Abstract: Chewing gum compositions are described that include one or more stereoisomers of monatin, a naturally occurring high-intensity sweetener.

Abstract: The present invention relates to novel sweetener compositions comprising monatin and methods for making such compositions. The present invention also relates to sweetener compositions comprising specific monatin stereoisomers, specific blends of monatin stereoisomers, and/or monatin produced via a biosynthetic pathway in vivo (e.g., inside cells) or in vitro.

Abstract: The present invention relates to novel beverage compositions comprising monatin and methods for making such compositions. The present invention also relates to beverage compositions comprising specific monatin stereoisomers, specific blends of monatin stereoisomers, and/or monatin produced via a biosynthetic pathway in vivo (e.g., inside cells) or in vitro.
