Examples
Embodiment 1
[0051] Preparation of isosteviol: 0.6% stevioside aqueous solution, add sulfuric acid to make the concentration 4% (W / W), mix well, heat at reflux for 20 minutes, filter the white precipitate, and dry to get crude isosteviol (content is about 40%), isosteviol can also be purified by column chromatography.
[0052] Preparation of β-cyclodextrin supramolecularization composition of isosteviol: Mix 500 grams of β-cyclodextrin with 2500 ml of pure water, keep warm at 60°C and stir to form a solution, add 150 grams of isosteviol, keep stirring for more than 12 hours , cooled slowly, left overnight, filtered, and vacuum-dried to obtain a white clathrate, which contained 1.3% isosteviol in the solid.
Embodiment 2
[0054] Mix 100g of β-cyclodextrin with 300ml of pure water at room temperature, stir to make a suspension, add 20g of solid isosteviol (content 70%-95%), mix well, and grind (about 5-8 hours) , cooled, filtered, and dried at 40°C to obtain a white clathrate.
Embodiment 3
[0056] Weigh 5 grams of β-cyclodextrin and add 30 milliliters of water to make a suspension, add one-fifth of its mass (ie 1 gram) isosteviol powder, mix, and grind for 2 hours at 25°C to form a paste. Cool, filter, and dry at 60°C until it becomes powdery to obtain a white clathrate.
