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.
