SENSITIVITY TESTS / SCREENING TESTS

Sensory tests called ‘Sensitivity tests’ or ‘Screening tests’ are asking two main questions: ‘How sensitive are people to sensory characteristics?’ and ‘What is the minimum detectable concentration of a substance?’. These tests aim to screen and to find the best suitable candidates to perform as assessors and sensory experts in specialized sensory tests during products’ evaluation as well as are used to screen regular employees directly responsible for product development and production.

DIFFERENCE TESTS

Difference tests are among the simplest sensory tests. They are based on comparison of samples and are asking ‘Is there any recognisable difference?’. Depending on the test they can be used to test for similarity or difference. Test for difference is used if it is aimed for example to compare one product with that of a competitor and/or to improve a formulation. Test for similarity is used if it is aimed for example to replace an ingredient in the product without being noticed by consumers and/or to maintain consistency in the product.

Mostly used tests:

  • Triangle test
  • Duo-Trio Test
  • Ranking

DESCRIPTIVE ANALYSIS TECHNIQUES

Descriptive techniques are more complex sensory tests and are used to describe differences between products. They are based on comparison of samples and are asking two main questions: ‘What are the sensory characteristics of a product?’ and ‘How can the difference between products be described?’. A small group of well trained people called sensory experts / sensory panel is used to perform them. These tests objectively describe differences between products using list of attributes. Panellists are trained on use of sensory scales for each attribute.

QUANTITATIVE DESCRIPTIVE ANALYSIS METHOD (QDA®)

Quantitative Descriptive Analysis (QDA®) is one of main descriptive analysis techniques used in sensory evaluation. This technique is a behavioral sensory evaluation approach that uses descriptive expert panels to measure a product’s sensory characteristics. Panel members use their senses to identify perceived similarities and differences in products, and describe those perceptions in their own words. Sensory evaluation is a science that measures, analyzes, and interprets the reactions of the senses of sight, smell, sound, taste, and texture of products.
