Sensory analysis - difference tests

Validate any sensory salient changes in your product! We offer a selection of difference tests with a trained analytical panel. 

Cause

Evaluate if the sensory experiences such as taste, flavor or touch of a product differs with storage time or a change of an ingredient. 

The most effective method to evaluate potential changes is to use a trained and selected panel of humans. RISE has a long experience of these kind of tests and unique abilities to combine the results with technical measurements. 

Sensory difference tests are good for 3 kinds of questions: 

  1. If you would like to change a component or ingredient in a product and do not want this to be noted by the consumer. 
  2. If you would like to change a component or ingredient in a product and ensure that this change is notable by the consumer.
  3. To evaluate how storage affects your product. 

Method

Dependent on product and the purpose of the measurement there are four common difference tests: paired comparison, duo-trio-test, triangle test and difference-from-control. All methods are evaluated according to standard procedure. 

The measurement is conducted in a sensory laboratory using 8-12 trained and selected judges from the RISE analytical panel. 

Deliveries
