Research Abstract

We examined the effects of the volatile fractions in niboshi soup stock on the perception of the umami taste using a sensory evaluation and functional magnetic resonance imaging (fMRI). The umami intensity in the volatile fractions was greater than that in the mixture of amino and nucleic acids. The umami perception of volatile fraction might be due to the activation of the olfactory area and the dorsolateral prefrontal cortex in the brain.
