Description

[Detailed description of the invention]

[Industrial Application Field] The present invention is directed to, for example, a food material made of polished rice, wheat, other grains, or processed grain products, etc., in which electrolyte solution is directly passed through the food material. This invention relates to a method for electrically processing food that can be processed by heat within a short time and immediately served as a flavorful and delicious food. [Prior Art] In general, food materials such as white rice or other grains or processed grain products are stored in a container such as a pot or a pot under water submersion, and then the food materials are heated by external indirect heating means. Processing methods for obtaining boiled foods have been practiced for a long time and are well known, without mentioning the precedent of this application. [Problems to be Solved by the Invention] By the way, when it is attempted to obtain food by boiling means using mere indirect heating from the outside, as in the conventional processing method of this type, a considerable amount of time is required for boiling. Since it is not possible to easily obtain food that has been boiled within a short period of time, it is also not possible to change the ingredients of the food ingredients themselves, so it is not possible to easily obtain delicious food that has a chewy taste that is different from conventional foods. There was a problem. In the present invention, a food material housed in an insulating container containing an electrolyte solution made of diluted salt water is heated through the electrolyte solution by applying current between a pair of electrodes to which a contact body made of a water-absorbing material is attached. The purpose of this technology is to accurately distribute food directly through food materials and process it in boiling water within a short time using the heat generated by energization, thereby obtaining flavorful and delicious food. [Means for Solving the Problems] In order to achieve the above object, in the method for electrically processing foods of the present invention, opposing surfaces 101a, 101
b, electrically connected bodies 103 and 10 made of water-absorbing material, respectively;
An insulating container 101 equipped with a pair of electrodes 102, 102 having a wire attached thereto is prepared. Next, in the insulating container 101, a food material A made of, for example, polished rice, wheat or other grains or processed grain products, and an electrolyte solution B made of dilute salt water in an amount equal to or slightly larger than that of the food material A are placed.
is housed in an insulating container 101 with a steam reservoir chamber 107 formed between the lid 104 and the lid 104 fitted over the insulating container 101. Then, the food material A contained in the insulating container 101 is quickly processed by the energization effect applied between the pair of electrodes 102, 102, and a part of the steam stored in the steam reservoir chamber 107 is removed. It was spouted outside. [Function] Now, we are attempting to process food material A made of white rice, wheat, other grains, or other processed grain products within a short time by applying electricity, and at the same time, to easily obtain delicious processed foods that are chewable and taste good. If you do,
First, the upper surface is opened, and the opposing surfaces 101a, 10
A food material A made of polished rice, wheat, other grains, processed grain products, etc. is placed in an insulating container 101 in which a pair of electrodes 102 and 102 are respectively arranged in the container 1b.
A lid 104 in which an equivalent amount or a slightly larger amount of electrolyte solution B is fitted onto the insulating solution 101.
After storing the food material A in a state where a steam reservoir chamber 107 is formed between the food material A and the electrolyte solution B
If electricity is applied across the pair of electrodes 102, 102 as a current-carrying medium, food material A and electrolyte solution B
Both are heated by the Joule heat generated by energization, and when a certain temperature is reached, boiling water from inside is ejected from the entire surface of the submerged food material A, stirring the food material A moderately and further raising the temperature. The generated steam is stored in the steam reservoir chamber 107 and then ejected to the outside, and at the same time, it gradually expands and softens due to the action of electricity, and its components are also changed, resulting in a slightly different and delicious processed food. [Example] An example of a manufacturing apparatus for carrying out the method of the present invention will be described with reference to the drawings. 1 and 2, reference numeral 101 denotes an insulating container made of an insulating waterproof paper material and having a bottomed box shape with an open top surface;
A pair of left and right electrodes 102, 102 having electrically conductive bodies 103, 103 made of a water-absorbing material attached to their surfaces, respectively, are inserted into and removed from the opposing surfaces 101a, 101b. Reference numeral 104 denotes a lid that is removably covered on the open top side of the insulating container 101, and the lid 104 has a steam outlet 105 opened therein, and the tip side is inserted into the insulating container 101. Temperature detection needle 1
06 is installed. Inside the insulating container 101, there is a food material A made of white rice, wheat, other grains, or processed grain products.
and an electrolyte solution B consisting of dilute salt water with a salt content of 0.5%, which is equivalent to the food material A or about 20% more than the food material A. Therefore, the processing state of the food material A is detected by the temperature detection needle 106. 107 is a steam chamber formed between the food material A and the electrolyte solution B housed in the insulating container 101 and the lid 104;
The steam generated by the boiling water effect caused by electricity is stored in the tank. Therefore, by the method of the present invention, the
After 200 g of polished rice and 220 g of an electrolyte solution consisting of dilute salt water with a salt content of 0.5% are stored in an insulating container 101, the open side of the insulating container 101 is covered with a lid 104, and food material A and electrolyte solution B are placed inside the insulating container 101.
Insert the temperature sensing needle 1 so that the tip side faces approximately the center of the
06 is inserted. Next, a pair of electrodes 1 respectively disposed on opposing surfaces
If an alternating current of 2A is applied between 02 and 102,
As the temperature gradually rises from the initial temperature of 20℃, the amount of current increases, and when air bubbles rise from the upper layer of polished rice at a temperature of about 55℃, the alternating current increases to 4A, and after starting the current flow,
Food material A is heated to 100°C in 5 minutes. Therefore,
If the electricity is continued as described above, the steam generated by the boiling water will be stored in the steam reservoir chamber 107, and then a part of it will be ejected to the outside from the steam outlet 105, and the polished rice will absorb the heat generated by the electricity. While being heated, it absorbs electrolyte solution and gradually becomes swollen and soft. As the electrolyte solution is gradually absorbed in the manner described above, the electrolyte solution B containing salt in the electrical contact bodies 103, 103 attached to the surfaces of the pair of electrodes 102, 102 gradually decreases, and at the same time, the amount of current applied decreases. Approximately 15 minutes after the start of electricity, the current level dropped to the initial level.
It drops to 2A. Therefore, I turned off the electricity and opened the lid 10.
4 and the pair of electrodes 102, 102 to which the electrical connection bodies 103, 103 are attached are taken out from the insulating container 101, then the insulating container 101 is folded with the upper side facing inward, packaged, and steamed for a while. This is because the electrically processed food can be obtained because of the heating effect caused by the direct electrical current, and although the electrically processed food has good carvings, it is less sticky and the more you chew it, the more delicious it becomes. Note that by mixing other desired ingredients and seasonings into the above-mentioned white rice, delicious mixed rice can be prepared. Next, the results of a component analysis test of a food processed by electrical processing obtained by the method of electrical processing of food according to the present invention published by the Japan Food Research Center are as follows.

