“Highest Purity” Stevia Extract Now Patented in Canada

March 6, 2014

SGF will now sell its Puresse Stevia 100 and Altesse Stevia 99 branded sweeteners in Canada under this new patent.

A new patent means that Sweet Green Fields (SGF; Bellingham, WA) is now the only company that can sell Rebaudioside A stevia extract at a 98.6% or higher purity in the Canadian market. The patent covers this threshold, regardless of manufacturing technique. The company will now sell its Puresse Stevia 100 and Altesse Stevia 99 branded sweeteners in Canada under the patent.

The exact Reb A purity specifications for Altesse 99 and Puresse 100 are≥ 99% and ≥ 99.6%, respectively.

What about in the U.S. market? Mel Jackson, PhD, SGF’s vice president of science, tells Nutritional Outlook that the company has also filed a similar patent in the United States. Jackson says the company is currently unaware of any U.S. product patents covering Reb A at this purity level.

“Sweet Green Fields achieved another industry first, as no other patents cover Reb A purity higher than 98.7%,” said Mike Quin, senior vice president of sales and marketing, in a press release.

The company says it uses numerous methods to remove impurities.

Puresse Stevia 100 is also currently covered by patents in Australia and New Zealand, with patents pending in five additional countries worldwide, including the U.S. and Europe.
