A measure of the reliability (T-IR) of time-intensity measurements was developed based on the concept of standard deviation as a measure of panellist variability. The T-IR measure was applied to time-intensity data collected from 10 panellists evaluating the sweetness of 4 model sweetener solutions on horizontal and vertical time-intensity line orientations.
Dual-attribute time-intensity is a new technique for evaluating the perception of two sensory attributes simultaneously. In this research, the sensitivity of dual-attribute time intensity was assessed in comparison to the single-attribute time intensity test for the evaluation for sweetness and peppermint flavor. Ten trained time-intensity panellists evaluated the peppermint flavored chewing gum samples varying in the intensity of release of
A trained time-intensity panel was used to evaluate the effect of scale orientation on time-intensity responses. Equi-sweet samples of aspartame, acesulfame k, sucralose and 9% sucralose were presented to 10 panellists for evaluation on both horizontal and vertical scales. For the most part, horizontal and vertical scales yielded similar results. However, Maximum Intensity responses on the vertical scale were approximately
