[Function] Food materials such as ham, sausage, meat, grated meat, aquatic animals, gall, vegetable materials, and other mixed materials are water-permeable or contained in an insulating container having a pair of electrodes on both sides. Conductivity of a food material packaged with a moisture-permeable packaging material (eg, cloth, net, fibrous casing, cellulose casing, porous film, etc.) or unpackaged food material in advance so that it has substantially the same conductivity as the food material. After accommodating with the adjusted seawater, if the current is applied across the pair of electrodes, the current is evenly distributed in the food material using the seawater as the conductive liquid, and the generated Joule heat is used to quickly apply the heat to apply the current. Accurately mass-produce electric processed foods. The active ingredient contained in seawater is penetrated into the obtained electroprocessed food at the time of electroprocessing, so that the food can be finished with rich nutrition and good taste.

A manufacturing apparatus for carrying out the method,
Reference numeral 1 denotes an insulative container formed in a bottomed box shape with an open upper surface, and a pair of electrodes 4 and 5 are provided on opposing surfaces 2 and 3 of the insulative container 1, respectively. A lid (not shown) may be covered if necessary, or an insulating container that can seal the whole may be used. Then, in the insulating container 1, the food material A is stored under the flooded condition together with the seawater B adjusted by the adjusting device 9 so that the conductivity and the water temperature have predetermined proper values. The food material A is a water-permeable or moisture-permeable packaging material 6 (for example, a cloth, a ham, sausage, meat, cucumber meat, marine animals, cucumber material, vegetable material, and other mixed materials having electrical conductivity. (A net, a fibrous casing, a cellulose casing, a porous film, etc.), and the packaged food material which has been clamped at both ends to form the clamped portions 7 and 8 or an unpackaged food material. Good. The adjusting device 9 described above includes a seawater storage tank 10 for storing seawater B ′ having a conductivity of, for example, 47 mS / cm collected from the sea, as shown in FIG.
When the seawater B ′ is diluted and mixed with water and a food material A, for example, a ham having a conductivity of 28 mS / cm is subjected to electric current processing, the conductivity is adjusted to be substantially equal to the conductivity of the ham of 28 mS / cm. , The seawater storage tank 10 and the adjusting tank, which are capable of adjusting the temperature of the seawater B ′ to a temperature equivalent to the material temperature (for example, 10 ° C.) of the food material A (for example, ham) immediately before the electric current processing. 11 is connected via a supply pipe 12 with a cock.

In addition, if you use seawater with a water depth of 200 m or less, that is, deep seawater (which accounts for 95% of the total seawater volume in the world), the water temperature is stable at around 10 ° C throughout the year, as compared to the surface water of the ocean. Therefore, since the salt concentration is stable, and the number of viable bacteria is small due to the lack of sunlight, it is possible to use the seawater as sanitary water, which requires only a small amount of time to adjust the water temperature. 15 is the adjustment tank 11
