Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a non-boiled edible crushed edible matsutake mushroom which can be edible without crushing or extracting the cell wall. It relates to a method for producing Hime Matsutake. 2. Description of the Related Art Himematsutake is an aggregate of hyphae, and humans consume mushrooms, which are aggregates, and are called fruiting bodies. However, the mycelial wall of Himematsutake was composed of chitin and hemicellulose, and was extremely poor in digestibility and could not be used for food unless heated. [0003] In recent years, its medicinal properties have attracted attention, and they have been taken as health foods. However, since many of the abundant nutritional and medicinal components are accumulated in the mycelial wall, it is difficult to sufficiently remove these components even by heat treatment or extract extraction.
In spite of the fact that it contains useful components, it has not been possible to make full use of it. [0004] On the other hand, it is conceivable to crush the mycelial wall of Himematsutake to take out the active ingredient, and a method of sufficiently crushing the tough mycelial wall has heretofore been proposed. Was not known. Accordingly, an object of the present invention is to provide a food product in which the mycelial wall of Himematsutake is crushed and its active ingredient can be sufficiently utilized. [0005] Under such circumstances, the present inventors have conducted intensive studies and as a result, it has been found that foods meeting the above-mentioned object can be obtained by crushing using a specific rigid medium. And completed the present invention. [0006] That is, the present invention relates to a method for producing Himematsutake from 20 to
Water was added to the resulting Himematsutake powder to form a suspension of 20 to 90% by weight, and the suspension was crushed into a rigid medium having a diameter of 0.5 to 1.0 mm in an amount of 80 to 85 volumes. %. [0007] In order to carry out the production method of the present invention, Himematsutake is first crushed to 20 to 100 mesh. The crushing method is not particularly limited. For example, princess matsutake is roasted at about 80 ° C., sterilized and dried, and the water content is adjusted to 5 to 10%.
A method of pulverizing this using an alpine, a mill or the like can be used. In order to obtain a fine powder close to 100 mesh, freeze pulverization is preferred. [0008] The obtained powder is added with water to a concentration of 20-9.
A 0% by weight aqueous suspension is obtained. If this concentration is less than 20%, the working efficiency of the next step is lowered, the productivity is reduced, and it is economically disadvantageous. On the other hand, when the content exceeds 90% by weight, the rigid medium for grinding and the water suspension of Himematsutake are rotated together in the closed cylinder used in the next step, and the grinding becomes insufficient. Therefore, it is not preferable. [0009] The water suspension of Himematsutake is composed of 8 rigid media.
It is fed into a cylinder that is 0-85% (volume) full. The diameter of the rigid medium is 0.5 to 1.0 mm, and the material is preferably zircon or zirconia beads.
The rigid medium is used in an amount that satisfies 80 to 85% by weight of the inner volume of the cylinder. However, if the amount is outside this range, the crushing efficiency and productivity will deteriorate, which is not preferable. The Himematsutake water suspension is rotated and mixed with the rigid medium by the rotating blades. This rotation / mixing destroys the Himematsutake cell wall by the grinding action of the rigid medium and the rotating blades, but at the same time generates heat. If left untreated, the quality of the resulting Himematsutake fine powder deteriorates, so the temperature must be kept at 50 ° C. or lower. In order to keep the temperature at 50 ° C. or lower, measures such as cooling the Himematsutake water suspension in advance or providing a cooling device such as a cooling jacket outside the cylinder are performed. The material of the rotating blade is preferably hardened steel, stainless steel, or alumina, and the shape is preferably a disk shape with a barbed cut, and the rotation speed is 2,000 to 2,000.
It is preferred to be 3,500 rpm. The apparatus for carrying out the manufacturing method of the present invention includes:
A continuous wet pulverizer equipped with a cooling jacket is preferred, and commercially available products are DYNO-MILL, Willy A. Bach
ofenAG Maschinenfabrik) are preferred. When using a dyno-mill, the flow rate of the suspension is 5 to 150 l /
hr is preferable. [0012] The slurry of matsutake mushroom obtained as described above is commercialized through the following drying step. Drying is not particularly limited as long as the method does not alter the Himematsutake fine powder, but industrially, vacuum drying is preferred. In addition, since the slurry has increased tackiness, it may adhere to the dryer body during the drying process and burn. Therefore, an anti-adhesion agent such as carboxymethylcellulose (CMC) microcrystalline powder is used for 10 to 15 minutes. %
It is preferred to add. Further, the temperature at the time of drying using a reduced-pressure drier is preferably set to 40 to 60 ° C. The thus obtained fine powder of Himematsutake has a cell wall which has not been destroyed at all by the conventional method, and its particle size is about 90% or more and 350 mesh or less. According to the production method of the present invention, since the tough cell wall of Himematsutake can be destroyed, the active ingredients in the cells can be fully utilized. Next, the present invention will be described in more detail with reference to examples, but the present invention is not limited to these examples. Example 1 1 kg of collected princess matsutake was roasted at 80 ° C. for 120 minutes.
Sterilization and drying were performed to reduce the water content to 11 to 12%, and this was pulverized for 5 minutes using Alpis to obtain 5 mesh. The ball mill (Milt No. 2B, manufactured by Yamamoto Tekkosho Co., Ltd.)
(G), and pulverized for 5 minutes to obtain 450 g of 50-mesh princess matsutake powder. The loss was 5% when calculated assuming that the water content of Himematsutake before crusher crushing was 60%. Observation of the obtained princess matsutake powder with an electron microscope revealed that the princess matsutake cells had not been destroyed yet. Water was added to the princess matsutake mushroom powder thus obtained to prepare a princess matsutake / water suspension having a concentration of 10%, and the temperature was adjusted to 10 ° C. Next, the suspension was fed at a flow rate of 15 l / hr into a dyno-mill in which zircon beads having a diameter of 0.5 to 1 mm were sealed at 80% of the capacity of a sealed cylinder. The hardened steel blades were rotating at 3200 rpm in the closed cylinder, whereby the zircon beads and the suspension were rotated and mixed to grind the Himematsutake cell walls.
At this time, a cooling jacket was set at the same time to adjust the temperature.
As a result, a princess matsutake slurry at 50 ° C. in which the cell walls were completely ground was continuously obtained. Next, after cooling to 5 ° C. from the cooler, it was stored in a tank and added to Himematsutake slurry.
After adding 0% of CMC as an antiadhesive agent, a Himematsutake fine powder was obtained using a reduced-pressure low-temperature dryer. 90% or more of the obtained Himematsutake fine powder had a size of 350 mesh or less. When the soluble nitrogen-free substances (sugars) of the princess matsutake before and after crushing in the above method were measured, it was 27.0 g / 100 g before crushing and 41. It rose to 9 g / 100 g. This means that the Himematsutake powder obtained by the method of the present invention can effectively utilize its components when taken.
