Abstract: A dried food foam product comprising: (A) about 5% to 70% by weight (dry basis) of the foam product of a flavor characterizing ingredient; (B) sufficient amounts of an undenatured proteinaceous whipping agent sufficient to provide the foam product to a density of 0.1 to 0.6 g/cc (dry weight basis) having a heat setting temperature; (C) about 0% to 55% by weight (dry basis) of the product of a nutritive carbohydrate sweetening agent; and (D) about 0.5% to 7% by weight moisture.

Abstract: High intensity microwave heating methods for heat setting food foams are provided. The methods comprise the step of subjecting a quantity of edible foams to a brief exposure to high intensity (>110 V/cm) microwave field for about 5 to 30 seconds. The high intensity microwave heating heat sets the foam to provide a stable structure. Thereafter, the heat set structures are then dried using low temperature dried to desired moisture contents ranging from about 1% to 6%. The microwave heat set foam pieces exhibit a homogeneous (i.e., without voids or irregularities) texture and a crisp, light eating quality. The edible foam products exhibit extended bowl lives and find particular suitability for use as additives to ready-to-eat cereal products. Preferred embodiments comprise high levels of fruit puree solids which by virtue of the short heat setting and low temperature drying steps exhibit high natural flavor levels.

Abstract: Microwave methods for puffing thick ready-to-eat cereal flake pieces are provided in full or partial substitution for conventional toasting and puffing methods. The methods comprise the step of subjecting a thick (>0.025 inch) cereal base piece to a brief exposure to a high intensity (>125 V/cm) microwave field for about 5 to 25 seconds. The microwave puffed cereal pieces exhibit superior puffed volume and a lighter texture compared to finished products toasted and puffed by known methods. The present methods are particularly suitable for puffing thicker flakes fabricated from whole grain, e.g., whole wheat based cooked cereal doughs.
