What it is
Maltodextrin is a polysaccharide, a type of carbohydrate, made from starch. It is typically produced from corn, rice, potato starch, or wheat. The starch is broken down into smaller chains of glucose molecules through a process called hydrolysis.
Why it's used
Manufacturers use maltodextrin as a thickener, a bulking agent, or a flavor enhancer. It can also be used as a sweetener, though it is less sweet than table sugar. You can find it in a wide variety of processed foods, including baked goods, sauces, soups, and processed meats.
Health notes
In the U.S., maltodextrin is generally recognized as safe (GRAS) by the FDA. It is a carbohydrate and will affect blood sugar levels. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated maltodextrin and established an acceptable daily intake. Evidence on its effects on gut microbiota is mixed, with some studies suggesting potential impacts while others show none.
Allergen info
Maltodextrin is not one of the nine major allergens. If derived from wheat, it may contain gluten, but processing often removes gluten.
