Difference Testing

Difference testing is used to identify if there is a detectable difference between products.

Tests are often conducted to:

• Ensure a change in formulation or production introduces no perceptible change in sensory perception
• Substantiate a claim of 'new' or 'improved'
• Confirm that a new ingredient/supplier does not affect the perceived sensory attributes of the product
• Track sensory changes during shelf-life

Difference tests routinely conducted by RSSL's sensory panels include:

• Triangle test
• Duo trio test
• Paired comparisons test
