Method for preparing persimmon fruit wine {Method for preparing of persimmon wine}

The present invention relates to a method for producing persimmon fruit wine. More particularly, the present invention relates to a method of preparing fruit wine using persimmon juice.

Persimmon is largely divided into persimmon persimmon and persimmon persimmon. Persimmon persimmon is used for year-end and dried persimmon through processing and sweet persimmon is mainly used as raw fruit. Sweet persimmon contains high amounts of flavonoids such as catechin and epicat echin, which are phenolic compounds in green tea, and they are reported to be effective in preventing tissue damage, preventing aging, preventing cardiovascular diseases, and anti-cancer effects. It is. In addition, sweet persimmon is rich in vitamin C, vitamin B complex, vitamin A and minerals, which is one of the foods with high nutritional value.

However, sweet persimmon is mostly used as a pastry, and this causes a problem of discarding when the value of the product as a pastry decreases due to browning or softening during generation and storage of defective fruits due to overproduction and harvesting weather conditions. Therefore, in order to stably produce and consume sweet persimmons it is urgently required to develop a variety of processed foods.

Processed foods using persimmons developed to date include Gochujang (Korean Patent Publication No. 2003-29737 and Korean Patent No. 298953), Snacks (Korean Patent Publication No. 2000-0074877), Canned food (Korean Patent Publication No. 2000) -0067148), beverages (Korean Patent No. 0321644, Korean Patent Publication No. 1984-3010 and Korean Patent No. 333903), 쨈 (Korean Patent Publication No. 1999-0065576) and alcoholic beverages (Korean Patent No. 353379) , Korean Patent No. 349037, Korean Patent No. 149488 and Korean Patent Publication No. 1995-18430) are disclosed.

When preparing alcoholic beverages or beverages using sweet persimmon in the processed food, there is a problem that the yield to obtain a juice from sweet persimmon is significantly low. This is because sweet persimmon contains about 80% water, but because it contains a large amount of viscous material in the flesh, it is difficult to prepare juice by juice.

Therefore, in the past, using a juice of red persimmon rather than sweet persimmon (Korean Patent Publication Nos. 1995-18430 and Korean Patent Publication No. 2003-41126), or using a juice obtained by treating persimmon enzymes with persimmon (Korean Patent No. 149488), liquor was sterilized by heat treatment or acid treatment and alcohol was fermented by crushing the crushed product (Korean Patent No. 349037). In addition, a method of preparing a beverage by putting the persimmons in a storage container and then ripening fermentation for a certain period of time has been disclosed (Korean Patent No. 333903).

However, the conventional method as described above has a disadvantage in that the process is complicated and manufacturing costs and time are high.

On the other hand, persimmon has a low organic acid content and almost no flavor compared to other fruits. Therefore, since the pH of sweet persimmon juice is about 6.5, when alcohol fermentation is carried out using sweet persimmon juice, it may be a problem to cultivate a healthy drunk, which is easy to contaminate with germs early in fermentation. There is a disadvantage that the taste of alcohol is simple.

Accordingly, the present inventors established a preferred method for obtaining persimmon juice with high efficiency, and by adding Schizandrae to persimmon juice, impart proper acidity and aroma of Schizandra chinensis to produce persimmon fruit wine with excellent taste and aroma. .

Accordingly, an object of the present invention is to prepare a fruit juice by crushing and juice the persimmon with a centrifugal juicer in the production method of fruit wine using persimmon, and add Schisandra chinensis to 0.1-1.0% (w / v). It is to provide a method for producing persimmon fruit wine.

Another object of the present invention is to provide a fruit wine produced by the above method.

In order to achieve the above object, the present invention in the method of producing fruit wine using persimmon, persimmon crushed and juiced with a centrifugal juicer to prepare persimmon juice and 0.1-1.0% (w / v) Schizandra chinensis in persimmon juice It provides a persimmon fruit wine production method characterized in that the addition.

The present invention also provides a persimmon fruit wine produced by the above method.

Hereinafter, the present invention will be described in detail.

Methods of preparing fruit wine using persimmons generally include crushing and crushing the persimmons, sucrose step, sterilization step, yeast inoculation and alcohol fermentation step. The present invention is characterized in that in the crushing and juice step of persimmon using a centrifugal juicer to crush the flesh by centrifugal force and at the same time juice the juice. In addition, the present invention is characterized by the addition of Schisandra chinensis to persimmon juice so that the acidity and aroma having Schisandra chinensis. Referring to step persimmon fruit wine manufacturing method of the present invention as follows.

