Effects of moderate exercises on preference for organic acid solutions added with citric, malic or tartaric acid with or without glucose were investigated by the sensory evaluation using a 9-point hedonic scale and a panel of 45 assessors. The concentrations of organic acids were 0.0024M, 0.0096M and 0.0288M and that of glucose 3.8%. There were no significant pre-exercise differences in preference (p＞0.05) among citric, malic or tartaric acid solution of the same concentration. Preference for 0.0024M and 0.0096M organic acid solutions except citric acid significantly (p＜0.05) increased after 30 minutesexercise using a bicycle ergometer at 130/min. heart rate. Preference for 0.0024M, 0.0096M and 0.0288M citric acid solution or 0.0288M malic or tartaric acid solutions did not change significantly after 30 minutesexercise (p＞0.05). By glucose addition, pre-or post-exercise preference for 0.0024M and 0.0096M citric, malic or tartaric acid solutions except 0.0288M over all organic acid solutions significantly (p＞0.05) increased as compared with organic acid solution of the same concentration without glucose. Preference for every organic acid solution with glucose did not increase after 30 minutesexercise (p＞0.05). There was no organic acid with or without glucose post-exercise preference for which was significantly higher than that for other organic acids (p＞0.05).
