For test subjects both the aged and youth, examination was made on what effects the saliva contained in the bolus of agar jelly, as well as the physical properties of the bolus, had on the swallowing characteristics. The particle size of the masticated agar jelly, and the amount of saliva contained in the bolus of agarjelly, were investigated. At the same time, the amount and apparent viscosity ofsaliva sampled from the aged and youth during a fixed period were measured. The model saliva, which was prepared With xanthan gum, was added to the model crushed agar jelly in three different quantity levels so that three types of the modelmasticated agar jelly could be prepared. Similarly, model saliva adjusted to three different levels of viscosity were added to the model crushed agar jelly to prepare the model masticated agar jelly. The texture properties and swallowing characteristics of each model masticated agar jelly were investigated. No differences between the aged and youth were recognized in the particle size of the masticated agar jelly. The amount of saliva contained in the bolus of agar jelly was 15-35%, and was higher for the youth than for the aged. The hardness and adhessiveness of the model masticated agar jelly decreased with increasing amount of model saliva. The hardness of the model masticated agar jelly decreased with increasing viscosity of the model saliva. As the results of swallowing characteristics, the model masticated agar jelly containing 35% model saliva was easy to swallow for the aged. On the other hand, the model masticated agar jelly containing 25% model saliva was easy to swallow for the youth. No significant difference between the aged and youth was recognized in the swallowing characteristics of the masticated model agar jelly adjusted by adding model saliva with three different levels of viscosity.

对于老年人和青年人这两种受试者，对琼脂胶团中含有的唾液以及胶团的物理性质对吞咽特性的影响进行了检查。研究了粉碎的琼脂凝胶的粒度和琼脂凝胶团中所含的唾液量。同时测定了一定时期内老年人和青年人唾液的量和表观粘度。将用黄原胶配制的模拟唾液以三种不同的添加量添加到模拟琼脂胶中，制成三种不同的模拟琼脂胶。类似地，将调节至三种不同粘度水平的模型唾液加入到模型粉碎琼脂凝胶中以制备模型咀嚼琼脂凝胶。研究了各模型胶冻的质构特性和吞咽特性。在咀嚼的琼脂凝胶的颗粒大小方面，老年人和青年人之间没有差异。琼脂果冻团中所含的唾液量为15- 35%，青年人的唾液量高于老年人。模型咀嚼琼脂凝胶的硬度和粘附性随模型唾液量的增加而降低。模型咀嚼琼脂凝胶的硬度随着模型唾液粘度的增加而降低。从吞咽特性来看，含35%模拟唾液的模拟咀嚼琼脂果冻对老年人来说是容易吞咽的。而含25%模拟唾液的模拟咀嚼琼脂胶则易于青年人吞咽。老年人和青年人之间没有显着差异，确认咀嚼模型琼脂果冻的吞咽特性，通过添加三种不同粘度水平的模型唾液调整。
