Three age groups (30 people each) were examined. Taste stimuli were tested in ionized water. For sucrose and NaCl, speculate on why the results collected from the class differ from those for the 20-39-year-old group results shown in the paper. the conditions under which our lab conducts taste tests may differ from the detection and recognition thresholds of the 90 participants in Thailand. This study used ionized water as a medium for taste stimulation, which may not be the case in classroom data
