Texture concepts for consumers: a better understanding of crispy–crunchy sensory perception

Abstract

Differences in the definitions and terms used by consumers to describe their sensory sensations of crispness/crunchiness were studied, highlighting the relevance of using well-defined terms in consumer studies. A questionnaire was presented to consumers from two different Spanish-speaking countries (Spain and Uruguay, n = 200). The answers showed that the terms crispy and crunchy had different meanings or evoked different perceptions depending on the country. The crispy/crunchy food items most frequently mentioned by consumers were dry-crisp, processed products; vegetables or other wet-crisp products were not often mentioned by the consumers interviewed. The main difference between the two countries was that 38% of Spanish consumers did not know the Spanish term for “crunchy” and 17% thought that “crispy” and “crunchy” had the same meaning. The results contribute to a greater knowledge of the terminology used by the consumers to describe oral sensations related to crispness and crunchiness.
