Sensory Testing


A consumer's direct sensory experience with a product often plays a major role in that product's market success. In order to minimize returns and maximize repeat purchases, it is crucial that a product's attributes accurately match the sensory cues delivered on product packaging and marketing collateral and meet consumer expectations. UL sensory testing services evaluate product difference, characteristic and preference attributes in order to help companies understand how their products are perceived by their target markets.


Utilizing both expert analysis and consumer feedback, UL's sensory testing services help companies evaluate whether their products meet consumers' preferred sensory characteristics. Our customers gain a detailed view of consumers' responses to a tested product and a deeper understanding of that product's prospective competitive value.


Industry knowledge, analytical expertise and technical skill come together in UL’s state-of-the-art facilities to evaluate how tested products will influence consumer purchase decisions and build brand loyalty.
