Figure 1From: The important role of umami taste in oral and overall healthNewly developed umami taste sensitivity test using filter paper disk test. Monosodium glutamate was used as an umami taste solution. Filter paper of 5-mm diameter was soaked with a taste-inducing chemical solution and placed on specific areas of the tongue and oral cavity using tweezers. The subjects were exposed to six different concentrations of umami solution: 1, 5, 10, 50, 100, and 200 mM. The lowest concentration at which the patient could detect and recognize the taste was defined as the recognition threshold.Back to article page
