Abstract
A method for making a highly soluble Stevia sweetener is described. The resulting sweetener readily provides solutions with up to or greater than 30% concentration which are stable for more than 24 hours.
Claims6
A method for producing a highly soluble sweetener consisting of the steps of:
- A) providing a Stevia sweetener powder;
- B) providing a solvent consisting essentially of water;
- C) mixing the solvent and Stevia sweetener powder to make a mixture;
- D) increasing the temperature of the mixture by a gradient heat treatment method having a rate of temperature change of about 1° C. per minute to an elevated temperature of about 110-140° C. to make a solution;
- E) holding the solution at the elevated temperature;
- F) decreasing the temperature of the solution by a gradient cooling method having a regular rate of temperature change to obtain a stable Stevia sweetener solution having a clear solution stability without visible crystallization or cloudiness at 25° C. for 24 hours;
- and
- G) optionally spray drying the stable Stevia sweetener solution, to provide an amorphous highly soluble powder of Stevia sweetener having a solubility of at least about 5 grams per 100 grams of water.
