Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a powdered food containing active ingredients such as shiitake mushrooms and dietary fiber from a culture medium made of a material selected from sugar cane or radish and containing a large amount of raw sugar and vegetable fiber. It is something.

Shiitake mushrooms have a unique flavor component, and various medicinal effects have been biochemically proven, including prevention of adult diseases,
It is valued as a healthy food for treatment.

However, fruiting bodies are extremely indigestible and expensive, making it difficult to actually consume a certain amount of them, leaving them as a luxury item.

In addition, in view of these problems, the present inventor first cultivated mycelium such as shiitake mushrooms in a culture medium made of grains such as brown rice or barley, and then dried and crushed the cultured mycelium to produce a powdered food. Although it was developed (Special Publication No. 51-22061),
In the subsequent implementation stage, the powdered food obtained by the above method contains a large amount of carbohydrates such as starch, which is not desirable in the current diet where overnutrition is a problem, and it also has a sweet taste. The problem was pointed out that it is not very popular, especially among sick people and children, because it lacks ingredients.

This invention was made in view of these problems, and sugar cane (cane...hereinafter referred to as sugar cane) or sugar beet (beet...hereinafter referred to as sugar beet) was selected as the culture medium. These materials contain a large amount of vegetable fiber, and the purpose is to cultivate edible mushroom mycelium using a culture medium made of these materials, thereby obtaining a powdered food rich in the active ingredients of edible mushrooms and dietary fiber. That is.

The present invention will be explained in detail below.

The feature of the present invention is that one or two types of plant tissues selected from sugar cane or sugar beet are used as culture materials, and after autolysis of the mycelium, the tissue is pulverized as it is and used for food.

By the way, fiber in food does not serve as an energy source.
Nutrition was not given much importance.

However, recently it has been discovered that indigestible polysaccharides such as fiber contained in plants, that is, dietary fiber, have unexpected physiological effects in the human body, especially in preventing or controlling adult diseases. This has become clear and is now in the spotlight.

On the other hand, non-infectious diseases such as colorectal cancer, arteriosclerosis, and diabetes have been occurring frequently in developed countries in Western Europe, including the United States.

This is because the diet of Western European society has changed significantly over the past 100 years, with the intake of meat, fats, oils, and dairy products increasing, while vegetables and fruits containing fiber have decreased, and people are now consuming highly refined foods. It is assumed that one major cause is that the intake of dietary fiber has decreased.

By the way, our country has recently become more Westernized in its dietary habits, and the dynamics of diseases are also becoming more Westernized.

Here, it would be extremely useful to supply new dietary fiber by utilizing the decomposition ability of edible mushrooms, a material that can only be used primarily as a material for the food industry.

Further, when the above-mentioned culture medium materials are used as a culture medium, they are finely pulverized and dried, and the water content is adjusted to about 50 to 70%.

Furthermore, as a result of the experiment, it was confirmed that the mycelium was sufficiently cultured using the culture medium consisting only of the above-mentioned materials, and it was confirmed that there was no need to add other supplementary nutritional sources such as rice sugar.

Further, the culture medium prepared as described above is placed in a P.P. container and sterilized by heating in a conventional manner, and inoculated with a seed culture such as a shiitake mushroom.

The inoculum to be used may be either liquid or solid, but it is preferable to use a liquid inoculum.After inoculating the inoculum, it may be cultured using a conventional method.In order to promote mycelial growth and culture in a short period of time, the appropriate temperature and humidity should be used. It is more effective to change the light source and perform temperature change treatment after storing the product in an air-conditioned room.

Furthermore, as the inoculum of edible mushrooms used, shiitake mushrooms are the most excellent in terms of activity, nutritional value, etc., but it goes without saying that other mushrooms such as nameko mushrooms and oyster mushrooms may also be used.

When cultured as described above, the mycelium spreads throughout the culture medium, and when the mushrooms reach full maturity, a raised phenomenon occurs on the surface of the culture medium in the case of shiitake mushrooms.

