Thicken water made with thickener and saccharin granules as solvent is placed in the nasal cavity and saccharin time is measured.
Nectar-like thickened water (with low viscosity) and honey-like thickened water (with high viscosity) were prepared using a starch-based thickening agent (Thick&Easy, Hormel) or xanthan-gum-based thickening agent (Thicken Up Clear, Nestle). This resulted in a total of four types of thickened water samples. The nectar-like and honey-like thickened water samples were prepared according to the methods specified by the manufacturer.
3 mg of saccharin and 8 mg of colorant (green food dye, Kyoritsu Foods Co., Ltd.) were dissolved in 1 ml of purified water or one of the four types of thickened water samples, resulting in five types of saccharin solutions: 1. a solution without a thickening agent, 2. a starch-based nectar-like solution, 3. a starch-based honey-like solution, 4. a xanthan-gum-based nectar-like solution, and 5. a xanthan-gum-based honey-like solution.
The subjects were asked to participate in the study for any three days during the study period. The saccharin time was measured using one type of saccharin solution on the first day and two types on each of the second and third days. At the time of each measurement, one of five types of saccharin solutions was randomly assigned so that all the five types would be tested individually.

We examined the effects of different types of thickening agents and viscosities of thickened water samples on the mucociliary transport function. The results revealed that the thickened water samples with high viscosity may take longer to be discharged via the mucociliary transport function, while there is no difference in the time of discharge between the thickened water samples with different types of thickening agents.
