Abstract
D-tagatose is manufactured from cheese whey and/or milk. The cheese whey and/or milk is hydrolyzed to prepare a mixture comprising galactose and glucose. Galactose is separated from the glucose by fermentation and subjected to isomerization using L-arabinose isomerase, thereby producing D-tagatose. The D-tagatose can be used as a reduced calorie food sweetening and bulking agent, as an intermediate for the synthesis of optically active compounds, and as an additive in detergent, cosmetic and pharmaceutical formulations.
