

关于口腔颌面功能的恢复和维持与全身健康状况的关系，国内外已有大量的研究，但均未详细探讨咀嚼过程中产生的“美味”等情绪对脑循环和体循环的影响。在应用研究中，为了探讨味觉和风味对咀嚼过程中循环反应的影响，我们同时测量了咀嚼不同味觉和风味的受试食物时的脑循环、体循环和自主神经活动。在研究期间，我们使用六种不同味道和风味的口香糖进行了实验，我们发现，当受试者咀嚼味道和风味的食物时，大脑和体循环增加最多。当受试者咀嚼有味道的食物时，心交感神经活动也增加最多，但血管神经活动没有明显增加。脑循环的变化与味觉和风味的感官评价结果之间存在相关性，这表明咀嚼过程中的情绪变化可能会影响循环反应。

A number of studies have been made about relationship between the systemic health condition and the restoration or maintenance of stomatognathic functions not only in dental filed but also in others, but none of them investigated in detail how the emotions such as "tasty" caused during chewing influence on the cerebral and systemic circulation. In the research for application, with a view to investigate the influence of taste and flavor on the circulation response during chewing, we simultaneously measured the cerebral circulation, the systemic circulation and Autonomic nervous activity during chewing of subject foods with different taste and flavor. During the research period, we conducted experiments using six types of gum with different taste and flavor, and we found that the cerebral and systemic circulation increased most when subjects chewed foods with both taste and flavor. The Cardiac sympathetic nerve also increased most when the subjects chewed foods with taste and flavor, but the blood vessel nerve activity did not increase significantly. There was a correlation between change in the cerebral circulation and the results of organoleptic evaluation on taste and flavor, and it was suggested that the change in emotion during chewing may affect the circulation response.
