Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention is directed to a diluted salt solution containing a large number of salted raw food materials stored in an insulating container in a stacked manner in an insulating container. The present invention relates to a method for producing an energized processed food, which can be sterilized by heat sterilization within a short period of time by placing the energized food in a pickled state and then being energized to produce an energized processed food with good taste.

[Prior Art] Conventionally, when manufacturing packaged foods by subjecting raw materials such as raw seafood, livestock animals, or grains that can be obtained at low cost to heat sterilization, the ends of an insulating shape-retaining cylinder of a predetermined shape are generally used. In the open part, a shape-retaining frame for current-carrying, which has a large number of current-carrying holes in the flat part, is slidably fitted facing each other, and a planar salt-containing water is placed on both the inside and outside of each of the shape-retaining frames for current-carrying. After filling and storing the materials one by one in a packaging container constructed by pasting the electrical conductor, a pair of electrode plates is pressed from both sides so that they come into close contact with the salt-containing water electrical conductor, and current is applied between the pair of electrode plates. A packaged food manufacturing method capable of obtaining a packaged food by applying the above method is well known and was described in, for example, Japanese Patent Application Laid-Open No. 56-5042 before the present application.

[Problem to be solved by the invention] However, according to the above-mentioned known manufacturing method,
During its production, there is a filling process in which raw food materials are filled into insulating shape-retaining cylinders one by one, and an open part after filling with the material is closed with a current-carrying shape-retaining frame to which a salt-containing water conductor is attached. Also, during energization processing, a process such as bringing a pair of electrode plates into close contact with the salt-containing water contact body is required, and the shape of the material is limited to that of the insulating shape-retaining frame, and there are many materials with arbitrary shapes. It is not possible to simultaneously heat sterilize the product without packaging it, and as a result, mass production cannot be achieved through a simple manufacturing process. When both the electrically connected body and the pair of electrode plates are not in close contact with each other, there are problems such as a half-baked product due to poor energization.

The present invention involves the filling operation in which raw food materials are filled into insulating shape-retaining cylinders one by one, and the opening after filling with raw food materials is closed with a current-carrying shape-retaining frame to which a salt-containing water conductor is attached. In the case of work and energization processing, it is possible to simply energize a surrounding wall of a large number of raw food materials of any shape that have been salt-treated, without having to place a pair of electrode plates in close contact with a salt-containing water electrical contact. After storing the raw food materials in a stacked manner in an insulating storage basket provided with a window, the insulating storage baskets are stored in an insulating container with dilute salt having a salt concentration lower than that of the raw food material. By submerging the liquid in a submerged state and energizing it, the current can be uniformly passed through the raw food material with a high salt concentration using the dilute salt solution as the energizing medium, resulting in less power consumption. A method for manufacturing electrified processed foods that can sterilize a large number of food materials at once in a short time with simple operations, and mass-produce electrified processed foods of any shape that are inexpensive and have good taste. is intended to provide.

[Means for Solving the Problems] Therefore, the technical problem of the present invention is to sterilize a large number of raw food materials of arbitrary shapes at one time and evenly through a simple manufacturing process, thereby making them taste good. The aim is to mass produce electrically processed foods.

In order to achieve the above object, the method for producing energized processed foods of the present invention involves stacking raw food materials containing salt evenly in an insulating container having a large number of energizing windows on the surrounding wall. The insulating storage basket is housed in an insulating container, and is submerged in a dilute salt solution with a salt concentration lower than that of the raw food material, and is heated by energization. The material is sterilized by heat sterilization.

[Function] An insulating storage basket 1 having a large number of raw food materials A having an arbitrary shape and evenly containing an appropriate amount of salt for good energization, and a peripheral wall 2 provided with a large number of energization windows 3. They are stored in a stacked manner. In this way, when a large number of raw food materials A are stored in the insulating storage basket 1, the insulating storage basket 1 is
It is stored in an insulating container 7, and is submerged in a dilute salt solution B having a salt concentration lower than that of the raw food material A. Then, the raw food material A having an arbitrary shape will be in a state of being soaked in the diluted salt solution B.

Therefore, if current is applied between the pair of electrode plates 9, 9, the current will flow smoothly and uniformly through the raw food material A through the numerous current-carrying windows 3, using the dilute salt solution B as the current-carrying medium. Then, a large number of raw food materials A are sterilized at once in a short period of time using the generated Joule heat,
Electrically processed foods with good taste can be obtained. Then, once the energized processed food is obtained by the above operation,
It is sufficient to pull it out from the insulating container 7 and then take it out from the insulating storage basket 1.

[Example] Next, an apparatus for carrying out the method of the present invention will be described based on an example shown in the accompanying drawings.