The point at which this upheaval phenomenon occurs is the time when the metabolic activity of the mycelium is most active, and at this time the culture medium is removed from the container and crushed.

The pulverized particles at this time may be coarse.

The crushed culture medium is packed into a box-shaped container, water is added, and the container is sealed.

In addition, the pH of the water to be added is optimally 4 to 5.

After filling the culture medium into the container, heat the container to an appropriate temperature (40°C ~
The reason for the heating is β-1-3 glucanase and chitinase, which are enzymes metabolized by the shiitake mycelium. This is to promote the autolysis of the mycelium (as evidenced by et al.), make the various components of the shiitake mushroom mycelium water-soluble, and allow the various active components of the mycelium to be leached into the culture medium.

Thereafter, the culture medium is further heated, but if the drying temperature is too high, the titer of enzymes will decrease, so the maximum temperature should be kept at 60°C.

After drying, the culture medium is pulverized into a fine powder using a pulverizer.

The powdered food according to the present invention is obtained as described above, and contains a large amount of various active ingredients in the mycelium, that is, flavor components such as free amino acids, and medicinal ingredients, as well as a large amount of dietary fiber. It is effective against colon cancer, arteriosclerosis, diabetes, etc.

Furthermore, since the raw sugar in sugar cane and sugar beet is transferred to the mycelium, the resulting powdered food is rich in sweet ingredients, and therefore has the effect of being able to be provided to sick people, children, etc. without difficulty using chopsticks. .

Furthermore, since it does not contain formaldehyde, which is a harmful substance, it is of course extremely safe.

Examples 1 Sugar cane is crushed and dried, and the moisture content is adjusted to about 50 to 60%, thereby preparing a culture medium.

Then, 1 kg of the culture medium obtained as described above is placed in a heat-resistant P-P bag, a ventilation hole is provided with a cotton plug, and the bag is heated and sterilized to obtain a sterile culture medium.

Thereafter, 20 cc of liquid inoculum of pure deep-cultured shiitake mushrooms is inoculated into this culture medium, and this is stored in an air-conditioned room maintained at a room temperature of 20° C. to 25° C., and cultured for 45 to 60 days.

If a light source of about 100 lux is applied immediately after the Shiitake mycelium has spread into the culture medium, a raised phenomenon will occur on the surface of the culture medium after 1 to 2 days.

Thereafter, this is stored in a low temperature treatment chamber at 0° C. to 4° C. and subjected to low temperature treatment for about 48 hours, and the culture medium is taken out from the P-P bag and coarsely ground.

The crushed culture medium is further stored in a box-shaped container, into which 1.0 OOcc of water adjusted to P-H4.5 is injected, the container is sealed, and heated with a heater for 5 to 6 hours. Promotes the body's self-digestion.

Thereafter, the lid of the container is removed and the temperature is further raised to 60° C. for 1 hour to dry the culture medium.The dried culture medium is then taken out from the container and finely ground into powdered powder using a grinder.

Example 1 Sugar beets are crushed and dried, and the moisture content is adjusted to about 50-60%, thereby preparing a culture medium.

Then, 1 kg of the culture medium obtained as described above is placed in a heat-resistant P-P bag, a ventilation hole is provided with a cotton plug, the bag is heated and sterilized, and 20 cc of liquid inoculum of Oyster mushroom is inoculated therein.

The subsequent culturing, drying, powder processing methods, etc. are all the same as in the previous example, so their explanation will be omitted.

Example 2 Culture medium materials of sugar cane and sugar beet obtained by the same method as in Examples I and 2 were mixed to form culture medium 1! 9- is made, stored in a P-P bag in the same manner as above, and sterilized by heating.

This is then inoculated with a shiitake mushroom inoculum, but the subsequent culturing means, drying and powder processing methods, etc. are all the same as in the previous example, so their explanation will be omitted.
