According to the above-mentioned conventional cereal fermentation method on an industrial scale, the white rice for fermentation is prepared by adjusting the water content (immersing) and steaming it into steamed rice without adding rice koji or sake mother. Even though alcohol fermentation was not possible and it was thought that it could not be used for the production of fermented products, it had the disadvantage of consuming a large amount of heat energy for steaming fermented white rice, and such Naked steamed rice has a problem that it is difficult to handle in terms of calories and viscosity.

To ferment cereals,
It is said that on the outer surface of the cereal, a large number of holes and cracks (hereinafter, simply referred to as cracks) for the action of microorganisms and enzymes that ferment and decompose the cereal need to be present. After steaming, it was used for the fermentation process. That is,
It was thought that in order to form the cracks, the cereals had to be steamed with moisture. However, the present invention has been made based on a new finding that cracks can be formed in the grains simply by irradiating microwaves, and a water washing step of washing the grains with water is performed. After that , the grain is held in a closed space.
In this state, the microwave treatment step of irradiating microwaves is repeated a plurality of times, and the fermentation step is performed by performing a temperature control step of adjusting the temperature of the grain to a temperature at which the grain can be fermented. Increase the moisture content of the grain,
The purpose of the present invention is to suppress the burning of the grains in the microwave treatment step, and the operation and effect are as follows.

[Function] In other words, it has been found that the grains are adjusted to an appropriate water content by the washing process of washing the grains with water, and the grains are scorched by the microwave treatment process. The moisture content of the kernel is increased so that inconvenience can be suppressed, and the microwave is efficiently applied to the kernel when the microwave is irradiated. After that, by performing a microwave treatment step of irradiating microwaves, many cracks are formed on the outer surface of the grain,
The action of microorganisms and enzymes that ferment and decompose the cereals is facilitated, and thereafter, the temperature is simply adjusted (usually, if a microwave treatment step is performed, the cereal grains are heated, and thus a cooling step is performed). Is subjected to a fermentation step of fermenting. Furthermore, the starch of the grain undergoes so-called "gelatinization" by microwave irradiation in the microwave treatment step, so that fermentation in the fermentation step is facilitated.

In other words, in forming a large number of cracks on the outer surface of a grain, when steaming the grain as in the conventional method,
A large amount of water must be heated to a high temperature, which entails large energy consumption.However, the fermentation method according to the present invention irradiates microwaves only to the grains that have just been washed with water, and gives energy only to the water contained in the grains. Because it is good, it can form cracks on the grain surface with less energy.

Further, since the microwave treatment step is repeatedly performed a plurality of times, the temperature and the amount of moisture are not changed due to the overheating of the grain and the evaporation of the moisture in each microwave treatment step. The microwave processing step can be performed under appropriate conditions by correcting the appropriate state. That is, the microwave treatment step can be performed while preventing the grains from being overheated or dried and carbonized. So
To irradiate the microwaves to the grains
Since the process is carried out while holding the grain, moisture evaporates from the grain and

It is generally known that the outer surface of a grain contains abundant proteins and lipids, and that such components tend to have a bad influence on the taste of fermented products.
The washing step can remove foreign substances adhering to the outer surface of the grain, remove proteins and lipids near the outer surface of the grain, and further remove the outer surface layer of the grain by the microwave treatment step. When the grain is a rice grain because the lipids contained therein are scattered and the protein is denatured (the configuration according to claim 2), for example, when considering sake brewing, the rice grain may be Compared to steaming and brewing, it can contribute to improving the taste of sake with less labor.

Therefore, a large number of cracks are formed in the grain with only a small amount of energy consumption for irradiating the microwave, and the grain is converted into an easily fermented state without steaming, and is subjected to the fermentation process. Reduces heat energy consumption and eliminates the need for a conventional steaming process for grains, allowing the fermentation process to be performed with extremely simple operations, greatly reducing the labor required for grain fermentation. Cereals can be fermented at a lower cost than before. Furthermore,
In addition to removing impurities adhering to the outer surface of the grain by the water washing process and removing proteins and lipids near the outer surface of the grain, the outer surface of the grain can be removed by the microwave treatment process. Since the lipids contained in the layer are scattered and the proteins are denatured, it is possible to produce good-tasting sake even using inexpensive rice grains, for example, which do not precisely remove proteins and lipids contained on the outer surface. For example, production costs can be kept low, and fermented products can be provided at low cost. In addition, the cereals are sealed
Microwave that irradiates microwave while holding in the space
The process is repeated several times and the grain
Microwave treatment under proper conditions not to heat or dry
It is possible to perform the microwave treatment step while preventing the grain from being carbonized, so that it is possible to suppress the inconvenience that the fermented product taste is reduced due to the carbonization of the grain.
In addition, when the grains are rice grains, handling the microwave-treated rice grains in the temperature control step and the like is easier than handling steamed rice grains in terms of viscosity and the like. Fermentation can be performed more easily than when fermentation is performed.

[0011] In the case where sake is brewed by steaming the rice grains subjected to the microwave treatment as described above without steaming, the conventional method of steaming the rice grains and then subjecting them to the brewing process as hanging rice is used. Compared with sake brewing, it was also found that aroma components (isoamyl acetate and the like) were easily generated, and that sake having excellent aroma was obtained.

From Table 5, it can be seen that although raw white rice s is hardly digested by liquefied enzymes, microwave-treated rice is more easily digested by liquefied enzymes as well as steamed rice. However, as a condition of the microwave treatment, when the microwave irradiation treatment is performed to such an extent that a burning smell does not occur, since there is little change in the ultraviolet absorbance, the decomposition of the white rice s tissue is small, and the amount of glucose produced is high. ,
It can be seen that conditions suitable for fermentation have been obtained.
