Application

D-(-)-Tagatose has been used as a carbohydrates for fermentation. It has also been used as one of the standards to confirm the identity of majority of the metabolites selected by least absolute shrinkage and selection operator (LASSO).

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.Tagatose is also used in diet soft drinks, chewing gum, frozen yogurt and non-fat ice cream.
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.

The continuous enzymatic conversion of D-galactose to D-tagatose with an immobilized thermostable L-arabinose isomerase in packed-bed reactor and a novel method for D-tagatose purification were studied. L-arabinose isomerase from Thermoanaerobacter mathranii (TMAI) was recombinantly overexpressed and immobilized in calcium alginate.
