我们分析了在自由进食和自然食物条件下，从进食到最后吞咽咀嚼和吞咽的口腔行为。使用视频透视技术，对5名“自由进食的受试者”进行了测量，包括下颌骨和舌头的运动，张口的大小，吞咽动作中涉及口腔方面的不同序列，以及团状物的大小和运动。在进食过程中，舌头向前和向后移动，将食物送入口腔，将食物压在硬腭上，并将食物输送到磨牙的咬合面。大部分食物在第一次吞咽时被吞下，任何剩余的食物都被舌头聚集成一团，然后在最后一次吞咽。这些发现表明：1)舌法在识别和评估被咬食物的量中起着重要作用；2)食物在口腔内的压缩在食物质地识别中起着重要作用；3)第一阶段运输与质地识别过程密切相关；4)人在自由进食食物时至少需要两口燕子，即使一口食物也是如此；5)口腔阶段的吞咽持续时间可能取决于口服量，并且与吞咽指令下的测量结果不同，对于较小体积的食物，吞咽的持续时间更长。
We analyzed oral behavior from food intake until terminal swallow for mastication and swallowing under a freely eating condition with a natural food. Measurements, including movement of the mandible and tongue, the size of the gape, different sequences involved in the oral aspect of the swallowing action, and bolus size and movement were carried out in five “freely eating subjects” using videofluorography. During food intake, the tongue moved forwards and backwards to introduce food into the mouth, to compress the food against the hard palate, and to transport food to the occlusal surface of the molar teeth. Most of the food was swallowed in the first swallow, and any residual food was aggregated by the tongue into a bolus and then swallowed in the last swallow. These findings suggest that 1) tongue manipulation plays an important role in recognizing and evaluating the volume of bite taken, 2) the intra-oral compression of food has a role in the recognition of food texture, 3) stage I transport is closely bound to the texture recognition process, 4) humans need at least two swallows, even with one bite of food, when ingesting food freely, and 5) the duration time of the oral stage of swallowing may depend on the bolus volume and be longer for smaller volumes unlike those measured under the command swallow.
