Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention uses the scientific name "asparasus.
TECHNICAL FIELD The present invention relates to a rooibos tea extract, which is useful as a health drink, a food additive, and the like, which is made of leaves of a plant belonging to the family of conifers (Aspalathus linearis) (referred to as rooibos tea or rooibos tea) and a manufacturing method thereof.

[0002]

[Prior Art and Problems to be Solved by the Invention] This Aspalathus linearis (hereinafter referred to as “Aspalathus linearis”) is a kind of herb that grows only in a plateau area over 450 m above sea level in the Cedarburg Mountains of South Africa. is there. And this plant has the characteristic that it grows only in the harsh natural conditions where the temperature difference between day and night is large on the thin and strongly acidic soil, and its leaves have been used as a traditional medicine transmitted from the native people of South Africa since ancient times. ing.

As its functional component, flavonoids having an SOD-like action having an active oxygen removing effect are contained in about 100 g.
In addition to 37 mg, it also contains abundant minerals, so it contains ingredients useful for preventing adult diseases and aging the skin.

[0004] Particularly, diseases caused by the disturbing action of active oxygen include various inflammations, autoimmune diseases such as Crohn's disease and ulcerative colitis, ischemia such as myocardial infarction and brain attack,
There are many diseases such as arteriosclerosis, gastric ulcer, acute pancreatitis, diabetes and Alzheimer's dementia. And the enzyme made in vivo to remove such active oxygen is SOD,
Further, asparalinea has been attracting attention as having the same function as SOD, that is, having an SOD-like effect.

Therefore, the present inventor previously concentrated a healthy beverage which can be easily ingested by hot-water extraction of asparalinea leaves (rooibos tea) having such excellent efficacy, and concentrated the hot-water extract, and further A powder or concentrated liquid obtained by drying the concentrated liquid for easy use as a foodstuff or a food additive, and a method for producing the same were provided.

[0006]

The present invention provides a concentrate (extract) of a liquid obtained by concentrating the hot water extract of rooibos tea described above.
The present invention aims to provide a stable rooibos tea extract free of precipitation and separation by improving the above condition. That is, the gist of the present invention relates to a rooibos tea extract prepared by adding and mixing oligosaccharides to a rooibos tea aqueous extract concentrate, and a method for producing the rooibos tea extract.

[0007]

The manufacturing process of the rooibos tea extract of the present invention is exemplified as follows.

[0008]

The rooibos extract of the present invention is an apple,
It can be used by mixing with fruit juices such as peach and pine, honey, loam, oolong tea, black tea, green tea and the like, and can also be used by mixing with alcoholic beverages. As another method of water extraction and concentration of rooibos tea, a solution obtained by mixing rooibos tea and an aqueous dextrin solution and heating and extracting the mixture and deconcentrating the extract can be used.

[0010]

EXAMPLES The present invention will be further described below with reference to examples.

Example 1 Aspalathus linealis needles were sun-dried or shade-dried and then shredded, and 9 g of the dried cut product was added to 1 liter of purified water and boiled for 25 minutes.
After cooling, filtration and concentration under reduced pressure gave a Bx40 ° concentrate.
To 30 parts of this concentrate, 70 parts of an aqueous solution (Bx75 °) of oligosaccharide [Mei-oligosaccharide (Fructooligosaccharide) manufactured by Meiji Pharmaceutical Co., Ltd.] was added and mixed to obtain 100 parts of Bx64 ° extract, which was heat-sterilized and then filled while hot.

(Example 2) 0.1% sodium bicarbonate water was added to shredded dried leaves of Aspalathus linealis, and the mixture was heated and extracted at 95 ° C for 1 hour. After cooling, a small amount of sodium ascorbate was added as an antioxidant to the filtrate and concentrated under reduced pressure, and then oligosaccharides were added and mixed in the same manner as in Example 1 to form rooibos extract and then 90 ° C. Heat sterilized for 10 minutes, and filled when hot.

[0013]

INDUSTRIAL APPLICABILITY The rooibos tea extract of the present invention can provide a stable rooibos tea extract product for a long time without separation and precipitation of the precipitate due to the presence of oligosaccharides, though it is a concentrated water-extracted rooibos tea concentrate It was In addition to the pharmacological action of rooibos tea, physiological actions such as intestinal regulating action of oligosaccharides are also taken into consideration. For example, by diluting this by about 60 times, it can be used as a healthy drink or added to food and drink for healthy food and drink. It is suitable as an extract.

Claims (2)

[Claims] 1. A rooibos tea extract obtained by adding and mixing oligosaccharides to a water extraction concentrate of rooibos tea. 2. A method for producing a rooibos extract, which comprises concentrating a hot water extract of rooibos tea under reduced pressure, and adding and mixing an oligosaccharide thereto.
