Association of pH with Appeal and Sensory Attributes

Outcome Linear trend Quadratic trend
𝛽 (95% CI) p-value 𝛽 (95% CI) p-value
Appeal Liking −2.8 (−3.5, −2.0) < .001 −1.0 (−1.9, −0.1) .035
Disliking 3.4 (2.6, 4.2) < .001 1.3 (0.4, 2.3) .008
Willingness to use again −2.7 (−3.6, −1.9) < .001 −1.4 (−2.4, −0.5) .006
Sensory attributes Sweetness −2.3 (−3.1, −1.6) < .001 −0.9 (−1.8, −0.9) .035
Smoothness −4.6 (−5.4, −3.8) < .001 −2.4 (−3.3, −1.5) < .001
Bitterness 3.3 (2.6, 4.0) < .001 2.0 (1.1, 2.8) < .001
Harshness 5.2 (4.4, 6.0) < .001 3.3 (2.3, 4.2) < .001

Note. Models controlled for flavor. P-values were corrected for multiple testing to control the false-discovery rate using the Benjamini-Hochberg procedure.
