Biochem/physiol Actions

D-Tagatose, a ketohexose acts as a low-calorie functional sweetener. Tagatose can be used as a preservative in cosmetic, detergent and pharmaceutical formulations.[3]Tagatose is also used in diet soft drinks, chewing gum, frozen yogurt and non-fat ice cream.[4]
Potential sugar substitute rarely found in nature. Produced using a biotransformation method with L-arabinose isomerase as the biocatalyst and D-galactose as the substrate.
