Polydextrose
Polydextrose is an artificially synthesized polysaccharide made primarily from glucose, with a small amount of sorbitol and citric acid, through high-temperature polymerization. Polydextrose is recognized by the World Health Organization and the Food and Agriculture Organization of the United Nations as a type of total dietary fiber.
As a dietary fiber, polydextrose is not a 'sugar' or 'carbohydrate' in the traditional sense. The human body lacks enzymes to break down polydextrose, so most of it passes through the gastrointestinal tract intact and is eventually excreted. Polydextrose appears as white or off-white solid granules and is easily soluble in water.
Why is polydextrose favored by the food industry?
- It can replace sugar and fat to provide good volume and texture, while not compromising the overall flavor of the food, and is therefore often used in developing low-sugar, low-fat, and low-calorie healthy foods.
- On food ingredient lists, polydextrose often serves multiple roles such as a thickener, stabilizer, moisture retention agent, and leavening agent.
- Adding polydextrose to food can increase the dietary fiber content of the final product, meeting consumers' health needs.
- Polydextrose can help low-calorie foods maintain a good texture. For example, in frozen desserts, it can lower the freezing point, making the texture smoother.

Is polydextrose safe?
The safety of polydextrose has been widely recognized by official authorities. In China, it complies with national food safety standards; in the European Union, its food additive number is E1200; in the United States, it is approved by the FDA for use in various foods.
For most people, consuming it in recommended amounts is safe. However, excessive intake may cause temporary gastrointestinal discomfort such as bloating and gas. If you want to effectively supplement dietary fiber without changing your existing eating habits, foods fortified with polydextrose are a very convenient option.
