They are said to be the industry's first commercially viable stevia patents.
PureCircle (Oak Brook, IL), a leader in the production of stevia (Stevia rebaudiana) extracts, has been awarded three patents for the natural sweetener from the U.S. Patent and Trademark Office.
The company says its patents are an industry first in “commercially viable, high purity stevia patents.”
“Specifically, the technologies in these patents establish the process that can be used for manufacturing high purity steviol glycoside extract (SG95) and different components, such as Reb A and Stevioside, that could not be achieved with earlier technology on a commercial scale,” said the company in a recent press release. “As part of these patents, the processes and methods for developing PureCircle’s highly consistent products such as Reb A 97, SG95, and enzyme treated stevia products are covered, including their usage across the entire breadth of product categories, from food and beverage to cosmetics.”
