Mochiis highly cohesive and adhesive, and easy to choke on. Many of the fatal suffocation accidents with mochioccur in the elderly aged 65 years or older. These circumstances prompted us to investigate a special property of waxy wheat which is similar in texture to waxy rice, but is less cohesive and adhesive. We compared the differences in chewing and swallowing movements associated with eating waxy rice mochiand waxy wheat mochibetween healthy adults and healthy elderly. Healthy elderly chewed mochimore and longer than healthy adults. Although there was no difference in the number of chewing cycles or total duration of chewing between the two types of mochi, waxy wheat mochiwas easier to chew and left less pharyngeal residue. These findings lead us to suggest that waxy wheat mochiis promising as a food that is easy to swallow and difficult to choke on.
