个体的咀嚼性能可以通过描述粉碎的测试食物颗粒的大小分布作为咀嚼击打次数的函数来量化。采用标准化的筛选方法和标准化的人工试验食品(Optosil)获得重复性结果。一些测量是用花生进行的。粉碎食品的粒度分布可用7个参与个体的Rosin-Rammler分布函数来描述，该函数用中位数粒度(x_(50))和分布的宽度(B)来表征粒度分布。宽度变量b几乎不依赖于咀嚼笔划的数量，并且个体之间的b差异很小。在给定的咀嚼次数下，受试者之间观察到的中位颗粒大小有相当大的差异，这反映了测试食物粉碎效率的差异。对于所有受试者，根据x50=c次的关系，中位颗粒大小作为咀嚼笔划次数N的函数而减小。然后。变量c和d表征了受试者交流的效率。
The masticatory performance of an individual may be quantified by describing the size distribution of particles of a comminuted test food as a function of the number of chewing strokes. A standardized sieving method and a standardized artificial test food (Optosil) were used to obtain reproducible results. Some measurements were performed using peanuts. The distribution of particle sizes of the comminuted food was adequately described by a Rosin-Rammler distribution function for the 7 participating individuals which characterizes the size distribution by the median particle size (x50) and the broadness of the distribution (b). The broadness variable b hardly depends on the number of chewing strokes, and the differences in b between the individuals are small. Considerable differences in the median particle sizes at a given number of chewing strokes were observed between the subjects, reflecting differences in efficiency of comminution of a test food. For all subjects, the median particle size decreased as a function of the number of chewing strokes N according to the relation, x50 = c .times. Nd. Variables c and d characterized the efficiency of communition by the subjects.
