Gaertn) Whole plants or flowers, fruits, leaves, stems, rhizomes are treated by steaming and / or roasting a freeze-ground product in a temperature range of −10 to −80 ° C., and then kneading. It was decided to be a shredded product obtained by drying.

[0005]

The structure of lotus tea according to the present invention will be described in detail below. In this invention, lotus ( N.
nucifera Gaertn). As used herein, the lotus ( N. nucifera Gaert
n) is a perennial aquatic plant cultivated in a pond, a paddy field, a moat or the like. The rhizome of the lotus ( N. nucifera Gaertn) is white and slender, with thickened tips and lotus roots ,
The leaves have long petioles, and there are two types: floating leaves that float in the water and aerial leaves that pull out. The flowers bloom in summer, the petals are ovate and dented in a boat shape, there are many stamens, the calyx is spongy, and many fruits are in the middle of a beehive-like hole. It is widely cultivated over the temperate zone.

Such a lotus ( N. nucifera)
The shredded material of Gaertn) is an essential component. As the shreds, shreds of whole lotus of N. nucifera Gaertn can be used, or shreds of one or more of flowers, fruits, leaves, stems and rhizomes. May be. In addition, especially lotus ( N. nucifera
When using the flower part of Gaertn), it is desirable to use a stamen.

That is, the lotus ( N. nucifera)
Gaertn) has been used as a crude drug since ancient times,
The roots of lotus roots are sword nodes, petioles are prunus, leaf blades are pruned leaves, mature fruits are called stone lotus, stamens are lotus beards, and fruit bulbs are lotus buns. Contains flavones such as. Also, the fruits have methylco
rypalline, lotusine chlori
Alkaloids such as de and dimethylcoclaurine are contained. In the present invention, such an active ingredient is easily ingested as tea every day.

The lotus ( N. nucifera Gaert
As the shredded product of n), a fresh product may be dried and then shredded by an appropriate method. More preferably, the shredded product obtained by the following first to fourth methods is used. It is the lotus ( N. nucifera Gaert)
It is more preferable because the flavor and active ingredient of n) are not impaired and the quality can be maintained for a long time.

In the first method, the lotus ( N. nucify
Ra Gaertn) whole plant, or flowers, fruits, leaves,
One or more parts of stems and rhizomes are dried and shredded in a temperature range of 50 to 70 ° C, and roasted in a temperature range of 150 to 160 ° C for 5 to 10 minutes to obtain tea. Specifically, 50-70 ° C
Lotus ( N. nucifer) obtained by drying in the temperature range of
a Gaertn) whole plant or flowers, fruits, leaves,
One or more parts of stems and rhizomes are appropriately shredded to a size of 1 to 3 cm and roasted. Here, especially 150 to 160
The method of roasting in the temperature range of ℃ is that roasted tea with good flavor can be obtained without losing the active ingredient contained in the lotus by roasting at such a high temperature for a short time. Because you can do it. That is, 150 ° C
This is because if the roasting time is not set to be long in the temperature range below, it is not possible to obtain a tea with a good flavor, and if the roasting time is lengthened, the active ingredient in the lotus may be impaired. 1
In a temperature range exceeding 60 ° C, it is not preferable because it is difficult to set the temperature and the active ingredient in the lotus is lost.

In the second method, the lotus ( N. nucify
Ra Gaertn) whole plant, or flowers, fruits, leaves,
One or more parts of the stem and the rhizome are dried, shredded to an appropriate size, for example, about 1 to 3 cm, and steamed. Steaming is performed with steam or heated steam for the purpose of softening the raw materials. The treatment time is preferably about 10 to 120 seconds, and if it exceeds 120 seconds, the lotus will be deteriorated and coloring and an offensive odor will occur, which is not preferable. Alternatively, the lotus shredded product is roasted without such steaming. This process
150 ° C to 400 ° C in advance, more preferably 200 ° C to 3
In a container heated to 20 ° C., stirring is performed for a required time to avoid partial heating. The treatment time may be arbitrarily selected depending on the dryness of the raw material and the heating temperature. However, when the raw material in a completely non-dried state is used, it is desirable that the temperature is 300 ° C. within a few minutes and 200 ° C. within an hour. .

After that, the roasted lotus pieces are kneaded. This kneading refers to the operation of rubbing the raw materials together while lightly pressing the roasted lotus pieces with a machine or hand. This kneading is performed without heating, and the processing time may be up to the time when it can be judged visually that the twisting of the raw materials is sufficiently completed, usually 1
0 to 60 minutes. This kneading step and roasting step may be combined and repeated as many times as necessary. In this case, it is better to lower the heating temperature in the second and subsequent roasting steps and to shorten the treatment time as compared with the first time. After this kneading step, drying is performed. Drying for about one week in the sun or 40-9
The drying is carried out by heating with blowing air at 0 ° C. In the case of heating air drying
A treatment time of 5.6 hours is sufficient. In addition, in the drying step, heating air drying is more preferable than sun drying in order to increase the flavor. The lotus shredded material thus obtained has no odor or bitterness and has a sencha-like aroma.

In the third method, the lotus ( N. nucify
Ra Gaertn) whole plant, or flowers, fruits, leaves,
One or more parts of stems and rhizomes are freeze-ground in a temperature range of -10 to 80 ° C to obtain shredded products. The lotus contains various alkaloids and flavones, and especially the rhizome contains a large amount of polysaccharides, which makes it highly viscous and difficult to grind, but freeze-grinding in a temperature range of -10 to 80 ° C You can get shreds well. That is, the raw material lotus is dried and finely chopped into an appropriate size.
Shred into an appropriate size with a crusher such as a ball mill in a temperature range of 80 ° C. Here, the temperature range for freeze-grinding is set as described above, because when the temperature is higher than -10 ° C, a good crushed product cannot be obtained due to the viscosity of lotus, while -80 When crushed in the ultra-low temperature range exceeding ℃,
This is because the lotus cell membrane is destroyed and a shredded product containing the active ingredient cannot be obtained, which is not preferable in any case. The obtained freeze-pulverized product is sterilized by ultraviolet sterilization, low-temperature intermittent sterilization, etc., if necessary,
It is considered to be an essential component of lotus tea.

In the fourth method, the lotus ( N. nucify
Ra Gaertn) whole plant, or flowers, fruits, leaves,
Freezing and pulverizing one or more parts of stems and rhizomes in a temperature range of −10 to 80 ° C. is steamed and / or roasted as described above, and then kneaded and dried to obtain shredded products. . In this way, by freeze-grinding the raw lotus first,
The active ingredient can be crushed without damaging the cell structure in the lotus to be contained in the shredded material, and the quality deterioration with time can be achieved by the subsequent steps of steaming and / or roasting and kneading. It can be an excellent lotus tea in which The lotus shredded product obtained as described above may be used as it is as tea, or as needed, Gynostemma pentaphll
It may be mixed with other tea leaves such as um Makino) tea, oolong tea, green tea, dove tea, dokdoku tea, and the like.
