PROP sensitivity
Higher PROP intensity scores were associated with higher liking
for the tomato juice sample containing 640 mg at the initial taste
test (r = 0.24; p = 0.03). At the final taste test this same association
persisted among subjects in the gradual group (r = 0.24; p = 0.15),
but not among subjects in the abrupt salt reduction group
(r = 0.05; p = 0.74). Higher PROP intensity scores were associated
with higher perceived saltiness of the sample containing 640 mg
sodium at the initial taste test (r = 0.26; p = 0.02). At the final taste
test, higher PROP intensity was associated with higher perceived
saltiness of the samples containing 472 mg (r = 0.37; p = 0.02)
and the 640 mg sodium (r = 0.26; p = 0.14) among subjects in the
gradual group only. There was no association between PROP inten-
sity and perceived saltiness intensity of the samples containing
136 mg and 304 mg sodium at either the initial or final taste tests,
for either the abrupt or gradual salt reduction group
