Abstract
A method of selecting a commercially viable chewing gum including testing a chewing gum using nonlinear rheology, compiling rheological data from the nonlinear rheology, and then comparing the rheological data obtained to rheological data ranges of commercially acceptable chewing gum. The nonlinear rheology can include large amplitude oscillatory shear test, start-up of steady uniaxial extension test, and uniaxial compression test (lubricated or unlubricated) and relaxation.

A method of selecting a commercially viable chewing gum comprising:
- a) testing a chewing gum using nonlinear rheology;
- b) compiling rheological data from the nonlinear rheology;
- and
- c) comparing the rheological data from the nonlinear rheology to rheological data ranges of commercially acceptable chewing gum.
A method of selecting a commercially viable chewing gum comprising:
- a) measuring rheological properties of a chewing gum product in a nonlinear viscoelastic region;
- b) comparing such measured nonlinear rheological properties of the gum with nonlinear rheological properties of known commercially acceptable chewing gum product;
- and
- c) determine a commercially viable chewing gum product based on such comparison.
