Abstract: The disclosure describes new forms of chip-type and other fried or baked snack-type and/or convenience food items, including sweet goods such as cookies, doughnuts, etc., which are externally coated with or which directly incorporate into their dough matrix certain starch-based compositions. Methods of using the compositions to make the food products, and the finished food products themselves are described. As external coatings, the compositions significantly increase the crispness and tensile strength of the food item after it is cooked with the coating in place, and so change the organoleptic qualities as to provide a new form of the underlying food product. On sweet goods, the coating also provides a surface barrier that stabilizes sugar icing on the outside of the product, preventing it from becoming tacky, moist, or wet, while simultaneously reducing moisture loss from the dough, adding crispness at the surface and greatly retarding staling.
