Difference from Control Testing, also known as DFC, is the jack-of-all-trades for sensory testing. DFC is a method that can be used for Difference testing, Product Development, and Quality testing. DFC is a rapid sensory quality test that relies on qualified tasters evaluating the test product, in comparison to the Control product. The same test format can be applied to all product categories, including non-food and personal care products.
