Abstract
Tagatose is manufactured by hydrolyzing lactose to galactose and glucose and isomerizing galactose to tagatose and chromatographic separation and recycling any unconverted compounds. Thereby high yields of pure tagatose are obtained.
Claims18
A process for manufacturing of tagatose comprising
- a) hydrolyzing lactose or a lactose containing starting material with a lactase to obtain galactose and glucose
- b) isomerizing the obtained galactose in the presence of glucose with a L-arabinose isomerase to obtain tagatose, and
- c) separating by chromatography products and unconverted compounds and recycling of unconverted compounds to the process.
