Crispiness or crispness is one of the most common food texture attributes.[1] Crispiness refers to a hard food that emits a sound upon fracturing.[2] Foods described as crisp tend not to show signs of deformation prior to fracture. Crispiness and crunchiness are often used interchangeably, however crispiness tends to be associated with a higher pitched sound, while crunchiness is associated with lower pitched sounds.
