ABSTRACT

Graphic scaling (GS) and magnitude estimation (ME) of hedonic and intensity responses to 4–30% sucrose in lemonade and 0–16% fat in milk gave similar conclusions about the beverages, but GS was simpler to perform and responses were influenced less by numerical and contextural effects. More restricted ranges were used for ME than for GS, and for hedonic than for intensity responses. Good reproducibility was obtained, except for GS of hedonic responses to lemonade, which were bimodally distributed. Use of a higher sucrose reference (R) in lemonade decreased ME values, and increased the intensity exponent from 0.651 when R was 4% sucrose to 0.973 when R was 10% sucrose. Individual intensity exponents varied from 0.068–0.372 for milk, and from 0.146–1.075 for lemonade when R was 4% sucrose, and from 0.373–2.635 when R was 10% sucrose.
