Abstract: A flexible paper microwave package in the form of an easily expandable, nontrapping bag (18) is disclosed including a bottom wall (20) and a top wall (22) interconnected together adjacent their circular outer peripheries (20a, 22a) by first and second interconnection portions (26a, 26b). In one preferred form, the top wall (22) is formed from a first portion (22d) having a generally oval shaped access opening closed by a generally oval shaped closure portion (22e) interconnected by a wet adhesive seal (40) to the first portion (22d). In a preferred form, the wet adhesive seal (40) is formed by a plurality of spaced, parallel bands (400, 401, 402) defining a plurality of spaced, parallel spaces therebetween for resisting any leakage from the interior of the bag (18) through the seal (40). The bottom and top walls (20, 22) expand into an opposing double domed shape as the food product is being popped, puffed, or expanded in the microwave oven.

Abstract: The invention is a packaging system for refrigerated leavened dough or batter compositions and includes a method for determining package seal strength for a refrigerated leavened composition. The system provides an environment within the package such that the composition attains a desired specific volume upon baking or cooking. The method includes the process of determining the specific volume required for the refrigerated leavened composition after baking, determining internal equilibrium pressure required to attain the specific volume after baking, determining the package dimension subject to the internal equilibrium pressure, and defining the pressure holding capacity required to maintain this pressure during the storage life of the refrigerated composition.

Abstract: A dough product suitable for storage by refrigeration or freezing that includes a package constructed as a chub from a substantially gas impermeable material closed at opposite ends around a dough portion containing at least flour, a liquid, and a leavening system. The package includes at least one gas transfer passage. The leavening system at least partially proofs the dough after insertion into and closing of the package, such that the dough expands to a volume substantially equal to the volume of the package and has a high raw specific volume. The proofed dough bears against and seals the gas transfer passage to thereby arrest further proofing and prevent oxygen entry into the package. The dough product is then stored at refrigeration or freezing temperatures for later baking, without additional proofing, into a bread product having a high baked specific volume.

Abstract: The present invention includes a gas flushing device that includes a piston portion having a hole to introduce the flushing gas. The present invention also includes a method for removing air from a container that stores food. The method includes providing the gas flushing device and aligning the device with the container. The method also includes moving the piston of the device into the container until the piston encounters a predetermined pressure. Next, the piston is retracted from the container while simultaneously releasing a fushing gas through the hole. Next, the piston is removed from the container and the container is sealed in an inert atmosphere.

Abstract: A refrigerated dough system is provided which includes a dough in a container flushed with a gas. The dough contains a leavening agent capable of generating gas in the dough after the dough is sealed in the container. The container is provided with a pressure release mechanism to release excess pressure generated within the container as the dough leavens and during storage. The dough system is capable of sustaining a leavened dough structure during storage so that upon baking the dough, the resulting baked product resembles a freshly prepared and baked dough.