[Table] Among the above component analysis test results, the degree of gelatinization, protein,
Regarding the content of carbohydrates and energy, we conducted a comparative test of foods processed by electrical processing obtained by the method of the present invention and foods obtained by electric kettle using materials under the same conditions as the method of the present invention, and the results are shown in the table below. As shown, the food processed by electrical processing obtained by the method of the present invention has a higher content in terms of degree of gelatinization, protein, carbohydrate, and energy, and is even more delicious than the food obtained using an electric oven. was proven.

[Table] [Effects of the Invention] In short, the present invention provides opposing surfaces 101a and 101b.
electrically conductive bodies 103, 103 each made of a water-absorbing material;
Food material A and food material A are placed in an insulating container 101 equipped with a pair of electrodes 102, 102 attached with
Electrolyte solution B consisting of dilute salt water in an amount equivalent to or slightly larger than that is housed in a state where a steam reservoir chamber 107 is formed between the lid 104 fitted on the insulating container 101. After that, the food material A was quickly processed by applying electricity across the pair of electrodes 102, 102, and part of the steam stored in the steam reservoir chamber 107 was blown out to the outside. The contact between the pair of electrodes 102, 102 and the electrolyte solution B is maintained by water-absorbing electrical contact members 103, 10.
3, it is possible to properly adhere the electrolyte solution B made of dilute salt water to the pair of electrodes 102, 102 and promote the energizing effect. The taste of the food is further improved compared to the conventionally well-known energization processing method, and delicious energization-processed foods can be produced in a short time by changing the food material by the action of energization that directly and accurately flows through food material A through B. Not only that, but also the appropriate steam pressure and heat in the steam reservoir chamber 107 make the heating state even better, and it is possible to obtain a more delicious electrically processed food.
