Technical Abstract: The textural attributes of crispness and crunchiness are important factors in the enjoyment of many foods, but they are defined differently among dictionaries, consumers, and researchers. Sensory, mechanical, and acoustic methods have been used to provide data on crispness and crunchiness. Sensory measurements include biting force and sound intensity. Mechanical techniques resemble mastication and include flex, shear, and compression. Acoustical techniques measure frequency, intensity, and number of sound events. Water activity and oil content contribute to crispness and crunchiness, which also have temporal aspects. Information in the literature is compared in this paper to develop unambiguous definitions of crispness and crunchiness.
