Polydextrose is a type of soluble dietary fiber that can be found in various food products such as baked goods, cereals, and beverages. However, there are several synonyms for polydextrose that are often used interchangeably. These include E1200, dextrans, and maltodextrins. E1200 refers to the European Union's food additive designation for polydextrose, while dextrans are a type of glucose polymer that also have similar properties to polydextrose. Maltodextrins, on the other hand, are derived from the hydrolysis of starch and are commonly used as a thickening agent or sweetener in foods. While these words may not be commonly known, they all refer to a similar ingredient used in food production.
