ABSTRACT:
A method is provided for bonding together the layers of a laminated food product, such as farinaceous dough layers. The methods comprise applying ultrasonic energy (12 kPa-25 kHz, 1,000 to 4,000 watts) to form acoustically created bonds between the food layers. The method is particularly suitable for use preparing multilayered R-T-E cereal pieces, especially those that are center filled, exhibiting greater seam integrity and reduced leakage of the center filling. The resultant food product has two layers with an acoustic bond between the layers.
