Both the scale’s and the sample’s presentation order were balanced among the consumers. Eighty consumers evaluated five samples of orange juice using the four above-mentioned scales. This study compared the performance of the “hybrid hedonic scale”, the nine-point hedonic scale, the self-adjusting scale and the ranking scale with respect to: (i) the variability of sensory responses, (ii) discriminating power, (iii) adequacy of the data with ANOVA assumptions and, (iv) ease of use. It is thus important to identify alternative scales, presenting better performance than the traditional hedonic scale. However, several researchers believe that this scale presents limitations, which decrease its discriminative power. In consumer tests, the nine-point hedonic scale has been widely employed for data collection.
