Lactitol dihydrate

Description:

Lactitol dihydrate is a sugar alcohol, specifically a disaccharide alcohol derived from lactose. It is commonly used as a low-calorie sweetener and bulking agent in food products, particularly for those labeled as sugar-free or reduced-calorie. The chemical formula for lactitol dihydrate reflects its composition, which includes two molecules of hydrogen, one molecule of oxygen, and a specific arrangement of carbon atoms that contribute to its sweet taste. This compound is known for its mild sweetness, approximately 30-40% that of sucrose, and it has a low glycemic index, making it suitable for diabetic diets. Lactitol dihydrate is also recognized for its ability to retain moisture, which can enhance the texture of food products. In addition to its use in the food industry, lactitol dihydrate has applications in pharmaceuticals, particularly as a laxative due to its osmotic properties. It is generally regarded as safe for consumption, although excessive intake may lead to gastrointestinal discomfort in some individuals.
