HIGHLY SOLUBLE STEVIA SWEETENER

摘要

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.

主权项

1. A method for producing a highly soluble sweetener comprising the steps of:
A) providing a Stevia sweetener powder; B) providing a solvent consisting essentially of water; C) mixing the solvent water 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.
