使用健康年轻人作为评估者和物理性质明显不同的半流质食品作为样本，对两次感官分析的结果进行了比较。一项分析要求评估人员仅通过口腔感知来感知食物质地，并将其用作预测丸剂样品吞咽难易程度（即样品通过咽部的流动性）的基础，而无需实际吞咽样品。另一项分析要求评估人员通过实际吞咽来评估丸剂样品通过咽部的流动性。结果的比较表明，人类通过在口腔中感知食物的质地来预测吞咽丸剂的难易程度（即丸剂通过咽部的流动性）。还对通过感觉分析获得的丸剂通过咽部的流动性的评价与通过视频荧光成像获得的丸剂样品的通过速度和通过时间之间的关系进行了检查。人们认识到，对于柔软且易于吞咽（因此易于通过咽部移动）的半流质食品样品，前端速度较快，而对于坚硬且难以吞咽（因此被认为难以通过咽部移动）的半流质食品样品，前端速度较慢。这些发现表明，人类对半流质食品吞咽难易程度的感知与丸剂的前端速度密切相关。无论是丸剂样品的尾端速度，还是丸剂样品从前端到尾端的通过时间，样品之间都没有发现显着差异。这些结果意味着，通过某种吞咽努力，健康个体正在控制物理性质明显不同的丸剂通过咽部的时间，从而使时间保持恒定。
The results of two sensory analyses, using healthy young individuals as assessors and semiliquid foods with markedly different physical properties as samples, were compared. One analysis required the assessors to perceive the food texture by oral perception alone and to use it as a basis for predicting the ease of swallowing of the bolus samples (i. e., the mobility of the samples through the pharynx) without actually swallowing the samples. The other analysis required the assessors to evaluate the mobility of the bolus samples through the pharynx, by actually swallowing them. Comparison of the results implied that human beings predict how easy it is to swallow a bolus (i. e., the mobility of the bolus through the pharynx) by perceiving in the oral cavity the texture of the food. Examinations were also made on the relationship between the evaluation of mobility of the bolus through the pharynx obtained by sensory analyses, and the transit speed and passing time of the bolus samples obtained by videomanofluorography. It was recognized that the front end speed was fast for semiliquid food samples that were soft and easy to swallow (and therefore easy to move through the pharynx), whereas the front end speed was slow for semiliquid food samples that were hard and difficult to swallow (and therefore perceived as being difficult to move through the pharynx.) These findings suggest that human beings’ perception of the ease of swallowing of semiliquid food is closely related to the front end speed of the bolus. No significant difference was found among samples, either in the tail end speed of the bolus samples, or in the passing time from the front end to the tail end of the bolus samples. These results imply that, through some kind of swallowing efforts, healthy individuals are controlling the passing time through the pharynx of boluses with markedly diflerent physical properties, so that the time remains constant.
