Chewing ability measurement method, chewing ability confirmation system, and dedicated mount

A method capable of objectively, accurately, and simply measuring the color of chewing check gum that has been chewed is desired. Chewing check gum that has been chewed is placed on a dedicated mount 10 on which hue reference colors 12 are displayed, and a camera is used to photograph the dedicated mount 10. A correction amount pertaining to the color of the photographed hue reference color image is calculated by comparing the hue reference colors 12 in the photographed image with the hue reference colors 12 displayed on the dedicated mount 10. The true color of the chewing check gum placed on the dedicated mount 10 is detected by applying the correction amount to the color of the chewing check gum image. The chewing ability of the person who chewed the chewing check gum is measured by applying the true color of the chewing check gum that has been chewed to a chewing ability-determining color scale that has been stored in advance.
