Abstract

Abstract Methods for toasting a puffed ready-to-eat cereal base are provided to increase the toasted flavor thereof. The methods comprise the step of subjecting the cereal base to a brief exposure to a high intensity (>125 V/cm) microwave field for about 5 to 45 seconds. The microwave toasted cereal pieces exhibit superior flavor resulting from "interior" toasting of the cereal base.
