Abstract
AbstractGustatory ability is an important marker of health status, including COVID-19 disease. We compare self-reporting with home and lab psychophysical “taste strips” tests in healthy subjects. The taste test consisted of paper strips impregnated with sweet, bitter, salty, or sour tastants, and with the trigeminal stimulus capsaicin, each in high and in low concentration. The test was carried out either in a controlled lab environment (74 participants, 47 women) with the strips being administered by the experimenter or self-administered by the participants at home (77 participants, 59 women). After self-reporting their subjective assessment of chemosensory ability, the participant identified the taste of each strip and rated intensity and pleasantness.Identification score, intensity, and pleasantness averaged over the 8 taste strips were similar between the lab and the home-administered tests. Self-rated taste ability did not correlate with any of these scores, but strongly correlated with self-rated smell ability in the lab group (r=0.73), and moderately correlated in the home group (r=0.51). Taste identification correlated with intensity ratings (r=0.63 lab, r=0.36 home) but not with the pleasantness ratings (r=-0.14 lab, r=0.1 home).The results of the taste strips test were similar in the lab and at home for healthy young participants and provide a baseline against which taste tests can be compared in future applications.
