TASTEL & TASTEL+ Description
These systems provide the design of questionnaires, data entry and processing results. Most sensory techniques and their associated statistical treatments were developed in these tools, the list presented below shows the main features:
Preparation of protocols and questionnaires
. Conception and setting up experimental designs
. Complete blocks, Balanced Incomplete Blocks (BIB), Latin Squares, ...
. Preparation of questionnaires
. Editing Word forms to capture deported and consolidated secondary sites.
. Differenciation: A notA test - Pair duo / trio test - Triangle test - 1 of 4 test - 2 of 5 test - Compliance Testing - Taste Tests – Certification tests, ...
. Description: Conventional Profiles – Flash profiles - Free profiles - Napping© profiles - Temporal Dominance of Sensations - Rankings - Compared profiles – Pivot© Profile ...
Data entry in monadic, in comparison, structured and unstructured scales, free or suggested comments
. Appreciation: Product tests on preference scales, with multiple choice, crosstabs, rankings, open questions with free text, date, numeric, ...
. Practicing and training panel: training range tests, comparisons with references ...
. Various graphics: stars, histograms, comparisons, distributions ...
. Nonparametric descriptive statistics: Willcoxon, Friedman, Kramer tests, Mann et Whitney, Kruskal Wallis…
. Analysis of normality: khi2, Kolmogorov Smirnov tests
. Statistics and frequency distribution
. Siginificativity: alpha and beta risks
. Follow up by on product discrimination (triangle tests, conformity) and description (profile)
. Analysis of variance:
2 to 4 factors, balanced, unbalanced, compared to averages Tests PPDS, Duncan, Newman & Keuls, Aspin Welch ...
Factor Factor judge randomly or fixed factor - factors balanced or unbalanced
. Multidimensional statistics and graphs:
Principal Component Analysis: normed & non-standardized on products, assessors, assessors x products with possible additional variables and individuals – significant envelopes
Discriminant analysis, statistical analysis on products, on judges, with or without compromise
Hierarchical Ascendant Classifications on variables, on products, on assessors
Mapping on assessors
. Textual analysis on comments with automatic processing on the basis of occurrences or on synonyms
. Internal Preference Mapping
. External Preference Mapping with different models, with modeling of new products
. Generation of analytical reports based on models of multi-lingual reports, with a possible restitution of all processing and tests listed before, with automatic
selection of appropriate statistics (normal or non-Gaussian) and with automatic interpretations (PCA results, for example).
Panel follow up
. Data entry of panelist characteristics
. Coefficients of presence and accuracy (correct answers, or answers panel)
. Panelists performance Index: discrimination, reproducibility, consistency, consensus
. Training Follow up on references, and summary of training.
The software is available in three languages (French, English, Spanish) and is marketed in more than a dozen countries.
