Polydextrose is a soluble fiber commonly used as a low-calorie bulking agent in food products. It is made by combining glucose with sorbitol and citric acid, which undergoes polymerization to form a chain of glucose molecules with sorbitol and citric acid branching off. The result is a white, odorless powder that is low in calories and has a slightly sweet taste. In addition to being low in calories, polydextrose has other health benefits. It is a prebiotic fiber, which means it promotes the growth of healthy bacteria in the gut.
This can improve digestion, boost the immune system, and reduce the risk of certain diseases such as colon cancer. Polydextrose is also low on the glycemic index, which means it does not cause a significant rise in blood sugar levels. Polydextrose is commonly used in food products such as baked goods, candies, frozen desserts, beverages, and dairy products. It is often used as a sugar substitute or to replace some of the fat in a product to reduce its calorie content. It is also a popular ingredient in many low-carbohydrate and low-sugar diets.
This property makes it useful in low-calorie food products, where it can replace sugar and fat. Polydextrose has several health benefits that make it an attractive ingredient for food manufacturers and consumers. It is a soluble fiber that can help to promote digestive health by increasing the bulk of stool and reducing the risk of constipation. It can also help to lower cholesterol levels by binding to bile acids in the intestines and promoting their excretion. This property makes it useful in products that are marketed as heart-healthy.
