Question

Provide some examples of applications of different tests and hedonic sensory tests. (Analytical tests, triangle test, duo-trio test)

Answer 1

The applications of analytical tests are:-

• EDS and SEM are used to examine and analyze defects in products.
• These are used to determine the composition of the elements of foreign materials.
• These help in analyzing the coating's thickness.
• These help to determine the particle and grain size for various industries like microelectronics, food processing, general manufacturing, etc.

The applications of the triangle test are:-

• It helps in gauging or measuring the difference between the two products.
• They select fitted panelists for a specific test.
• They determine whether ingredients or processing shifts have remarkably changed a product or not.

The applications of the duo-trio test are:-

• It is a difference test that determines if the sensory difference exists between two samples or not.
• This method is used to determine whether the difference between the products is a result of the change in processing, ingredients, storage, or packaging.

The applications of hedonic sensory tests are:-

• This test is used in food preference surveys and consumer testing.
• The coveted goal of effective sensory evaluation testing is the capacity of tests to distinguish samples on the principle of scale data. The commonly used scales are preference testing and food acceptability.
