Stevia extract production: a clean 2-step process

At Stevia Natura, we extract and purify in particular Rebaudioside A which is the main steviol glycoside contained in stevia leaves

Steviol glycosides are water-soluble molecules.

Extraction is done by infusion in hot water followed by elimination of impurities. This process increases the concentration of steviol glycosides by up to 90%: this is “crude”.

The purification step consists of obtaining a high purity stevia leaf extract from the crude, with 2 objectives:
  • comply with EU regulations (min. 95% purity)
  • give a sweeter taste
