What is a key limitation of sensory evaluation methods?

The key limitation of sensory evaluation methods lies in the subjectivity that can introduce variability in results. Sensory evaluation relies heavily on human perception, which can differ significantly between individuals due to personal preferences, experiences, and physiological differences. This subjectivity can lead to inconsistent results, making it challenging to achieve reliable and reproducible outcomes. For instance, what one panelist finds appealing, another might find unappealing, affecting the overall evaluation of a product and its subsequent development decisions.

While other challenges such as costs, recruitment issues, and the range of product types do exist, they are more situational compared to the inherent variability brought about by personal subjectivity, which directly influences the validity of the sensory evaluation.
