Abstract

A novel apparatus can be used to simulate the chewing process, wherein the wherein the apparatus comprises a thermostattable kneading space comprising an upper portion and lower portion, wherein the lower portion comprises at least two kneading paddles for comminuting and kneading the test material and the upper portion comprising an air space for connecting the volatile components released during the comminution and kneading, wherein said apparatus comprises an inlet in which saliva is introduced into the kneading space and a second inlet in which air is passed into the kneading space, wherein air is passed together with the volatile components of the comminution and kneading process through an outlet of the kneading space to a detector system.

Claims

1. An apparatus for simulating the chewing process, wherein the apparatus comprises a thermostattable kneading space comprising an upper portion and lower portion, wherein the lower portion comprises at least two kneading paddles for comminuting and kneading the test material and the upper portion comprising an air space for connecting the volatile components released during the comminution and kneading, wherein said apparatus comprises an inlet in which saliva is introduced into the kneading space and a second inlet in which air is passed into the kneading space, wherein air is passed together with the volatile components of the comminution and kneading process through an outlet of the kneading space to a detector system.

2. An apparatus according to

claim 1

, wherein the kneading space is thermostatted to a physiological temperature.

3. An apparatus according to claims 1 and 2, wherein the kneading paddles are covering most of the volume of the lower portion of kneading space.
