| Research Abstract |
Recently according to an innovation of the social mechanism with the rapidly advanced aging population, extensive countermeasures have been tried in the field of nursing care for those with various systemic diseases, especially with dysphagia. Necessity of the diet care for those with dysphagia is rapidly elevated. Low gel strength agar (LGSA), recently developed as a supplementary food for swallowing was compared with ordinary agar and gelatin. LGSA was developed to have physical properties close to that of gelatin, while keeping one property of agar, i. e. its setting temperature which can be controlled comparatively easier than gelatin. Three samples was prepared with and without orange flavor. After determination of their properties, i. e. hardness, adhesiveness, cohesiveness and gumminess, three samples of two flavor, six in all, were studied for ease of swallowing using electromyography and sensory evaluation, on middle age (40 to 60 years old) and senior age (60~70 years old) subjects. Those experiments revealed nearly the same results with all samples, except for a slight difference in gumminess in LGSA and gelatin. No significant difference in electromyograms were noted in six samples or with age of subjects. It is feasible to employ agar materials together with gelatin in institutions whose members have swallowing disorders.
