In general, flammulina velutipes is a mushroom that grows in the stems and stumps of various hardwoods from late autumn to the following spring. The wild species is faintly tan or dark brown. The commercially available top mushrooms are cultivated by bean sprouts, It is not open but has a long, white or creamy color.

The top mushroom is 90% water content, and the other ingredients are protein, lipid, carbohydrate, fiber, potassium, phosphorus, vitamin. The body of the mushroom is covered with cell wall. Cell wall contains cellulose, chitin, chitosan, It contains polysaccharides and monosaccharides such as fucose, arabinose and mannose. Chitosan contains a large amount of β-glucan, which activates the immune system of the body and promotes the proliferation and recurrence of cancer cells. Inhibits blood glucose and blood cholesterol, improves lipid metabolism, inhibits body fat accumulation and accumulation, and promotes blood flow through platelet aggregation inhibiting action.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing a stepwise process for producing a dried mushroom powder according to the present invention;

The present invention relates to a method for drying and crushing powdery mushrooms so as to increase the convenience of carrying and eating while improving the feeling of eating and enhancing the absorption rate of various nutrients in the body by fine powdering, and a method for preparing the dried mushroom powder A steam treatment step for sterilizing the top mushroom which has been selectively washed with water and washed with steam to prevent discoloration during drying while being sterilized, and a step for treating the inside air of the decompression dryer with the decompression pump A step of drying at a low temperature for a certain period of time while sucking and decompressing the water to reduce the moisture contained in the mushroom in the drying process so that the micropores are perforated while being sucked by the decompression; A second drying step of drying at a higher temperature for a short time under an atmospheric pressure, To be pulverized (粗 粉碎) primary grinding step, and the first tank to the pulverized mushroom milling (微 粉碎) powdered which is composed of the second milling, and completion.

Hereinafter, preferred embodiments of the present invention will be described in detail.

1. Steam treatment step

The step of sterilizing the top mushroom which has been washed with water and removed from the base and steamed at 100 ~ 120 ℃ for 10 ~ 40 minutes to prevent discoloration during drying. The selected top mushroom of a certain size is washed with water and various kinds of surface After removing the foreign substance and cutting off the bottom base, it is steamed at 100 ~ 120 ℃ for 10 ~ 40 minutes, so that the moisture of the mushroom is warmed to the outside without getting out, And sterilized.

In this case, when the temperature of the steam exceeds 120 ° C or the steam is applied for 40 minutes or more, the top mushroom is thermally deformed and the nutrients in the inner part are destroyed. If the temperature of the steam is less than 100 ° C or less than 10 minutes When steam is applied, the top mushroom is not uniformly ripened as a whole, causing some discoloration in the drying step.

2. The first decompression drying step

While the steamed mushroom was put into the decompression dryer, the internal air of the decompression dryer was continuously sucked by the decompression pump and the primary drying was performed at a temperature of 35 to 50 ° C. for 8 to 12 hours while the decompression was performed. The step of piercing the fine holes as a whole in the top mushroom as the water contained in the mushroom is sucked by the decompression, the method comprising the steps of: sucking the inside air of the reduced pressure dryer at a pressure of 40 to 60 kgf / The inside of the decompression dryer is decompressed constantly. During the decompression, the internal temperature of the decompression dryer is set at a low temperature of 35 to 50 ° C. From the top mushroom containing about 90% of water, the moisture is sucked in the drying process, The micropores are drilled in a dense manner, and thus, after the secondary drying, By the three holes, when the powder is crushed through a conventional cutter-type crusher, the top-shaped mushroom of the yarn form is warped or easily pulverized in the form of a fine powder having a particle size of 120 to 300 mesh without being bundled together.

On the other hand, when the pressure of the decompression pump is kept below 40 kgf / ㎠ when the decompression pump is decompressed, the water is not drawn from the top mushroom and the fine holes are not punctured. If the pressure of the decompression pump exceeds 60 kgf / And when it is heated to a temperature exceeding 50 ° C in the decompression dryer, the surface of the mushroom is burned, and the mushroom is discolored to discolor, resulting in a deterioration in commerciality and a taste of the mushroom.

It is preferable that the moisture content of the top mushroom after the first vacuum drying step is maintained at 10 to 20% by weight.

3. Second drying step

The step of secondarily drying the decompressed dried mushroom at a temperature of 50 to 70 ° C for 2 to 5 hours, the decompression by the decompression pump is stopped, and the temperature inside the decompression dryer is reduced to the first reduced pressure drying step And the moisture content of the top mushroom is 3 ~ 8 wt%. When the moisture content of the top mushroom is less than 3 wt%, the surface of the dried top mushroom is burned or heat If the moisture content exceeds 8% by weight, the moisture content is too large to cause the particles to be entangled with each other during the pulverization process, resulting in a problem of not being pulverized into a fine powder state.

On the other hand, when the temperature in the decompression dryer is heated to a temperature exceeding 70 ° C, the surface of the mushroom is burned, and the mushroom becomes discolored or blackened, resulting in a deterioration of commerciality and a taste of mushroom.

4. Primary crushing step

The step of first pulverizing the second dried top mushroom to a particle size of 0.5 to 2 mm, wherein the heated top mushroom is naturally cooled at room temperature and dried in an actual form using a conventional cutter-type pulverizer Is first pulverized to an average particle size of about 0.5 to 2 mm, and is easily pulverized into a fine powder form in the second pulverization step.

5. 2nd crushing and finishing step

The step of finely pulverizing and finely pulverizing the first crude pulverized mushroom so as to have a grain size of 120 to 300 mesh in order to increase the texture and the water absorption and the absorption rate in the body, In the case of simple heating and drying treatment at 60 ~ 70 ℃ for 12 ~ 15 hours, fiber-like top mushrooms are bent or aggregated with each other in the pulverization process so that only crude pulverization with a particle size of 0.5 ~ 2 mm is possible. However, in the present invention, fine pores are thoroughly drilled in the top mushroom as a whole in accordance with the first vacuum drying process, so that innumerable pores are formed in cell walls and fibers of the top mushroom, , The crushed top mushroom was crushed to a predetermined particle size and crushed to a finer size without being clumped to each other and had an average particle size of 120 to 300 meshes The finely pulverized top mushroom powder as described above has a soft powder form, which improves the convenience of carrying and eating, and is excellent in texture and texture at the time of feeding, and also has a high absorption rate in the body during ingestion, so that it is included in the top mushroom Various nutritional ingredients are efficiently absorbed.

In addition, the finely pulverized finely divided mushroom powder can be easily ingested at any time by carrying it in a form of powder, or in a form of a ring, which is easily carried around.

Hereinafter, preferred embodiments according to the present invention will be described.
