Embodiment 1

[0022] 1) Soak and decoct Luo Han Guo in water 6 times its weight to obtain water extract A;

[0023] 2) Soak and decoct Luo Han Guo in water 8 times its weight to obtain water extract B;

[0024] 3) Merge and filter A and B;

[0025] 4) Concentrate the filtrate, and use D101 styrene copolymer macroporous adsorption resin to absorb the filtrate for decolorization;

[0026] 5) Wash the adsorbed decolorized resin until it is colorless, then elute it with an ethanol solution with a concentration of 75-80%, and collect the eluate;

[0027] 6) Concentrate the eluate, and use Al 2 o 3 The column adsorbs the eluent for deodorization;

[0028] 7) Filtrating, recovering the ethanol in the eluate, finally concentrating, spray-drying, and pulverizing to obtain decolorized and debittered Luo Han Guo extract.

Embodiment 2

[0030] 1) Soak and decoct Luo Han Guo in water 6 times its weight to obtain water extract A;

[0031] 2) Soak and decoct Luo Han Guo in water 8 times its weight to obtain water extract B;

[0032] 3) Merge and filter A and B;

[0033] 4) The filtrate is concentrated, and the filtrate is adsorbed with D201 styrene copolymer macroporous adsorption resin for decolorization;

[0034] 5) Wash the adsorbed decolorized resin until it is colorless, then elute it with an ethanol solution with a concentration of 75-80%, and collect the eluate;

[0035] 6) Concentrate the eluate, and absorb the eluent with a column filled with MgO for deodorization;

[0036] 7) Filtrating, recovering the ethanol in the eluate, finally concentrating, spray-drying, and pulverizing to obtain decolorized and debittered Luo Han Guo extract.

Embodiment 3

[0038] 1) Soak and decoct Luo Han Guo in water 6 times its weight to obtain water extract A;

[0039] 2) Soak and decoct Luo Han Guo in water 8 times its weight to obtain water extract B;

[0040] 3) Merge and filter A and B;

[0041] 4) The filtrate is concentrated, and the filtrate is adsorbed with D301 styrene copolymer macroporous adsorption resin for decolorization;

[0042] 5) Wash the adsorbed decolorized resin until it is colorless, then elute it with an ethanol solution with a concentration of 75-80%, and collect the eluate;

[0043] 6) Concentrate the eluate, and absorb the eluent with a column filled with activated carbon for deodorization;

[0044] 7) Filtrating, recovering the ethanol in the eluate, finally concentrating, spray-drying, and pulverizing to obtain decolorized and debittered Luo Han Guo extract.

Abstract

The invention disclosed a way to prepare bleached and debitterized grosvenor momordica fruit extracts. The characteristic of the invention: adopting backstreaming to extract using water as solvent; after filtering and condensing the extracted solution, decolorizing the solution with decolorizing resin; eluting with alcohol and deodorizing the solution with deodorizing agent; reclaiming the alcohol; condensing, spray drying and pulverizing to get decolorized and deodorized grosvenor momordica fruit extracts which is white and crystalline powder with pure sweet taste and without traditional taste of Chinese traditional medicine and back bitter taster. The content of dulcoside is more than 90% (detected by ultraviolet-visible spectrophotometry), or its content is more than 60% (detected by High Performance Liquid Chromatography).
