<P>PROBLEM TO BE SOLVED: To automate all the processes for measuring in a device to measure masticatory ability using gummi jelly containing coloring matter. <P>SOLUTION: The masticatory ability measuring device includes a container to contain masticated pieces of gummi jelly, a measuring base 12 on which the container is installed, an agitation head 3 arranged at an upper position of the measuring base 12 to be capable of elevating and rotating around a vertical axis so as to penetrate into the container on the measuring base 12, a head elevation drive mechanism to elevate the agitation head 3 to move, a head rotation drive mechanism to drive the agitation head 3 to rotate around the vertical axis, a water supply and drain water to and from the container on the measuring base 12, and a means to measure the color depth of the coloring matter liquated into water from the masticated pieces housed in the container on the measuring base 12. Using a relational expression preliminarily determined by regression analysis, increased quantity in surface area of the gummi jelly is introduced based on output values of the color depth measuring means to be set for measurement of masticatory ability. <P>COPYRIGHT: (C)2012,JPO&INPIT |
