Abstract
It is intended to provide a method for producing aglycone from a glycoside efficiently at low cost without using an acid catalyst or an organic solvent. The method for producing aglycone, characterized by bringing a glycoside into contact with high temperature high pressure water. The temperature of the high temperature high pressure water is generally from 100 to 374° C., preferably from 140 to 320° C., more preferably from 200 to 300° C. The pressure of the high temperature high pressure water may be not lower than the saturated water vapor pressure at the temperature, i.e., a pressure at which the liquid state is maintained.
Claims5
A method for producing aglycone by bringing an O-glycoside into contact with high temperature high pressure water, characterized in that the high temperature high pressure water has a temperature from 150 to 320° C. and has a pressure not lower than a saturated water vapor pressure corresponding to the temperature provided that said temperature is from 240 to 320° C. in the case that the glycoside is soybean saponin.
