About This Item
Full Description
The "A" - "not A" test can be used in sensory analysis in the following ways:
- a) as a difference test, particularly for evaluating samples having variations, for example, in appearance (making it difficult to obtain strictly identical repeat samples) or in aftertaste (making direct comparison difficult);
- b) as a recognition test, particularly for determining whether an assessor or group of assessors identifies a new stimulus in relation to a known stimulus (for example, recognition of the quality of the sweet taste of a new sweetener);
- c) as a perception test, to determine the ability of an assessor to discriminate stimuli.
Examples of its application are given in Annex B.
