High raw specific volume dough in a chub

A packaged dough product suitable for storage by refrigeration or freezing comprising:

• a chub package constructed from a substantially oxygen and carbon dioxide gas impermeable material that is relatively flexible but is relatively non-elastic and non-expandable, the package having an interior volume and the package including at least one gas transfer passage through a substantially closed, crimped clip end of said chub package;
• and
• a dough portion in a non-proofed state disposed inside the chub package, spaced from said passage, the dough portion containing at least flour, liquid and a leavening system, the dough portion having a volume smaller than the interior volume of the package;
• said passage being sufficient to allow gas flows out of the package through the passage during proofing of the dough portion in the package, yet small enough to prevent any of the dough portion from flowing out of the package;
• said dough portion and said leavening system being present in the package in an amount sufficient such that the dough portion will undergo proofing in the package and expand to cause the dough portion to expel air from the package and cause the dough portion to completely fill the volume of the chub package and substantially seal the gas passage to prevent entry of oxygen and to produce a positive pressure in the package and provide the dough portion in a proofed state.
