What is an affective test in sensory evaluation?

An affective test in sensory evaluation specifically measures consumers' preferences, likes, or dislikes regarding a product. This type of test focuses on the emotional responses of consumers, aiming to determine how much they enjoy or favor a particular food or beverage. It often involves subjective assessment tools such as hedonic scales, where participants express their level of preference or satisfaction.

By gathering data on consumers' feelings toward a product, affective tests help producers understand market demands and consumer behavior, ultimately guiding product development and marketing strategies. This is pivotal in sensory evaluation as it directly correlates with consumer acceptance and the likelihood of product success in the marketplace.

In contrast, other types of tests mentioned assess different aspects: procedural tests focus on methods and processes in product development, tests about physical properties evaluate aspects such as texture and aroma, and nutritional tests analyze the health value of food products. Each serves a different purpose within sensory evaluation, but the defining characteristic of an affective test lies in its focus on consumer preference.
