한국인의 표준미각역치에 관한 연구 = A Study on the Standard Taste Threshold Values of Korean Male College Students

다국어 초록 (Multilingual Abstract)

This study was undertaken to obtain normal mean value of electrogustometric sensitivity threshold for 70 Korean male college students using electrogustometer, and the results obtained were as followed;
1) The mean threshold values of dorsal surface of tongue were as followed:
The threshold value of sweet taste area was 18.20 μA.
The threshold value of salty taste area was 51.20 μA.
The threshold value of sour taste area was 60.91 μA.
The threshold value of bitter taste area was 92.66 μA.
The threshold value of middle taste area was 102.60 μA.
2) The sensitivity of each area of dorsal surface of tongue after treatment with 4% saccharose were increased.
3) The sensitivity of each area of dorsal surface of tongue after treatment with 2.5% sodium chloride were decreased in the middle taste area, increased in the sweet, salty, sour and bitter taste area.
4) The sensitivity of each area of dorsal surface of tongue after treatment with 1% citric acid were decreased in the sour taste area, increased in the sweet, salty, bitter and middle taste area.
5) The sensitivity of each area of dorsal surface of tongue after treatment with 0.075% quinine hydrochloride were decreased in the sour and middle taste area, increased in the sweet, salty and bitter taste area.
6) The taste qualities to electric stimuli were shown electric taste in 56.70%, sour taste in 16.22%, metallic taste in 13.52%, sweet taste in 4.05%, salty taste in 2.70%, bitter taste in 1.35% and others in 5.40%.
