Arrowroot powder is the purified native starch extracted from the rhizomes of Maranta arundinacea (a tropical tuber). It is a gluten-free, neutral-tasting thickener widely used in cooking and food manufacturing to provide viscosity and clear gels. Nutritionally, it is composed almost entirely of digestible carbohydrate (starch) and provides energy but minimal protein, fat, fiber, or micronutrients. As a traditional food starch, it is generally regarded as safe when used in foods.
