D-tagatose, CAS No. 87-81-0, is a naturally occurring monosaccharide that is approximately 92% as sweet as sucrose (table sugar) but has only 38% of the calories. This makes it an attractive option for formulating low-calorie and sugar-free products. In addition, D-tagatose has a clean, sugar-like taste without the bitter aftertaste common with other low-calorie sweeteners, making it ideal for enhancing the flavor of a variety of food and beverage products.
