8 is an insulating container, 8 is a pressing body, and 9 is an electrode body.

Problems to be Solved by the Invention Incidentally, in conventional hermetically packaged foods of this type, food materials filled in an insulating packaging bag were always contained in order to allow current to flow uniformly through the filled food materials. Since it is in close contact with the salt water contact body, the packaged food obtained by the aging heat treatment by energization is bitten into the salt water contact body and firmly adhered thereto.

Therefore, when you open the insulating packaging bag to serve the packaged food and try to peel off the salty water contacts attached to both sides of the packaged food, the salty water contacts stick tightly to the packaged food and become loose. As a result of not being able to peel off, a part of the packaged food is sometimes peeled off while remaining attached to the salt-containing water contact body, resulting in the problem that the surface becomes jagged and the product value is significantly reduced.

Means for Solving the Problems The present invention solves the above-mentioned problems, and the details thereof will be explained below with reference to FIGS. 1 to 5, which correspond to embodiments.

A pair of current-carrying plates 102 configured as described above is formed by covering only the moisture-containing current contacting body 111 stuck to the inner surface of the current-carrying plate 102 with a moisture-permeable film 105. , 102 are inserted into the left and right opening edges 101a, 101b of the insulating packaging bag 101 in the same manner as in the first invention, and then the sealed package B is obtained by tightening with the fasteners 106, 106. It is something that can be done.

Effects of the Invention In short, since the present invention has the above-described configuration, the raw food material A sealed and stored in the insulating packaging bag 101 is covered with a moisture-permeable film body 1G5, 105 having high moisture permeability. Through the current-carrying plates 102, 102 or moist electrical connection bodies 111, 1
11, the moisture permeable membrane 105.105 is made of raw food material A.
It quickly permeates the water contained therein or the dilute salt water moistened in the moist electrical contact 111.111 and becomes a wet feather state, making it a conductor with good current flow, thereby ensuring uniform distribution. Due to the energization action, the raw food material A can be sterilized by ripening in a short time to provide a sweet-tasting sealed packaged food, and the sealed packaged food is sealed in an insulating packaging bag 101. Not only can it be stored for a long period of time in the same state, but also when the current-carrying plates 102, 102 are to be peeled off, a part of the processed food can be added to the current-carrying plates 102, 102 or the moist electrically conductive bodies 111, 111. The moisture-permeable film body 105 can be easily peeled off by the peeling action of the moisture-permeable film 105 without adhesion, and a packaged food with a smooth surface and high commercial value can be provided at any time.
