Tagatose


Tagatose is a monosaccharide form of sugar that is approximately 92% as sweet as sucrose, or table sugar. It is naturally occurring and can be found in a variety of fruits and dairy products. Tagatose is often used as a low-calorie sweetener and prebiotic dietary fiber in food and beverage products.

Chemical Structure[edit | edit source]

Tagatose has the chemical formula C6H12O6, the same as glucose, but its structure differs in the arrangement of the hydroxyl groups. It is a ketohexose, a type of monosaccharide with a ketone functional group and six carbon atoms.

Health Benefits[edit | edit source]

Tagatose has several potential health benefits. It has a low glycemic index, which means it does not cause a rapid rise in blood sugar levels. This makes it a suitable sweetener for people with diabetes. It also acts as a prebiotic, promoting the growth of beneficial gut bacteria. Some studies suggest that tagatose may help reduce body weight and fat mass, although more research is needed in this area.

Production[edit | edit source]

Tagatose is produced from lactose, a disaccharide found in milk. The lactose is first hydrolyzed to glucose and galactose, and the galactose is then isomerized to tagatose using an enzyme called l-arabinose isomerase.

Uses[edit | edit source]

Tagatose is used in a variety of food and beverage products, including baked goods, chocolates, and soft drinks. It provides a similar taste and texture to sucrose, but with fewer calories. It is also used in pharmaceutical products due to its prebiotic properties.

Safety[edit | edit source]

Tagatose is generally recognized as safe (GRAS) by the Food and Drug Administration (FDA). However, like other sugar alcohols, it can cause digestive issues if consumed in large amounts.
