What is sensory evaluation? Sensory evaluation is a scientific discipline that analyses and measures human responses to the composition of food and drink, e.g. appearance, touch, odour, texture, temperature and taste. In schools it provides an ideal opportunity for students to evaluate and give feedback on their dishes, test products and experimental designs. The precise way in which sensory

    Hedonic scales are well tried and tested in consumer research for capturing liking data (Stone and Siddel, 1985). Figure 8.5 shows a typical example of a nine-point hedonic scale, a version regularly used with consumers in preference mapping studies to capture liking scores. What is sensory evaluation?

    9-Point hedonic scale Labeled hedonic scale Context effect abstract In recent years, interest in measuring hedonic responses has grown tremendously in both basic psycho- physics and applied food and consumer research, resulting in the development of several new hedonic scaling methods. With these developments have come questions about theoretical and practical differ-ences among the … Data obtained from the sensory evaluation indicated that the mean score for taste, color, flavor, texture and overall acceptability were generally high for biscuit containing 5% lentil flour.

Development in flavor and texture of soy milk yogurt needs a grouping of treatments. The present study employed some treatments including thermal, added flavor essence, sweetener, and animal's milk-based products to develop soy milk yoghurt.

    There have been several extensions of the 9-point hedonic scale. Kroll (1990) 4 showed that a scale with nine “child friendly” verbal anchors ranging from “super good” to “super bad” performed better with 5-10 year old children than either the original 9-point scale or a scale utilizing “smiley” faces. Hedonic scales are well tried and tested in consumer research for capturing liking data (Stone and Siddel, 1985). Figure 8.5 shows a typical example of a nine-point hedonic scale, a version regularly used with consumers in preference mapping studies to capture liking scores.

    semantic, quantitative, and statistical advantages over the 9-point hedonic scale. Key words: category-ratio scale, labeled hedonic scale, magnitude estimation, 9-point hedonic scale Introduction The measurement of hedonic responses is fundamental to understanding the relationship of the chemical senses to food preference and selection. Despite Sugar and fat: Sensory and hedonic evaluation of liquid and solid foods. PHYSIOL BEHAV 45(1) 177-183, 1989.--Twenty-five subjects evaluated the sweetness, creaminess and fat content of liquid and solid dairy products containing between 0.1 and 52 g fat/100 g and sweetened with 0-20% sucrose weight/weight. Liquid stimuli included skim milk

    BOOTSTRAPPING PENALTY ANALYSIS IN SENSORY EVALUATION OF PIZZA PRODUCTS by Catherine E. Estiaga ABSTRACT Penalty analysis is a popular method used to evaluate data from sensory evaluation using the Just About Right Scale and the Hedonic Scale. Although the test estimates the mean drops for the “Too Little” and “Too Much” categories of Data from nine previous sensory studies utilizing scales varying from 5 to 15 points were normalized by calculating z values to estimate the position of categories on the psychological continuum. Normalized data from studies utilizing a 5‐point scale for sensory evaluations were nearly equally spaced as is assumed for many statistical
