- Scope
- This standard specifies a procedure for determining whether there is a perceivable sensory difference or similarity in the intensity of sensory properties between samples of two products. This standard is applicable to the differences in a single sensory characteristic or several characteristics, which means that for a known characteristic, it can determine whether there is a sensory difference and identify the range of the difference, but it cannot give an explanation of the degree of difference. The absence of a difference in properties in the evaluation does not mean that there are no differences between the two products. This standard applies only to relatively homogeneous products. This standard applies to the following situations: a) Determination - whether there is a sensory difference (paired difference test); - whether there is no sensory difference (paired similarity test), for example, when ingredients, processes, packaging, handling or storage When improving. b) Selection, training, and testing The evaluator should know before carrying out the test whether the test is a one-sided test (the test supervisor knows the range of the difference in advance, and the alternative hypothesis is equivalent to the existence of the difference within the expected range) or a two-sided test (the test supervisor knows in advance the range of the difference). The extent of the difference involved is not known, and the alternative hypothesis amounts to a difference in one or the other). Pairwise tests are also useful for comparing two products based on preference. Different examples of pairwise tests are shown in Figure B.1.
