Figure 3: Glu and Na concentration within each institute. The line pattern of each symbol shows the type of dashi, and the shape of each symbol represents the type of miso, as shown under the graph. One symbol represents an average value (2 or 3 miso soups) of each institution. Therefore, each symbol represents the major dashi and miso values of each institution. Concentrations are represented in logarithmic axes, because taste intensity is proportionate to the logarithmic value of the concentration of each tastant.
