What it is

Tagatose is a low-calorie sweetener that occurs naturally in small amounts in some dairy products. It is manufactured from lactose, a sugar found in milk, through a process of isomerization.

Why it's used

Tagatose is used as a sugar substitute in a variety of foods, including baked goods, dairy products, and beverages. It provides sweetness with fewer calories than regular sugar and can also enhance flavor.

Health notes

Tagatose is generally recognized as safe (GRAS) by the FDA for use as a sweetener. Studies suggest it may have a prebiotic effect, feeding beneficial gut bacteria. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated tagatose and established an acceptable daily intake. Some individuals may experience digestive discomfort, such as gas or bloating, when consuming large amounts.

Allergen info

Tagatose is derived from lactose, which comes from milk. Therefore, it is considered a dairy-derived ingredient and is not a major allergen on its own. It does not contain gluten.
