JP2002065056A - Magnesium-enriched cortinellus shiitake carpophore and method for producing the same - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a method for enriching Cortinellus shiitake carpophore in growth with magnesium by making the Cortinellus shiitake itself absorb magnesium when cultivating it in a mushroom bed system. SOLUTION: This method for enriching shiitake mushroom carpophore in growth with magnesium comprises addition of pulvelized peridotite powder containing much magnesium as one of mushroom bed materials so that the magnesium component in the pulvelized peridotite powder is dissolved in the water in the materials so as to make the Cortinellus shiitake absorb the dissolved magnesium.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fruit body of shiitake mushroom with an enhanced magnesium content in a fungal bed cultivation, and a method for producing the same.

[0002]

2. Description of the Related Art Conventionally, shiitake mushrooms have been widely used as health foods. In recent years, besides using it as a cooking ingredient,
Numerous products obtained by adding shiitake mushrooms processed by drying, crushing, etc. to health supplements are also on sale.

Under these circumstances, Japanese Patent Laid-Open No. 10-07573 is disclosed.
No. 9 discloses a method for obtaining a mycelium of a mushroom having a mineral content, which is apt to be lacking for Japanese people, a high nutritional value, and a convenient form such as a pellet.

[0004]

However, there is no disclosure of a method for enhancing the mineral content by absorbing the mushroom itself, which is a fruit body that is the original form of the mushroom that is easily understood by consumers. We examined whether magnesium in a certain peridotite powder could be used.

[0005] That is, the peridotite fine powder is in a state suitable for uniformly mixing with materials such as sawdust, nutrients, and water at the time of producing the bacterial bed, and the magnesium content in the fine powder is dissolved in water. The purpose of the present invention is to provide shiitake mushrooms having a higher added value than conventional products, focusing on the fact that shiitake mushrooms are easily absorbed.

[0006]

Means for Solving the Problems By adding fine powder of peridotite containing a large amount of magnesium to the fungal bed material, the amount of magnesium in the shiitake mushroom fruit body generated is enhanced,
The above problem has been solved.

FIG. 1 is a diagram showing the inside of a fungus bed having peridotite fine powder before inoculating Shiitake mushroom fungi. 2, further composed of peridotite fine powder 3, vegetable processing residues 4 generated during the production process of gallic acid, and water 5. Here, the magnesium content in the peridotite fine powder 3 is dissolved in water, so that the mushrooms can be absorbed.

Next, a method for producing a bacterial bed will be described. First, sawdust 1, nutrient 2, peridotite 3, processing residue 4,
A predetermined amount of water 5 is mixed with a mixer. Next, the mixed material is transferred to an automatic filling machine by a conveyor, and the culture bag is filled in a fixed amount.

Next, the bagged mixture is sterilized in a sterilizing pot,
After cooling to 18 ° C., Shiitake fungi are inoculated in the inoculation room. After inoculation, the culture bag is immediately sealed to prevent invasion of various bacteria, and is immediately shipped or, if necessary, cultured in a culture room and then shipped.

Here, the fungal bed is mainly made of sawdust of broad-leaved trees such as beech and oak, but it is becoming difficult to obtain it year by year due to a decrease in forest resources and a corresponding increase in protection. . Therefore, although there is a pressing need to develop new materials, here, the processing residue 4 which is waste in a different field is employed. In addition, since the peridotite fine powder 3 is also a waste, cost reduction was achieved.

[0011]

The bacterial bed constructed as described above contains a large amount of magnesium in the shiitake mushroom fruit body produced by adding a magnesium-containing component, which is easily absorbed by shiitake mushrooms, to the bed material, ie, peridotite. Act like so.

Here, the peridotite fine powder 3 is waste generated in the process of producing crushed stone used in the civil engineering industry.

The mixing time in the mixer is preferably about 1.5 hours, and the sterilization time of the bacterial bed is preferably 9 to 13 hours at 95 ° C. or higher. Time is optimal.

At the request of the customer, the bacterial bed inoculated with Shiitake fungi is shipped immediately after inoculation alone, and is shipped and sold after 30 days for a temporarily cultured product and 110 days for a fully matured product.

As described above, the use of waste as a fungal bed material effectively acts such as effective use of resources and low-cost, high-value-added shiitake mushrooms as health foods.

[0016]

Next, an embodiment will be described. Bacterial bed production is 9 per day
In 60, the amount of material sawdust 4.3 m ^3, machining residue 0.5 m ^3, bran 180 kg, Mame殼powder 30k
g, peridotite fine powder 40 kg. Water was added so that the water content of the bacterial bed was 65%. The equipment conditions at this time were as follows: mixing time by a mixer was 1.5 hours, sterilization conditions of the bacterial bed were 103 ° C. for 11 hours, and inoculation conditions were a bacterial bed temperature of 18 ° C. The culture was performed at room temperature for 110 days, and then a temperature shock was applied to promote the development of fruiting bodies.

As a result, the magnesium content of the obtained shiitake mushroom fruit body could be enhanced by about 7.5 times, assuming that the magnesium content obtained by the conventional bacteria bed was 1.

[0018]

As described above, magnesium can be strengthened about 7.5 times as compared with the conventional product. As a result, it is effective in maintaining health, particularly in improving the calcium absorption rate, and can contribute to the prevention of osteoporosis.

[0019] Further, the present invention can solve the problem of a place for dumping fine powder generated when producing peridotite crushed stone used in the construction industry.

In addition, the amount of sawdust used can be reduced, which makes it possible to combat inexpensive imported shiitake mushrooms.
