| Outline of Final Research Achievements |
Improvement of meal aid for elderly people is one of the major issues in basic nursing science. In Japan, rice gruel is a common meal for the elderly who need support for eating, scooped up from the bowl to their mouths by helpers. The risk of misswallowing during eating increases with laps of the time because the rice gruel liquefies gradually. Our previous research clarified that rice gruel is dissolved and liquefied in the bowl by Alpha-Amylase (sAA, hereafter) in saliva from the elderly. However, no information was available for the function of saliva collected from different generations and genders. In this project, we carried out a series of physiochemical experiments, and quantified the activity values of the sAA among those of healthy men and women of sixties and twenties. It was demonstrated that the activity value of sAA for elderly men and women are higher than those for young men and women, suggesting that the risk of misswallowing for the elderly is very high.
