Type of Applications New Product Development Product Matching Product Characterization of product prototype samples to determine uniqueness or a “point of differentiation” from related established products New Product Development Evaluation of the experimental prototype samples to establish whether differences exit among them (or between the prototype samples and a standard) Determination of whether the prototype samples meet the acceptability requirements established for the product (e.g., whether they are equal to or better than the standard) Product Matching To verify that there is no difference between the standard and the experimental product, and that the two have equivalent acceptability. To determine whether the experimental product is different from the control (if it is not different, it cannot be better) Difference tests Product Improvement If products differ, to establish whether the experimental product is liked more than the control (e.g., represents an improvement) Affective tests To determine whether the experimental product is different from the control (if it is not different, it cannot be poorer) Difference tests Process Change Affective tests If products differ, to establish whether the experimental product is liked as well as or more than the control Cost Reduction Difference tests To determine whether the experimental product is different from the control (if it is not different, it must be as good as the control) Descriptive tests Selection of a New Source of Supply If products differ, to establish whether the experimental product is liked as well as or more than the control To determine whether the experimental product is different from the standard (if it is not different, it must be as good as the standard) Difference tests Quality Control Descriptive tests If sample is found to be different, to indicate how the sample differs from the standard. Results of these tests may be used to guide remedial action, such as changes in processing procedures. To determine whether the storage samples are different from the control (if no significant difference is found, product stability is assumed) Difference tests Storage Stability Descriptive tests To characterize and/or quantify the changes that may have occurred during storage. Used in situations where maintenance of a control is unrealistic. Acceptance tests To determine the relative acceptance of stored products. Category scoring or ratio scaling Product Grading or Rating To classify the samples according to grade standards defined for the product, as well as an evaluation of samples in relation to each other. Consumer Acceptance and/or Opinions. Acceptance tests Whether the current product can be marketed or improvement is needed. Consumer Preference Preference tests To determine which sample is preferred. Sensitivity tests To determine recognition of basic tastes. Panelist Selection and Training Difference tests To determine ability to detect specific variations of the test product and to generate reproducible results. Descriptive tests To determine ability to measure differences and to generate reproducible results. Correlation of Sensory with Chemical and Physical Measurements To know how any chemical or physical method used compares with the human senses, I.e., the panel’s ability to detect and quantify sensory characteristics. Descriptive tests with trained panelists
