Sensory Analysis: Triangle Test


Use this test to determine either

• whether the samples are significantly different
• whether the samples are significantly similar.

The method is the same for testing for difference and similarity, but the statistical parameters selected for the evaluation of results and the minimum number of assessors required are different. Typically you need more assessors to test for similarity than to test for difference.

Descriptors: score sheet, number of assessors needed for a triangle test, sample plan for a triangle test, number of assessments, risk of concluding that a significant difference exists when there is none,Maximum number of correct responses, number of panellists, significant difference
