The purpose of the test was to detect gross abnormalities
in tasting ability and measure perceived
intensity and taste quality on the four basic taste
modalities. High, medium, and low concentrations
were used. The lowest level of each tastant compound
exceeded the level at which it would be normally
recognizable (Pribitkin et al., 2003). The taste stimuli
were made from premeasured compounds dissolved
in distilled deionized water. The taste stimuli used in
the current study were as follows: sucrose for sweet,
sodium chloride for salty, citric acid for sour, and
quinine hydrochloride for bitter.
