Abstract

PURPOSE:To prevent the browning of MISO (fermented bean paste), to suppress the proliferation of microorganisms, and to keep the MISO in high quality, by putting MISO in a impermeable cup vessel, placing an oxygen scavenger in the space of the vessel, and sealing the vessel. CONSTITUTION:An impermeable cup vessel 1 is manufactured, e.g. by forming a sheet obtained by laminating a film such as polyvinylidene chloride, polyvinyl alcohol, etc. to a sheet of e.g. polystyrene, polypropylene, etc. MISO 2 is put into the vessel 1, and an oxygen scavenger 4 such as a sulfite, rongalite, etc. is placed in the space 3 of the vessel, if desired in a chamber made of a permeable plastic 6, etc. The vessel 1 is sealed with an impermeable lid 5.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for preserving miso! For details, see Non-J
l! ! This invention relates to a method for preserving miso, which involves placing miso in a cup-shaped container and sealing the container with an oxygen scavenger present in the space.

Miso is an expensive source of protein for Japanese people, and has a high protein content.
Conventionally, miso is a product with a high salt concentration to prevent spoilage. [,7
However, in line with the recent trend toward lower salt intake for alcoholic beverages, miso with a lower salt content is now preferred. On the other hand, there was a trend toward a preference for white color in the color of the song. In this way, due to the low chloride or white coloring of miso, the appearance of spoilage or rotten miso has become common.

The present invention relates to a method for preserving miso to prevent deterioration such as spoilage or browning of miso.

By the method of the present invention, it is possible to preserve miso with good taste for a long period of time. As a way to preserve miso
i Conventionally, the method used was to place the bag in a plastic bag, prick it closely, and then fill it with gas or vacuum pack it, but in this case, it is difficult to completely remove oxygen, so it may be necessary to use the gas filling or vacuum bag method. However, it had the disadvantage of requiring extensive machinery and equipment. A disadvantage of tx bagging is that when using miso, it is generally necessary to transfer it to a container before using it, without using the whole bag. Recently, in order to eliminate the drawbacks of such bagging, a method has been introduced in which miso is stored and used in a cup-shaped container. However, in this case, it is difficult to fill the cup 7-shaped container with miso, and the disadvantage is that there is a space at the top of the container. If a space is created inside the container in this way, a browning phenomenon occurs on the IR surface of the miso, which is known as the air inside the container, causing a trap or a phenomenon in which microorganisms multiply and IIklw is eaten. The purpose of this method is to prevent browning of miso, suppress the growth of microorganisms, and maintain good quality of miso.

In the present invention, the non-escape cup-shaped container is 1
For example, a container is used in which a polystyrene base material is used as a base material, and a polyvinylidene chloride or polyvinyl alcohol thread film is laminated thereon. Also, if there is no fee to increase the shelf life of 1k, a container made of polyvinyl chloride is used. Also, there is no particular restriction on the shape of the cup of the cup-shaped container, and a cup-shaped container with a capacity of 2I1m and 1& is used.The size of the cup-shaped container is 500f~8 It is generally thick enough to fit the miso, but it is preferably large enough to fit the miso around 1 o'clock.

Examples of miso preserved by the method of the present invention include white miso, Akami Ivi, or rice 1111 according to other classification methods.
．． In the method of the present invention, which includes all types of miso such as barley-flavored and q-flavored miso, a method for making an oxygen absorber exist in the space of a cup-shaped container containing miso includes, for example, adding an oxygen absorber to the miso. Directly on top! #：Method: Place a polyethylene film on top of the miso, place a layer of laminated paper on top of it, put an oxygen scavenger device on top of it, and place a lid on it to seal the cup-shaped container. There is a ventilated compartment for storing the oxygen scavenger in the compartment, and the oxygen scavenger 1'
It is possible to make the oxygen absorber exist in the space by a method of storing the container or a method of attaching the oxygen absorber to the lid.

Warm temperature for preserving miso in the method of the present invention! Although t is not limited to a specific IC, it is preferably a temperature below room temperature.

As an oxygen absorber in the present invention! Il! Benken acid salt - Zengen acid hydrogen salt, thiomate salt, east dinaonic acid salt.

/New IIHJ! , pyrogallol, ro/galit, gutsu 1 course, wA amine monolith, ascorbic acid, roncalit, dulcose, iron powder, zinc alloy, etc.
It is possible to use any composition containing as the main ingredient. The #R-removed material is usually packaged with a breathable packaging material, but in this case, the preferred breathable packaging material is Shiriba I, which is laminated with a perforated plastic film or a microporous film. It is of course possible to use an alkaline agent together with an oxygen absorber if there is a fee excluding carbon dioxide gas generated.In the present invention, when sealing a container, the sealing Pi fl
: Fi valley container, method of sealing 1& made of non-breathable plastic by adhesive or fusion method, or 7j
For this purpose, a method is adopted in which a non-breathable brass nylon sheet casing film is sealed to @#M by a well-known method such as gluing or fusing.

In this case, it is possible to make the oxygen absorber exist in the space of the container by attaching the oxygen absorber to the circular surface of the film sheet 1 and sealing the container.

In the present invention, miso to be preserved is preferably miso that has been aged, but if miso is not aged, carbon dioxide gas is generated, so in this case it is preferable to use a carbon dioxide absorbent.

As a method for stopping the ripening of miso, for example, a method of adding alcohol to the miso, a method of heating the miso, etc. are employed.

As described above, the method of the present invention exhibits excellent effects in preserving miso; however, it is of course possible to use the method of the present invention in combination with the gas filling method or the vacuum packing method.

The drawings are schematic diagrams for illustrating an example of the method of the present invention.

Figure 11g1 shows a case in which the present invention is carried out by constructing a compartment with one plastic having a vent hole in the lid to prevent moisture from flowing back, and storing an RC decoupling agent in this compartment. Figure 2 shows the case where an oxygen absorber is attached to the lid - In Figure VC, 1 is a non-breathable cup-shaped container, 2 is miso, 8 is a space in the container, 4ti oxygen absorber, 5 is for watching, 6t
i indicates a compartment made of anaerobic plastic, and 7 indicates a micropore.

Next, the present invention will be explained in detail with reference to Examples.

Example: Flavor 11w1Kg in a cup-shaped container with gas barrier properties made of polyethylene/vinyl chloride/polyenalene laminated film.
Add Ageless F8G (oxygen scavenger made by Mitsubishi Marukoma Chemical) to it, and store it at room temperature for 1 month with the amount of vinylidene chloride/polyethylene laminated film. The flavor was evaluated by sensory evaluation. As a control, a phoneme gas 11 exchange plot was set up and stored under the same conditions, and the results are shown in the table below.
