his International Standard specifies a set of objective tests for familiarizing assessors with sensory analysis. The test methods specified can be useful to: a) teach assessors to recognize tastes and to distinguish between them (see Clause 8); b) teach assessors to know and to familiarize themselves with different types of threshold tests (see Clause 9); c) make assessors aware of their own sensitivity of taste; d) enable test supervisors to carry out a preliminary categorization of assessors. The methods can also be used as a periodic monitor of the sensitivity of taste of assessors who are already members of sensory analysis panels.
