Description

The present invention relates to a method for extracting a plant fluid from a plant such as buckwheat shoots, flowers or vegetables.

As a conventional technique, squeezing buckwheat shoots to produce a squeezed liquid, and once freezing the squeezed liquid, thaw this frozen squeezed liquid and hold the thawed squeezed liquid at room temperature to obtain lactic acid There has been a method for producing juice using buckwheat buds obtained by fermenting yeast and separating the supernatant of the juice.
JP 2002-209562 A

The above-mentioned conventional ones are designed to produce juice using only the juice of squeezed buckwheat shoots, so that the active ingredients remaining in the squeezed squeezed buckwheat shoots cannot be utilized. there were. An object of this invention is to obtain the novel extraction method of the plant liquid which eliminated the said malfunction by utilizing effectively the component contained in the squeeze residue generated after squeezing.

In order to achieve the above object, the present invention is configured as follows. That is, the invention according to claim 1 squeezes a plant to produce a squeezed liquor and squeezed dregs, and after drying the squeezed dregs, pulverizes them and mixes them in the squeezed liquor. After fermenting, a clear liquid excluding solids is extracted.
The invention which concerns on Claim 2 makes the said plant the buckwheat shoot and / or the buckwheat flower.
In the invention according to claim 3, after the squeezed residue is freeze-dried, it is pulverized and mixed into the juice.

In the invention according to claim 1 of the present invention, the squeezed residue is dried and powdered and mixed in the juice, so that the active ingredient of the plant can be efficiently extracted and the concentration of the active ingredient in the juice is Get higher. That is, by drying the squeezed residue, the concentration of the active ingredient remaining in the squeezed residue increases. Moreover, since the dried squeezed residue is powdered and mixed into the juice, the juice quickly penetrates into the powdered residue and the high-concentration active ingredient remaining in the powdered residue is efficiently transferred to the juice. High plant extract can be obtained.
The invention according to claim 2 can efficiently extract the active ingredients of buckwheat shoots and / or buckwheat flowers and can obtain a drink liquid of buckwheat with a high active ingredient.
In the invention according to claim 3, since the squeezed residue is dried by freezing, miscellaneous bacteria mixed in the squeeze residue is killed, and the squeezed liquid is stably fermented.

Hereinafter, the present invention will be described with reference to the drawings. In the figure, FIGS. 1-6 shows the manufacturing process of the plant extract by this invention, FIG. 1 is sectional drawing which shows the squeezing process of a plant, FIG. 2 is sectional drawing which shows the drying process of squeezed residue, FIG. FIG. 4 is a cross-sectional view showing a mixing process of powdered scum, FIG. 5 is a cross-sectional view showing a fermentation process, and FIG. 6 is a perspective view of a pack containing a plant extract.

In FIG. 1, reference numeral 1 denotes a squeezer, on which a bottomed cylindrical container 3 having an outlet 3 a on the bottom is placed on a base 2, and a perforated plate receiving plate 4 is placed on the bottom of the container 3. . An upper frame 2a is rotatably attached to the upper portion of the pedestal by a fulcrum pin 2b, a motor 5 is attached to the central portion of the upper frame 2a, and a screw 6 projecting downward is connected to a rotating shaft of the motor 5. The support cylinder 7 is screwed to the screw 6, and a disc-shaped pressure plate 8 is connected to the lower end of the support cylinder 7. The pressure plate 8 is slightly smaller than the inner diameter of the container 3 and is fitted in the container 3 so as to be slidable up and down. Reference numeral 9 denotes a locking tool for engaging and disengaging the rotating end of the upper frame 2 a with the gantry 2, and 10 denotes a tank installed below the container 3.

In this example, buckwheat shoots 20 are accommodated in the squeezing machine 1. That is, as shown by the phantom line in FIG. 1, the upper frame 2 a is rotated upward about the fulcrum pin 2 b, the pressure plate 8 is detached from the container 3, and a predetermined amount of buckwheat in the container 3 Accommodate. Next, as shown by the solid line in the figure, the pressure plate 8 is fitted into the container 3 through the upper frame 2a. In this state, the motor 5 is started, the pressure plate 8 is moved downward through the screw 6 and the support cylinder 7, the young shoots 20 near the container 3 are compressed, and the juice 20a is stored in the tank 10. To do. In this case, when about 300 kg of buckwheat shoots are accommodated in the container 3 and squeezed with the squeezing machine 1, about 250 kg of juice 20a is produced.

Next, as shown in FIG. 2, about 50 kg of squeezed residue 21 of buckwheat shoots 20 remaining in the container 3 is transferred to the pallet 12 and accommodated in a freezer 13 set at about −25 ° C. dry. The freeze-dried squeezed residue 21 is pulverized by a pulverizer 15 shown in FIG. 3, and the powder squeezed residue 21 a pulverized by the pulverizer 15 is accommodated in a powder container 16.

Next, as shown in FIG. 4, the powder squeezed residue 21 a accommodated in the powder container 16 is introduced into the tank 10 and mixed in the juice 20 a in the tank 10 as shown in FIG. 5. And stored in a cool room 18 set at about 5 ° C., where it is fermented with beneficial yeasts such as lactic acid bacteria to obtain a plant extract rich in rutin, potassium and vitamins.

Subsequently, the supernatant of the fermented squeezed juice 20a, that is, a clear liquid excluding solids such as the powdered squeezed residue 21a, is extracted, and this is put into an aluminum foil pack in a liquid state as shown in FIG. Filled to make a 19 product pack with plant extract. Alternatively, the water in the plant extract is evaporated to obtain a concentrated liquid or solid extract product.

According to the above embodiment, the squeezed residue 21 is dried and powdered to form the squeezed residue 21a, and the powdered residue 21a is mixed into the squeezed liquid 20. The active ingredient efficiently migrates to the juice 20, the active ingredient contained in the whole buckwheat shoots can be extracted efficiently, and a plant extract containing a high concentration of the active ingredient can be obtained.
In addition, since the squeezed residue 21 is dried by freezing, and this is powdered and mixed in the squeeze solution 20, there are no miscellaneous bacteria in the squeeze residue 21, and fermentation of the squeeze solution 20 is performed stably. become.
