Abstract: The present disclosure relates to a method and system for the preservation and regeneration of pre-baked bread. The method comprises a preservation phase including the steps of enclosing the pre-baked bread in a receptacle capable of withstanding high temperatures, and hermetically enclosing the receptacle in an atmosphere conducive to the preservation of the pre-baked bread. The method may further include the step of heating the receptacle containing the pre-baked bread. The system comprises a packaging for preservation of pre-baked bread, including a receptacle for containing the pre-baked bread, the receptacle being capable of withstanding high temperatures. The packaging also comprises an enclosure for hermetically enclosing the receptacle, the enclosure containing a gas conducive to the preservation of pre-baked bread, such as CO2. The system may also include an oven configured to heat the receptacle and pre-baked bread at a temperature between about 100 degrees and 250 degrees Celsius.

Abstract: A bag with a tube-shaped body is made of a flexible material, sealed to from the bottom and opening at the top. It also has a separate sealing device in order to close the opening for the purposes of storage and transport. On the tube-shaped body there are at least two parallel pre-cut lines on the front and back or printed markings that run from the opening of the bag to the bottom and that lead to two lateral strips that are designed to be tied into a knot and thereby shut the opening of the bag once it has been opened without the need for separate sealing devices.
