The present invention provides a evaluating system of masticatory
efficiency comprising, a first step of allowing a human subject to
masticate an artificial food material containing microparticles that are
finely crushed and ground by mastication and keep a spherical shape
unless they are masticated; a second step of enlarging the artificial
food material having been thus masticated by applying pressure to a
thickness equal to the diameter of the microparticles while sandwiching
the artificial food material between two preparation sheets; and a third
step of counting microparticles keeping the spherical shape that remain
in the artificial food material having been enlarged between the two
preparation sheets by applying pressure.
By using this evaluating system in the invention, the masticatory
efficiency can be evaluated well in precise and at short time without
using a solvent and expensive instruments.