Step 1: Crushing and Juicening

Persimmon used for the production of persimmon fruit wine of the present invention ( Diospyros kaki ) Alternatively, all persimmons may be used, but preferably sweet persimmons are used. First, the harvested persimmons are washed and cut to remove seeds and used as a material for preparing juice. The seeded persimmon pulp is separated from the persimmon pulp by centrifugal force using a centrifugal juicer. Commercially available centrifugal juicers can be purchased and used. In general, the centrifugal juicer breaks down the flesh and at the same time separates the juice from the persimmon pulp by centrifugal force, and the juice and pulp pulp are separated by a metal net.

The inventors of the present invention prepared by using a method of crushing and crushing with a mixer to obtain a persimmon juice, natural leakage of the juice by self-digestion of the flesh and a method of freezing the flesh to destroy the fruit to leak the juice As a result of comparing the amount of juice obtained using the centrifugal juicer and the centrifugal juicer, it was confirmed that the persimmon juice can be obtained in the amount of about 3 to 12 times as much as other methods. (See Experimental Example 1). Therefore, the present invention is characterized by obtaining a persimmon juice using a centrifugal juicer.

Persimmon juice obtained by the above method can be used as it is or by centrifugation according to a conventional method can be used in a transparent juice state in which fine persimmon pulp has been removed.

Second step: adding Schisandra chinensis and sugar

Schizandra chinensis and sugar are added to the persimmon juice obtained in the first step. Schisandra may be purchased and used commercially. It is preferable to add 0.1-1.0% (w / v) of Schizandra chinensis. Most preferably, 0.5% (w / v) is added.

The sugar is added to the persimmon juice added with Schisandra chinensis and adjusted to the appropriate sugar to prepare persimmon fruit wine. The sugar added to adjust the sugar content is not particularly limited, but it is preferable to use sugar or glucose. Most preferably, sugar is used. About 22 Brix-26 Brix is suitable as a sugar suitable for preparing persimmon fruit wine. More preferably, it is adjusted to about 24 Brix.

Step 3: Sterilize

Persimmon juice added with the Schisandra chinensis and the sugar of the second step can be carried out alcohol fermentation without undergoing sterilization process. However, in order to perform safer fermentation without contamination of various germs, sterilization is carried out at 60 to 70 ° C for 30 minutes. Sterilization conditions may vary depending on the degree of contamination of the sweet persimmon juice.

Fourth Step: Inoculation of Yeast and Alcohol Fermentation

After cooling the persimmon juice sterilized in the third step to room temperature (about 25 ℃) and inoculated about 2.5% by volume ratio with respect to the persimmon juice prepared in advance and 10 to 14 days, preferably 25 at 20-30 ℃ Alcohol fermentation is carried out for 12 days at < RTI ID = 0.0 >

The fermented yeast is not particularly limited, and a conventional kind of yeast used for producing fruit wine can be used. For example, yeasts of the genus Saccharomyces such as Saccharo myces cerevisiae can be used. In one embodiment of the present invention, Saccharomyces cerevisiae ( KCCM 12650) , which is mainly used as a wine fermentation yeast, was used.

When the fermentation is completed by the above method, the sediment deposited in the fermenter and the suspended matter in the liquid level may be further separated and filtered according to a conventional method. Filtration can be performed by centrifugation or using a membrane filter. In addition, the obtained filtrate may be further subjected to low temperature aging 7-10 days at 4-8 ℃.

The method for preparing persimmon fruit wine according to the present invention is characterized in that the fermentation is smoothly achieved by lowering the pH of the initial fermentation by adding Schisandra chinensis to persimmon juice obtained by high efficiency by crushing and juice the persimmon with a centrifugal juicer. Persimmon fruit wine produced according to the method of the invention has a characteristic that the quality is very excellent by improving the sensory characteristics such as moderate taste and aroma and color (see Experimental Example 2 and Experimental Example 3).

Hereinafter, the present invention will be described in more detail with reference to the following examples. However, these examples are intended to illustrate the present invention in more detail, and the scope of the present invention is not limited to these examples.
