Abstract

PURPOSE:To extract from jujubes a juice useful as a new beverage by adding a sugar solution and a denatured alcohol to the raw jujubes, allowing the mixture to stand with stirring sometimes and subsequently separating the extract solution from solid contents. CONSTITUTION:Raw jujubes are mixed with a sugar solution and a denatured alcohol, and the mixture is allowed to stand with stirring sometimes, and subsequently subjected to a solid-liquid separation process to obtain the extract of the jujubes. Specifically, 1000 pts.wt. of raw jujubes, 1000 pts.wt. of a 70-75% sugar solution and 70 pts.wt. of a 75% denatured alcohol are mixed with each other, allowed to stand for 1-2 weeks at room temperature with stirring one of two times a day, and subsequently subjected to a solid.liquid separation process.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates firstly to a method for extracting and producing jujube juice, and secondly to a novel beverage containing jujube juice. Here, "beverage" includes both non-alcoholic beverages and alcoholic beverages.

[0002]

[Problems to be Solved by the Invention] Jujuba is a deciduous tree of the buckthorn family, and dark red elliptical fruits ripen in autumn.
Also, in the Chinese medicine field, it is called Taiju, and it is common to add water etc. to the dried fruits and eat boiled ones to take. Therefore, it takes a lot of time to take a jujube, and there is a feeling that it doesn't fit in with the fast-paced modern life.

[0003] Moreover, it was never attempted to extract the fruit juice, probably because almost all the fruits of jujube were used for food. In addition, the jujube taste is lacking in sourness.

Therefore, one of the objects of the present invention is to develop a method for extracting fruit juice from the fruit of jujuba, and another object is to provide a novel beverage so that the jujube juice can be easily taken. is there.

[0005]

The first aspect of the present invention is a method for extracting jujuba juice, in which liquid sugar and denatured alcohol are added to the raw fruit of jujube, and the mixture is sometimes left with stirring while solid-liquid separation is performed. . Here, the “liquid sugar” means a liquid containing a large amount of sugar, and is a concept including an aqueous solution of sugar, honey and the like.

The second aspect of the present invention is also a method for extracting jujuba juice from the raw fruit of jujuba, but the first aspect is that it is heat-treated first.
Of the present invention.

A third aspect of the present invention is a method for extracting jujuba juice, in which dried fruits of jujuba are shredded, reconstituted with water, added with liquid sugar, left occasionally with stirring, and then solid-liquid separated. .

The fourth aspect of the present invention is also a method of extracting jujuba juice from dried jujuba fruits, but is different in that it is heated after being left standing and then solid-liquid separated.

A fifth aspect of the present invention relates to a beverage, which comprises jujuba juice extracted by the method according to any one of claims 1 to 4. In a preferred embodiment, Yamajuko fruit juice is further added. ing. Here, "Sanzashi" is a deciduous shrub of the family Rosaceae, and its fruits are spherical and red-ripe with a diameter of about 1.5 cm. The dried fruits are used for stomach and intestinal preparation.

[0010]

[Action] Yamazashi juice has a medicinal effect and also has a strong acidity, so when added to jujube juice,
The taste of jujube juice is complemented by a refreshing taste.

[0011]

EXAMPLES Examples of the present invention will be described below.
These are merely examples and do not limit the present invention in any way.

(A) Extraction of jujube juice

(1) Using the raw jujuba juice as a raw material, jujube juice was extracted using two steps shown in FIGS. 1 and 2, respectively.

(2) Using two types of dried jujuba, red jujuba and black jujuba, as raw materials, jujuba juice was extracted using the steps shown in FIGS. 3, 4 and 5, respectively. Here, the red jujube and the black jujuba represent the colors of the dried jujuba, and the contained water is about 34.3% for the red jujube and about 23.9% for the black jujube.

(B) The jujube juice obtained by the extraction method shown in FIG. 1, the Yamajiko juice obtained by the extraction method shown in FIG. 6, and water were mixed in the proportions shown in Table 1 to obtain four types. Beverages were produced.

[0016]

[Table 1]

Table 1 also shows the results of taste tests performed on these beverages. It was found that when Yamadako fruit juice was added in an appropriate amount, the sweetness was suppressed, the taste became refreshing, and the jujube taste was enhanced. If you like,
You can also add Korean carrot juice or honey.

[0018]

EFFECTS OF THE INVENTION The present invention discloses for the first time a method of extracting and producing jujuba fruit juice, and the aim is to take jujube easily at any time and place, and utilize the jujube juice. It is provided in the form of a beverage.

[0019] Jujube and Yamajiko are known as Chinese herbs for their effects and are natural products, so they are healthy drinks that match the recent health boom and have a great effect on health promotion. In addition, the sweetness of jujube and the sourness of Yamajiko are in good harmony, complementing each other and opening a new field in terms of taste, which is very effective.
