Lactulose liquid is light yellow, clear and sticky, and tastes sweet. Lactulose also comes in the form of white crystalline powder that is soluble in water. The relative density of lactulose powder is 1.35, and the melting point is 169℃. Its sweetness is 48% to 70% of sucrose, with a cool and refreshing flavor. With low viscosity, low calorie, high safety, good stability, it will not cause Maillard reaction. Lactulose is stable under acidic conditions and is not easily absorbed by the human body. It works mainly in the gut.
1. Food
• Sweetener: Lactulose can be used as a low-calorie sweetener for beverages, candies, dairy products, etc.
• Functional foods: Lactulose can regulate intestinal flora and is often added to functional foods, such as prebiotic drinks and prebiotic biscuits.
2. Health care products and other fields
• Prebiotics: Lactulose can improve intestinal health, strengthen immunity, and is often used in health care products.
• Foods for Special Dietary: Lactulose is used in diabetic foods and infant formula to maintain blood sugar and insulin levels.
3. Medicine
• Treatment for constipation: Lactulose is commonly used to treat chronic constipation and is suitable for adults, children and the elderly.
• Treatment for hepatic encephalopathy: Lactulose can effectively reduce blood ammonia levels, so it is usually the first choice for treatment of hepatic encephalopathy.
• Others: Lactulose can also be used to treat acute coronary syndrome, chronic renal failure, acute pancreatitis and other diseases.
1. Treatment for constipation
• Adults: 30mL/day. Maintenance dose: 10-25mL.
• Children aged 7 to 14years: 15 mL/day
Children aged 1 to 6 years: 10 mL/day
