高速液体クロマトグラフを用いた清涼飲料水中の糖成分の定量

High-performance Liquid Chromatography was used to measure sugars in beverages, canned soft drinks and carbonate beverages. A Asahipak NH2P-50 column (250×4.6mmI.D.) was eluted with aceto-nitrile: H_2O=77:23(v/v) at a flow rate of 1.0ml/min. Fructose was eluted at about 10min, glucose at about 14min and sucrose at about 23min

味覚と運動 : 官能検査手法の検討

Some method of sensory evaluation was studied, in order to investigate the effect of exercise on taste. Especially sweet taste. From the method of triangle test, some of factor cased to disturb for the test. The mesurement of detection threshold from the method of limits, this method was carried out without any problem still of complicated tequniques, the stable data was got by this method. These results suggests the measurement of detection threshold from the method of limits can be used for the investigation of the effect of exercise on taste
