Descriptive Test

Descriptive Test
Descriptive test are usually carried out by a small group of highly trained panelists.

They are specialized difference tests where the panelists are not simply asked whether they can determine differences between the two products, but are asked to rate particular aspects of the flavor or a particular product on a scale.

Flavor aspects vary depending on the type of product being studied.

For example, flavor note in tea may be bitter, smoky, and tangy, whereas flavor notes in yoghurt may be acid, chalky, smooth and sweet.

A descriptive “flavor map” or profile of a product is thus developed.

Any detectable changes in the product would result in changes in the flavor map.

The training required to be able to detect, describe and quantify subtle changes in specific flavor notes is extensive.

Therefore, establishment of such panels is costly. When trained the panelists function as analytical instruments and their evaluation of a product is not related to their like or dislike of it.

The descriptive taste panel work is useful to research and development scientists, because it gives detailed information on the types of flavor differences between products.
