Outline of Final Research Achievements

The present study used as basic bread porridge sample, which was prepared with bread, liquid food whose milk solution content was partially replaced with salad oil, and native gellan gum as gelling agent. This study was investigated that the sample added semi-liquid foods to the surface of the bread porridge, and examined how it affected the condition of swallowing by the person consuming the sample in this study. The subjects evaluated at 20℃sample added semi-liquid foods to the surface as “less sticky in the mouth, and easier to eat” compared the basic bread porridge sample. Hardness of the sample temperature at 20 ℃ was shown to be significantly softer in bolus form in the mouth. The basic bread porridge sample at 45℃ was found to have shorter muscle activity duration during swallowing, compared with the sample at 20℃. The result of the endoscopic examination of swallowing was found to differ by subjects.
