Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a method for processing Gypsophila.

(Conventional technology) The graminthia vulgare is an edible cucurbit plant and a climbing perennial that can be found anywhere in the mountains and fields of Japan.The leaves are picked, dried in the shade, and brewed as gynecology tea, which is drunk as well. It is well known that it is used as a so-called health tea, such as being used as a sweetener for people such as men.

Conventionally, Gypsophila tea has been prepared by drying wild or cultivated Gypsophila in the sun or in the shade, then shredding it into powder, brewing it, and making it drinkable. Further, as a conventional technique, for example, there is one described in Japanese Patent Publication No. 59-33337. This prior art technique involves the steps of (a) steaming finely chopped fresh leaves and/or stems of Gypsophila with steam in a steaming container, and (b) steaming them in a porcelain or metal container heated to approximately 150 to 400 degrees Celsius. subjected to at least one step of roasting with sufficient agitation in an open container, followed by (c) thorough rolling of the treated leaves and/or stems, and (d) about 40 degrees Celsius to 90 degrees Celsius. This is a method of processing Jiaogulan, which consists of drying it for one to several hours and, if desired, pulverizing it to obtain a processed product of Jiaogulan.

(Problem to be Solved by the Invention) Similar to conventional general green tea, raw Physophylla vulgare is sun-dried or shade-dried, shredded, powdered, and brewed, and the tea leaves are yellow-green in color. However, it lacked the refreshing aroma unique to tea, and had the drawbacks of leaving a particularly grassy smell. In addition, the processed products processed by the above-mentioned conventional technology have advantages such as having a sweet taste with less bitterness and eliminating the grassy smell. Therefore, for example, it is generally not suitable for people who like oolong tea, and as a product for the general public to improve their health, it is desirable to have a syringe tea with a color that is also liked by such people.

(Means for Solving the Problems) In order to solve the above problems, fresh, raw Gynathos japonica is cut into pieces of about 3 cm length, and the pieces are left to wither in the sun for 60 to 90 minutes, and then subjected to artificial withering. Wilt in the machine for 30 minutes. Next, it is rolled in a rolling machine for 10 to 15 minutes, and then in a continuous dryer at 70 degrees Celsius.
The first drying is done by drying for 10 to 15 minutes at 35 degrees Celsius for 15 minutes, the second drying is done by rolling for 90 minutes to 180 minutes at 35 degrees Celsius to 40 degrees Celsius using a medium-type dryer, and then the drying is done for 15 minutes to 30 minutes at 95 degrees Celsius using a continuous dryer. A method was taken to process the semi-fermented Physalis through each step of the third drying process.

(Function) By taking such a method, the raw Jiaogulan is withered in the sun and in an artificial withering machine, and then rolled in a rolling machine to condense the moisture content and facilitate semi-fermentation, which further improves the quality of the first and second stages. Through the second and third drying and milling process, a semi-fermented gypsophila tea with a color similar to oolong tea and a good quality product with a good aroma can be obtained.

(Example) A method for processing semi-fermented Gypsophila (hereinafter referred to as the present processing method), which is an example of the present invention, will be described.

This processing method is performed by the following steps.

(1) Shredding process of raw Gypsophila (2) First withering process (3) Second withering process (4) Rolling process (5) First drying process (6) Second drying process (7) Third drying process ( 8) Product packaging process (1) Shredding process of raw Physophylla cranium Live Physophylla cranium that is found freely in the mountains or fields or cultivated is shredded into pieces of about 3 cm length using a known shredder to prepare for the processing process.

(2) First withering process Withering is an operation that reduces the water content of tea leaves through evaporation, but it is not just drying that removes water, but also requires consideration to bring out the flavor. In this processing method, the first withering step involves withering in the sun for about 60 to 90 minutes.

(3) Second withering process In the second withering process, the pieces are put into an artificial withering machine and withered for about 30 minutes. Artificial withering machines are well known, but for example, they are rotary bamboo basket cylinders, with a diameter of 1 m and a length of 3.5 m and an inclination angle of 2 to 3 degrees.
It is preferable to use one that rotates at 15 degrees per minute.

(4) Rolling process Rolling is a process in which the tea leaves are rubbed to homogenize the moisture content and facilitate fermentation. In this processing method, fine pieces of raw Physcomitrella japonica are rolled into a second layer using a known rolling machine.
After the withering process, the dough is rolled for 10 to 15 minutes for semi-fermentation. For example, a kneading machine with a load of 80 kg is used.

(5) First drying step Next, a known continuous drying process was performed at 70 degrees Celsius for 10 minutes.
Fermentation is stopped at this stage by drying for 1 to 15 minutes.

(6) Second drying process Next, drying is carried out at 35 to 40 degrees Celsius using a known medium kneading machine.
Dry in mild hot air for 90 to 180 minutes.

(7) Third drying step: Next, dry at 95 degrees C using a known continuous dryer.
Allow to dry for 15 to 30 minutes.

(8) Product packaging process The fine pieces that have been processed and finished in the style of oolong tea through the above steps may be further powdered as desired, or the required packaging can be performed to obtain a semi-fermented Gypsophila tea product. .

(Effects of the Invention) Since the present invention is configured as described above, by applying the processing method of the present invention to Gyphos vulgare tea, raw Gyphos vulgare with a water content of about 90% can be made with saponin as an active ingredient without a grassy taste and with a water content of about 3%. It has the effect of producing a large amount of fragrant, high-quality product with a oolong-like color tone that does not impair its content.
