Abstract:
The present invention provides a preparation method and system for clarified plum wine and plum extract, blanching plum at 95° C. for 5 minutes, and then extracting the blanched plum with extracting solution containing 70-75% alcohol in volume ratio of 1:2 (w/v) at 8˜10° C. in vacuum for 30 minutes before centrifugation, cooling clarification of the plum juice at −8° C. and −20° C. is carried out immediately for 30 minutes respectively, so as to obtain clarified plum wine. Afterwards, the plum wine is concentrated in vacuum to ⅕ of original volume to obtain clarified plum extract; therefore, high quality plum wine and plum extract can be obtained without destroying the plum tissue, and the production efficiency is quite ideal.

Abstract:
The present invention provides a preparation method of deglycosylated ginsenosides, which uses the supercritical fluid technology to conduct the deglycosylation of ginsenosides extract in supercritical solvent under preset pressure and temperature conditions. Under the same operational conditions, the deglycosylated ginsenosides extract and solvent at supercritical state are input into an adsorption tank at the preset volume flow rate ratio for the adsorption of ginsenosides. Then, the adsorbed ginsenosides are applied with gradient eluent by using the ethanol solution. Finally, the pressure is lowered for the separation and purification of ginsenosides to get the deglycosylated ginsenosides of high concentration.
