A quantitative information measure applied to texture perception attributes during mastication

We have calculated an entropy or information measure of previously reported experimentally determined temporal dominance of sensations (TDS) data of texture attributes for two sets of emulsion filled gels throughout the mastication cycle. The samples were emulsion filled gels and two-layered emulsion filled gels. We find that the entropy measure follows an average curve, which is different for each set. The specifics of the entropy curve may serve as a fingerprint for the perception of a specific food sample. An information measure was calculated of experimentally determined temporal dominance of sensations (TDS) frequencies of texture attributes, throughout the mastication cycle. The information measure follows an average curve, different for different food categories. The specifics of the curve may serve as a fingerprint for the perception of such category.image
