title: Test-Retest Reliability of Detection Time Data Measured Using a Masseter Electromyogram in Healthy Young Adults: Preliminary Analysis of Data.
abstract: Few studies have assessed test-retest reliability of flavor detection time in semisolid and solid foods. In this study, test-retest reliability was assessed in 16 healthy young adults (22.6 ± 5.5 years old) on the data collected using a masseter electromyography-based system between two experimental sessions approximately 35 days apart. The overall correlation coefficients were calculated across five test foods; the correlation coefficient for the entire sample was statistically significant. Five correlation coefficients were calculated for individual test foods, but only orange-flavored gummy candy was significantly correlated across the two sessions. These results suggested that flavor detection time measured by the electromyography-based system is basically reliable over time, with considerable variation among flavors.
