Abstract
A method of making a natural sweetener based on Stevia rebaudiana includes extraction of plant parts of Stevia rebaudiana with a solvent to provide an extract, and subjecting the extract to an extraction with a supercritical gas to obtain an extraction residue which is freed from undesired and taste-impairing constituents.
Claims18
A method of making a natural sweetener substantially free of bitter aftertaste from an extract obtained from plant parts of Stevia rebaudiana;
- comprising the step of extracting said extract with a supercritical gas to obtain an extraction residue.
A method of making a natural sweetener from Stevia rebaudiana;
- comprising the steps of:
- providing as starting material plant parts of Stevia rebaudiana;
- extracting the plant parts with a solvent to provide an extract;
- and
- subjecting the extract to an extraction with a supercritical gas to obtain an extraction residue.
A method of making a natural sweetener from Stevia rebaudiana;
- comprising the steps of:
- introducing as starting material plant parts of Stevia rebaudiana in an extraction vessel;
- and
- separating from the plant parts an extract by feeding a supercritical gas into the extraction vessel so as to obtain an extraction residue.
A method of making a natural sweetener from an extract obtained form plant parts of Stevia rebaudiana;
- comprising the step of extracting the extract with liquid carbon dioxide to obtain an extraction residue.
A method of making a natural sweetener substantially free of bitter aftertaste, from .alpha.-glycosylated stevioside or rebaudiside A, comprising the step of extracting said .alpha.-glycosylated stevioside or rebaudiside A with a super-critical gas to obtain an extraction residue.