In FIG. 1, A is raw aquatic animals that can be obtained at low cost, such as sardines, horse mackerel, saury, mackerel, and other fish, or raw fish meat materials, or raw livestock animals, such as cows, Meat such as pigs and chickens,
or a raw food material of any shape made of these paste materials or mixed materials thereof,
The raw food material A has a salt concentration of, for example, 2% to 3%.
% evenly.

Note that suitable seasonings or spices may be added to the raw food material A as required.

The reason for adding 2% to 3% salt to the raw food material A as described above is to allow the current to flow uniformly through the raw food material A during the subsequent electrical processing, and at the same time to The object of the present invention is to improve the taste and maintain the quality of food material A.

Reference numeral 1 denotes an insulating storage basket which is formed into a bottomed cylindrical shape with an open top surface and has a large number of current-carrying windows 3 opened in the peripheral wall 2. is covered with an insulating lid 4 which is pivotally connected at one end by a hinge 5 so as to be openable and closable.

Therefore, a large number of raw food materials A having arbitrary shapes can be accommodated in the insulating container 1 in any desired condition by opening the insulating lid 4. 6
is a handle provided on the insulating lid 4.

B is a dilute salt solution with a salt concentration lower than that contained in the raw food material A, for example, 0.25% or less, and the dilute salt solution B has an appropriate shape and is stored in an appropriate amount in an insulating container 7. be done.

The above-mentioned insulating container 7 is formed in the shape of a bottomed case with an open top surface, and a pair of electrode plates are inserted into and inserted into the opposing walls 8, 8 side of the insulating container 7 so as to be freely inserted and removed. 9, 9 are arranged, and the insulating storage basket 1 containing a large number of raw food materials A containing salt with a high salt concentration is stored submerged in the dilute salt solution B. After that, when electricity is applied between the pair of electrode plates 9, 9, the current flows smoothly and uniformly through the raw food material A using the diluted salt solution as the energizing medium, and the generated Joule heat, for example, 95°C, is quickly applied. Raw food material A can be subjected to heat sterilization treatment at one time to produce an electrically processed food with good taste. During the above-mentioned electrification process, a large number of raw food materials A having arbitrary shapes are simply placed in the insulating storage basket 1 and soaked in dilute salt solution B to form an insulating material. By simply inserting the raw food materials A into the container 7, a large number of raw food materials A can be energized at once. The operation and equipment are simple, as the work of filling the shape-retaining cylinder with the open sides of the shape-retaining tube and closing it with the energizing shape-retaining frame, as well as the energizing work of pressing the electrode plate against the energizing shape-retaining frame, is completely eliminated. This makes it possible to mass-produce inexpensive electrically processed foods.

In addition, since raw food material A contains salt with a higher salt concentration than dilute salt solution B, raw food material A becomes 20°C hotter due to Joule heat during ripe heat sterilization, and raw food material It can be seen that material A is evenly sterilized by heat sterilization, and that electric current is distributed evenly through raw food material A to save power consumption.

Moreover, if the raw food material A is an aquatic animal, if a small amount of vinegar is mixed into the dilute salt solution B,
In addition to promoting the electrical conduction of the raw food material A and improving the firmness of the food material A, the odor unique to aquatic animals can be further reduced.

[Effects of the Invention] In short, the present invention employs the above-described method, so unlike the conventional manufacturing method, there is no need for the filling operation of filling and storing raw food materials into the insulating holding cylinder one by one, and for filling the materials. It can be formed into any shape containing salt evenly without the need for subsequent closing work to close the openings on both sides of the insulating holding cylinder and pressing work to press the electrode bodies on both end faces of the current-carrying shape-retaining frame. After storing a large number of raw food materials A in a stacked manner in an insulating storage basket 1 having a large number of current-carrying windows 3 on the peripheral wall 2, the insulating storage basket 1 is stored in an insulating container 7. Moreover, by submerging the raw food material A in a dilute salt solution B having a salt concentration lower than that of the raw food material A, and applying current across the pair of electrode bodies 9, a large number of Is it possible to mass-produce electrically processed foods with good taste by subjecting raw food material A of any shape to heat sterilization all at once? Under what conditions can raw food material A be insulated? Even if the raw food material A is housed in the food storage cage 1, the current passes through the raw food material A evenly and intensively, using the dilute salt solution B with a low salt concentration as the current-carrying medium through the numerous current-carrying windows 3. In addition to making it possible to easily obtain electrically processed food that has been uniformly heat-sterilized in a short time while saving power consumption, it is also possible to carry in and out the food material A into the insulating container 7. It has the effect of efficiently achieving the following.
