Example Embodiment

[0012] Example I In the first step, 200g of mogroside extract containing 80% mogroside was dissolved in 3000ml of water to obtain a mogroside solution, which tasted a little bitter. In the second step, the above solution was passed through a water-balanced anion exchange resin column. The exchange column is 200ml and contains 100g of Amberlite-IRA410 resin. The Luo Han Guo solution is eluted from the resin, and the acidic bitter substances are bound to the resin to obtain about 2950ml of eluate. Most of the bitterness has been removed, and almost no Bitter Momordica grosvenori extract; In the third step, the Momordica grosvenori solution obtained by the above treatment is passed through the water-balanced cation exchange resin Amberlite-IR120+ to remove all basic bitter substances. The Momordica grosvenori extract obtained by the two-step treatment There is no bitter taste at all; in the fourth step, the Luo Han Guo extract solution is spray-dried to obtain 190 g of Luo Han Guo ex...

Example Embodiment

[0013] Example II In the first step, 10g of mogroside extract containing 80% mogroside was dissolved in 150ml of water to obtain a mogroside solution, which tasted a little bitter; in the second step, the above solution was passed through a water-balanced mixed ion exchange resin column Qualichem MB108P 10ml, Momordica grosvenori solution is eluted from the resin, and the acidic and basic bitter substances are bound to the resin to obtain about 145ml of eluate. All the bitterness has been removed, and a Momordica grosvenori extract without bitterness is obtained; In three steps, the Luo Han Guo extract solution was spray-dried to obtain 9.6 g of Luo Han Guo extract powder, with a yield of 96%.

Example Embodiment

[0014] Example III In the first step, 1g of mogroside extract containing 80% mogroside is dissolved in 15ml of water to obtain a mogroside solution, which tastes a little bitter; in the second step, the above solution is passed through a water-balanced anion exchange membrane Pall's SB -6407 (diameter 47mm), the Momordica grosvenori solution is eluted from the membrane, and the acidic bitter substances are bound to the membrane to obtain approximately 14.5ml of eluate, most of the bitterness has been removed, and the extraction of Momordica grosvenori with almost no bitterness is obtained The third step, the Momordica grosvenori solution obtained by the above treatment is then passed through the water-balanced cation ion exchange membrane Pall’s ICE450 (diameter 47mm) to remove all alkaline bitter substances, and the above two steps are processed to obtain The momordica grosvenori extract is completely free of bitter taste; in the fourth step, the solution of the momordica grosven...
