Polydextrose (CAS 68424-04-4) is a synthetic, randomly bonded glucose polymer that is used as a food additive . It is produced by the vacuum thermal polymerization of glucose, using sorbitol and an approved food acid as a catalyst . The resulting product is a white or off-white solid with a neutral taste, low caloric value, and excellent water solubility . It is often used as a low-calorie bulking agent in a variety of processed foods, including baked goods, confections, dairy products, and functional beverages .
Polydextrose has a reported energy value of 1 kcal/g and is not easily hydrolyzed by mammalian digestive enzymes in the small intestine . Instead, it passes intact into the colon, where it is gradually and partly fermented by the endogenous microbiota . Approximately 60% of it is excreted in the feces, contributing to its dietary fiber properties .
This food additive is recognized as a dietary fiber in more than 20 countries and has been approved for use in over 60 countries . It is considered to have similar physiological effects as other dietary fibers and has shown prebiotic potential . Polydextrose can selectively stimulate the growth and/or activity of beneficial intestinal bacteria, which is associated with several health benefits .
In the food industry, polydextrose is used for its functional properties such as providing bulk, improving texture, and enhancing the overall eating experience in low-calorie and low-sugar products . It is also used as a humectant to help maintain moisture in foods, extending their shelf life
