Disclosed are puffed multilayered R-T-E breakfast cereal pieces and methods of preparation. In preferred embodiments, the cereal pieces have at least three cereal layers. The bulk density ranges from about 0.06 to 0.15 g/cc. The methods for fabricating the present multilayered R-T-E cereal pieces comprise: A) preparing at least three separate sheets of cooked cereal dough(s), B) layering the sheets with pressure to form a laminated sheet, C) forming individual pieces from the laminated sheet, D) drying the pieces to 9% to 13% moisture, and E) high intensity microwave puffing the pieces to form R-T-E cereals with multiple layers. The high intensity microwave field is characterized by a field strength of about 150 to 350 V/cm.

Multilayered puffed R-T-E cereal and high intensity microwave method of

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.

Dried food foam products

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 (&gt;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.

Puffed edible foams and high intensity microwave method of preparation

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 (&gt;0.025 inch) cereal base piece to a brief exposure to a high intensity (&gt;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.

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 (&gt;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.

Disclosed are methods for treating a ready-to-eat cereal base fabricated from an oat containing cereal composition to increase the stability of the product. The methods comprise the step of subjecting the cereal base to a high intensity microwave field (&gt;150 V/cm) for about 5 to 45 seconds. The treated cereal pieces exhibit superior stability and also improved flavor resulting from 'interior' toasting of the cereal base.

Microwave methods for toasting an unpuffed ready-to-eat cereal base are provided in full or partial substitution for conventional toasting methods. The methods comprise the step of subjecting a wet cereal base piece to a brief exposure to a high intensity (&gt;125 V/cm) microwave field for about 5 to 25 seconds. The microwave toasted cereal pieces exhibit superior flavor resulting from 'interior' toasting of the cereal base.

Microwave toasting of unpuffed R-T-E cereals

A method for tempering cooked cereal pellets or pieces for ready-to-eat cereals or cereal based snack half product is provided. The method involves the step of exposing the cereal pellets or pieces to a high intensity microwave field for a brief time sufficient to improve moisture distribution therein but without causing the pellets or pieces to puff. A high intensity microwave field has a field strength of &gt;90 V/cm in free space. Exposure times range from about 15 to 30 seconds depending upon the initial temperature and moisture content of the pellets. The microwave tempered cereal pellets or cereal based snack half products can thereafter be conventionally processed to form finished cereal products. The finished cereal products exhibit superior physical and organoleptic attributes such as volume, improved texture, uniformity and for R-T-E cereal embodiments, also longer bowl life.
