[Field of Industrial Application] This invention is applied to Eucommia
moides) and / or a blend of an extract derived from Morinaka leaf and a roasted green tea leaf and / or extract. More specifically, the effect of Morinaka tea and the effect of green tea represented by Hojicha The present invention relates to a blended product of Tonchu-cha and Hoji-cha that combines the benefits and eliminates the odor and taste peculiar to Tonchu-cha with the aroma of houjicha.

2. Description of the Related Art The bark of Eucommia eucommia, which is a deciduous plant native to China, is listed as a herbal medicine in the fine products of Shenno Honzo.

As a medicinal effect of Tochu, the Chinese Medicinal Dictionary and the Chinese Pharmacopoeia "have the effects of supplementing the liver and kidneys, strengthening the muscles and bones, and calming the womb, soreness of the lower back and back, knee and knee atrophy (paralysis of the knee). ),
It cures residual urine, irregular bleeding in women, premature abortion, and high blood pressure. "
Lipid 3.43%, Caffeine 0%, Vitamin C 0
%, Tannin 6%, and geniposidic acid, syringerresinol, pinoresinol di-O-as medicinal ingredients
β-D-glucoside (Pinoresinol-di-O-β-D-gl
Uriside) compounds and other lignan compounds have been reported.

On the other hand, the components of Hojicha are 3.64% total nitrogen, 1.93% caffeine and 1 tannin.
It is known that 4 kinds of catechins containing 0.37% and exhibiting antioxidative action and anticancer action are present, and that roasting gives off a fragrant aroma due to components such as pyrazines.

SUMMARY OF THE INVENTION An object of the present invention is to provide a blended product of Tochu-cha and Hoji-cha, which has the usefulness of both of the above two types of tea.

[0006]

The blended product according to the present invention comprises a mixture of a raw leaf and / or an extract of Tochu tea and a tea leaf and / or an extract of Hojicha.

[0007] Such a blended product is suitable as a drink having a mellow flavor because the offensive odor peculiar to Tochu-cha is erased by the aroma of hojicha.

As the raw leaves of Tochu tea, the current year's leaves are suitable because they can be easily and repeatedly secured in large quantities. However, the raw leaves are not limited to this. Tochu is a deciduous plant, and the collection of autumn leaves is advantageous in that a large amount of material can be easily secured without damaging the trees unlike the collection of bark. However, this is also not a limitation. Tochu leaves are preferably naturally dried.

The Tochu leaf extract is obtained by subjecting the above-mentioned raw leaves to an extraction treatment. A typical example of a solvent for extraction is
Water, especially heated water. Other extraction solvents include lower alcohols such as methanol and ethanol, ketones such as acetone and methyl ethyl ketone, aromatic hydrocarbons such as benzene and toluene, ethers such as diethyl ether and dioxane, chloroform and Examples of the organic solvent include halogenated hydrocarbons such as carbon tetrachloride and heterocyclic compounds such as pyridine. These organic solvents are used alone or in combination of two or more.
Water is preferable as the extraction solvent for using the obtained extract for drinking.

The extraction is usually carried out under heating, but it may be carried out at room temperature. The greater the number of extractions, the better, but usually it is several times.

To prepare an extract from the extract, a method of freeze-drying the extract, passing the extract through an adsorption column to adsorb the components contained in the extract onto the adsorbent, and then adsorbing the desorption solvent onto the same column. The method of desorbing the same component from the adsorbent by passing it through is generally used. In the latter case,
As the adsorbent, activated carbon or a hydrophobic ion exchange resin, for example, DIAION HP-20 manufactured by Mitsubishi Kasei Co. is used. A typical example of the desorption solvent is water-ethanol system. As the other desorption solvent, the above extraction solvent is used. To use the obtained extract for drinking, a water-ethanol system is preferable as the extraction solvent. The desorption solution is then concentrated and the concentrate is dried. Concentration of the desorption solution is preferably carried out under reduced pressure.

Hojicha extract can also be obtained by the same method as in Tochu.

For Tochu tea, both the raw leaves and the extract may be used, or only one of them may be used, and for the roasted green tea, both the tea leaves and the extract may be used, or only one of them may be used.

The mixing ratio of the green leaf and / or extract of Tochu tea and the tea leaf and / or extract of Hojicha is not particularly limited, but the latter is preferably used in 100 parts by weight or more with respect to 100 parts by weight of the former.

[0015]

Next, the present invention will be specifically described with reference to its embodiments.

Manufacture of Tochu leaf extract Tochu leaf picked before falling leaves was naturally dried until the water content became 10% or less. 20g of this Tochu leaf at 95 ℃
In addition to the above 1 liter of boiling water, Tochu leaf was extracted for 5 to 10 minutes. Then, the obtained extract was freeze-dried to obtain about 6 g (about 30% by weight) of the extract.

Production of Hoji Leaf Extract Hoji tea extract was obtained in the same manner as in the production of Tochu leaf extract.

Blended product (1) Tonaka tea raw leaves about 20 g Hojicha tea leaves about 100 g Blended product (2) Tonaka tea raw leaves about 20 g Hojicha extract about 100 g Blended product (3) Tonaka tea extract about 20 g Hojicha tea leaves Approximately 100 g Blended product (4) Tochu tea extract Approximately 20 g Houjicha extract Approximately 100 g Tea pack These blended products have an appropriate amount of tea pack (1.5 ~
5 g) and filled with boiling water, it can be used for drinking as well as known tea.

Stick type After blending these blended products into a granular product by a conventional method,
It can be packed in a stick-shaped packaging container, melted in boiling water and used for drinking.

Retort product These blended products are concentrated 10 times by a conventional method, the resulting concentrate is sterilized by retort, and this is stored as a stock solution. When using this for drinking, dilute it 10 times. This product is suitable for commercial use.

[0021]

EFFECTS OF THE INVENTION The blended product of Tochu-cha and Hoji-cha of the present invention is suitable as a drink having a mellow flavor, since the unusual smell of Tochu-cha is eliminated by the aroma of Hoji-cha.
