Characterization of product prototype samples to determine uniqueness or a “point of differentiation” from related established products

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)

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

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)

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 control(if it is not different, it must be as good as the control)

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)

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.

Descriptive tests

To determine whether the storage samples are different from the control(if no significant difference is found, product stability is assumed)

To characterize and/or quantify the changes that may have occurred during storage. Used in situations where maintenance of a control is unrealistic.

To determine the relative acceptance of stored products.Acceptance

tests

To classify the samples according to grade standards defined for the product, as well as an evaluation of samples in relation to each other.

To determine which sample is preferred. Preference

tests

To determine recognition of basic tastes.

To determine ability to detect specific variations of the test product and to generate reproducible results.

To determine ability to measure differences and to generate reproducible results.

Sensitivity tests

Difference tests

Descriptive tests

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.
