To provide a chewing evaluation method capable of easily measuring chewing
by an easy method without using a special expensive apparatus, together
with a chewing determination kit, the chewing determination kit comprises
testing food which contains ascorbic acid, an ascorbic acid derivative,
and/or ethanol as detection components, and an indicator reacted with the
components, based on a fact that there appears a difference in a leaching
out state of components for chewing determination depending on a chewing
degree when testing food containing the components for chewing
determination is used as a factor which is necessary for chewing
determination in a wide sense but lacks in the conventional chewing
determination method.
