Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention constantly applies a uniform electric current to a food material contained in a shape-retaining container through a conductive liquid even if the food material is in excess or in shortage. The present invention relates to a method for producing an electrically processed food, which can be subjected to heat sterilization treatment for food materials by rapid heating and mass production thereof.

[0002]

2. Description of the Related Art Conventionally, a food product is filled in a package having current-carrying parts at both ends to form a packaged product,
After containing the shape-retaining frame in an insulating container having a pair of electrode plates inside, the shape-retaining frame is housed together with a conductive liquid in the shape-retaining frame having a current-carrying port facing the current-carrying part at both ends. As described in Japanese Patent Publication No. 2-24513, the applicant of the present invention has previously developed and known a method for producing an electrically processed packaged food in which a food material is sterilized by heat treatment.

[0003]

By the way, in the conventional method for producing an electrically processed packaged food of this kind, the maturing heat sterilization of the food material is carried out by the action of electricity passing through the conducting liquid and the conducting port and the conducting portion. Therefore, the current is cut off by the remaining wall surface in the portion other than the current-carrying port, and the current cannot be conducted.

Therefore, when the opening area of the current-carrying port is small, a large amount of electric current cannot be applied to the food material. However, since a uniform energizing effect cannot be applied, it is not possible to manufacture a uniform energized processed food product.

Therefore, as one means for solving this, when a large number of relatively large current-carrying ports are formed at both ends of the shape-retaining frame, the strength of both ends of the shape-retaining frame is remarkably reduced and weakened. Permitting that both ends may be damaged during handling, or if the amount of food material stored in the shape retention frame is not uniform, for example, store a small package relative to the capacity of the shape retention frame and conduct electricity treatment. When you try to create a void inside,
As a result, there is a problem in that it is not possible to obtain a packaged product having a predetermined shape-retaining shape.

The present invention is directed to the food material, even if it is unwrapped.
Alternatively, even if there is an excess or deficiency in the amount to be energized, the food material and the electrode body can be surely brought into close contact with each other by simply moving and fixing the pair of electrode bodies opposite to each other on both sides of the shape-retaining container, and the conductive liquid is used. It is possible to produce an electrically processed food that has been heat-sterilized into a predetermined shape by the applied electricity effect, or even if it does not have an electricity port, a large amount of current can be uniformly applied to the food material. It is an object of the present invention to provide a method for producing an electrically processed food which is capable of mass-producing a homogeneous electrically processed food in a short time.

[0007]

In order to achieve the above object, in the method for producing an electrically processed food of the present invention, the first method is used.
The method described in paragraph (1) above is used for a packaged or unpackaged food material that is made of an insulating material and is housed in a shape-retaining container that has a pair of electrodes on both sides. After being stored together with the conductive liquid in the above, the food material is subjected to heat sterilization treatment by applying an electric current to the food material through the conductive liquid.

In the method according to the second aspect of the present invention, the pair of electrode bodies can be moved and fixed in the shape-retaining container.

[0009]

When manufacturing an electrically processed food by the method for manufacturing an electrically processed food shown in FIGS. 1 to 3, first, a food product is filled into a package and plasticized, or an unpackaged state. Remove the lid, and store the food material in a shape-retaining container with a pair of electrode bodies inserted and fixed at both ends.
After the packaging body or the unwrapped food material and the pair of electrode plates are brought into close contact with each other, the lid body is covered.

Next, after the shape-retaining container is housed in an insulative container having a pair of electrodes in a submerged state together with a conductive liquid, current is supplied to the conductive liquid by energizing the pair of electrodes. Through the entire surface of both electrode bodies of the shape-retaining container that is close to both electrodes through the food material, the food material is smoothly circulated through the food material, and the food material is heated and sterilized uniformly in a short time.

In addition, when a large amount of food material is contained in the shape-retaining container, one or both electrode bodies are moved away from each other, or when they are small, they are moved and fixed so as to approach each other. The pair of electrode bodies are always in close contact with each other, and a predetermined amount of shape-retaining food material according to the amount accommodated in the shape-retaining container can be accurately heat-sterilized.
