Oat flour is an ideal ingredient when you’re looking to add flavor, nutrition, and viscosity to a wide range of end products. Oat flour can be used as a multi grain flour, preservative for ice cream and other dairy products, as a thickener for soups, gravies, and stews, and to add nutrition to breads, muffins, crackers, beverages and desserts.
