Food physical property assessment method

A food physical property evaluation method comprising:

• placing a food to be evaluated on a lower occlusal part of a lower plunger which has a shape to occlude with an upper occlusal part of an upper plunger and faces the upper occlusal part of the upper plunger;
• causing at least one of the upper plunger or the lower plunger to perform a reciprocating linear movement in a linear direction in which the upper plunger and the lower plunger are occluded and separated, causing at least one of the upper plunger or the lower plunger to perform a reciprocating rotation movement in a rotation direction with the linear direction as a rotation axis, and adjusting a pressure applied between the upper plunger and the lower plunger by a power of a motor or an elastic force of a solid elastic body;
• and
• measuring a physical quantity including:
• (i) a force applied to the upper plunger or the lower plunger;
• and (ii) a torque applied to the upper plunger or the lower plunger, and evaluating food physical properties based on the physical quantity.
