“Since Reb D has improved taste compared with Reb A, it commonly delivers a cleaner taste when combined with other sweeteners and non-sweeteners,” says Francis. “We are currently using Reb D to remove the bitterness/after-taste found in other steviol glycosides.”

The new patent was issued by the United States Patent and Trademark Office (USPTO). SGF says it now has patent rights in the United States, Canada, Mexico, China, New Zealand, Australia, and 32 European countries.
