    IMPORTANCE OF REFERENCE STANDARDS IN TRAINING PANELISTS (1986)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of sensory studies 1 (1986), S. 0

    Notizen: When training a sensory evaluation panel, reference standards play an important role in developing appropriate terminology, establishing intensity ranges and showing the action of an ingredient. In addition, use of reference standards reduces the amount of training time while providing documentation for terminology. Product characteristics can be demonstrated through reference standards for application in plant quality assurance programs as well as for project planning in new product development, product maintenance (i.e., shelf-life), product improvement and cost reduction programs.

    EVALUATION AND APPLICATIONS OF ODOR PROFILING (1986)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of sensory studies 1 (1986), S. 0

    Notizen: An odor profiling procedure was developed based on the ASTM odor profiling method. This modified procedure involved using approximately twenty panelists. Panel sessions and data collection were controlled by computer. The results obtained by this panel compared favorably to results obtained by the ASTM panel for which 150 panelists evaluated each compound, indicating that a small panel can be used to produce replicable results. Statistical methods of finding similarities and dissimilarities among compounds using profile data are discussed and compared to results from a multidimensional scaling (MDS) study in which degrees of differences among compounds were judged directly. These results indicate that profile data can be used to define and map the degree of similarity/dissimilarity among compounds, as well as to define the sensory dimensions on which these compounds differ. The use of factor analysis to study the underlying sensory dimensions of the odor space is also discussed. It is hoped that this type of research will lead to a better understanding of the underlying dimensions used to describe odorants.

    COMPONENT AND FACTOR ANALYSIS APPLIED TO DESCRIPTORS FOR TEA SWEETENED WITH SUCROSE AND WITH SACCHARIN (1986)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of sensory studies 1 (1986), S. 0 
    Details

    Notizen: Component and factor analysis were compared as means of reducing scaled values for 10 descriptors of tea to two dimensions so that relations among the attributes could be visualized. The association diagrams yielded by the two methods were generally similar, and there were significant differences between the diagrams for English Breakfast, an 80:20 blend of English Breakfast and Sencha teas, Ceylon and Darjeeling teas. Bartlett's test for equality ofvariance-covariance matrices was significant. When tea was equivalently sweetened with sucrose and with saccharin, the association diagrams were different. Preference and sweetness were highly correlated with each other and they had high com-munality with the other attributes when saccharin was the sweetening agent. When sucrose was the agent, sweetness still had high communality with the other attributes, but preference did not, indicating preference was the result of interplay of all the attributes rather than a dominant one. The correlation matrices were not significantly at p= 0.05, but they were at 0.10.

    COMPARISON OF RATING SCALES: SENSITIVITY, REPLICATES AND RELATIVE MEASUREMENT (1986)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of sensory studies 1 (1986), S. 0

    Notizen: The relative sensitivities of four scaling methods were assessed in central location tests with untrained judges. The scales included category scales, line scales, magnitude estimation, and a hybrid of the line and category scales. Approximate parity was observed among category scales, line scales and the hybrid scale in their ability to differentiate small physical differences. Magnitude estimation was used as efficiently as the other methods by a college population, but less efficiently by a heterogeneous sample of consumers. Judges used the scales with greater accuracy as they became familiar with the range of products to be judged. In spite of relatively small physical differences, subjects used wide ranges of the scales, supporting the view that rating scales are relative, not absolute, measuring instruments.

    SOME SOURCES OF BIAS IN CONSUMER TESTING (1986)
    Oxford, UK : Blackwell Publishing Ltd

    Notizen: Data sets from three studies were examined to determine the effects of brand identification and package design on consumer responses during product evaluation. In these studies, consumers evaluated products with or without brand identification, compared products in standardized conditions, and compared products in different package designs with different or identical product contents. Measurement of consumer responses for all studies was based on 9-point hedonic scale. The results of the study showed that consumers were less critical in their evaluation when the samples being assessed were identified by brand names. Brand identification and package design, when not concealed in the comparison of product contents, resulted in consumer response bias. Also, the popularity of a brand influenced consumer's perception of products.

    EVALUATION OF THREE SCALING METHODS FOR HEDONICS (1986)
    Oxford, UK : Blackwell Publishing Ltd

    Notizen: A collaborative study of twenty-three laboratories was conducted to compare the relative effectiveness of three scales: two forms of magnitude estimation scaling and one form of a category scale in the measurement of hedonic response to a controlled stimulus. Responses from 553 individual judges show that all scales yield hedonic measurements that are very similar in both direction and magnitude of difference between the stimuli. No scale showed any clear superiority in reliability, precision, or discrimination. Selection of a scale must be based on considerations other than the simple form of response.

    COMPARISON OF SENSORY PROFILES DONE BY TRAINED AND UNTRAINED JURIES: METHODOLOGY AND RESULTS (2003)

    Notizen: We compare the sensory profiles of six dark chocolates done by two types of juries: some trained juries and an untrained jury. Six laboratories, each one made up of 10 to 15 judges, are regarded as trained juries since the assessors were well trained before the evaluation of the products. The second type of jury is composed of only one panel of 29 untrained assessors and this jury is named the untrained jury. Fourteen attributes were evaluated and analyses of variance have been carried out by attribute to compare the sensory profiles of the six chocolates done by the trained juries and by the untrained jury. These analyses of variance show that the two types of juries give similar sensory profiles and that the few differences are mainly due to different ways of using the scale.

    Notizen: Consumers unfamiliar with passion-fruit juice were presented with 24 computer generated package images on which six packaging factors (background color, picture, information, brand, language and shape) had been manipulated and asked to give scores for six expected sensory attributes (sweetness, pureness, sharpness, refreshing, freshness, naturalness) and liking. Significant effects were obtained for each attribute, with background color and information being the most important. Consumers varying in Need For Cognition (NFC) were affected differently by the investigated features of the package. High NFC individuals used less of the packaging factors than low NFC subjects did.
