Abstract

PURPOSE: Provided is a method for preparation of alcoholic liquors which is abundant in mineral and tastes clean and soft, by characteristically using bamboo charcoal as a deodorant. CONSTITUTION: The method for preparation of alcoholic liquors is characterized by adding additives to undiluted liquor then blending them; diluting the mixture with a solution for making liquor; and deodorizing it with a deodorant then filtering it, wherein bamboo charcoal of 0.001-0.05%(w/v) is used as a deodorant.

Description

Production method of liquor using bamboo charcoal {PROCESS FOR PREPARING ALCOHOLIC LIQUORS USING BAMBOO COAL}

The present invention relates to a process for producing liquor that is free of flavours, has a smooth taste and is rich in minerals.

Conventional liquor manufacturing method is to add the additives to the liquor stock solution, blended, diluted with casting water, and then deodorized and filtered with a deodorant, activated carbon is used as a deodorant, the flavor of the liquor is left unsweetened taste there was.

Recently, Japan's Suntory manufactures whiskeys by passing the undiluted whiskey through the bamboo charcoal tower and filtering it. However, this method not only removes trace components related to the aroma, taste, and color of the stock solution by passing the whiskey solution directly through the bamboo charcoal tower, but also requires an expensive new bamboo charcoal tower device. The bamboo charcoal tower does not have constant filtration effect and ion elution concentration over time, so the whiskey liquor is not filtered uniformly, and the bamboo charcoal needs to be replaced periodically and requires a separate bamboo charcoal washing process. There are disadvantages not suitable for production.

Accordingly, the present inventors have directly introduced bamboo charcoal without using an expensive bamboo charcoal pagoda to develop liquor that is free of odor, has a soft taste, and is rich in minerals.

It is an object of the present invention to provide a process for the production of liquor, which is free of odor, has a smooth taste and is rich in minerals.

1 is a diagram schematically showing a post-deodorization process using bamboo charcoal according to the present invention.

According to the above object, in the present invention, the additive is added to the liquor stock solution, blended, diluted with casting water, deodorized with a deodorant and filtered to produce liquor, wherein the deodorant is bamboo charcoal, characterized in that bamboo charcoal (竹炭) To provide.

Hereinafter, the method of the present invention will be described in more detail.

The method of the present invention is characterized by using bamboo charcoal instead of the conventional activated carbon as a deodorant used in the deodorization process in the production of liquor (FIG. 1), and the liquor to which the method is applied is distilled soju, distilled soju, whiskey. , Brandy, ginseng wine and the like are preferable.

Bamboo charcoal used as a deodorant in the present invention is bamboo charcoal, has twice as many micropores as ordinary charcoal, and thus has a large surface area of 200 to 300 m 2 per 1 g of bamboo charcoal. Bamboo charcoal not only adsorbs odorous gases such as hydrogen sulfide, impurities such as chlorine and trihalomethane in heavy metals and tap water, but also has properties such as elution of mineral components, far-infrared radiation, anion emission and electromagnetic shielding in aqueous solution. It can be used for various purposes in addition to deodorant.

Representative examples of bamboo charcoal may include, but are not limited to, Bongjong bamboo charcoal, royal bamboo charcoal, and cotton bamboo bamboo charcoal. Mengjong bamboo charcoal (孟宗竹 炭) is known to have a higher ionic content than other bamboo charcoal, double cations include calcium, potassium and ammonium ions beneficial to the human body and ions, chlorine, phosphoric acid and sulfate ions. In addition, since anions are present in a small amount, they are suitable for drinking water quality standards, and are harmless to humans.

In addition, the bamboo charcoal may be in the form of powder, granular form or raw coal, of which powder is preferable. Bamboo charcoal may be used in an amount of 0.001 to 0.05% (w / v) relative to the liquor stock.

The bamboo charcoal removes unpleasant odors and impurities in the liquor stock solution, and at the same time, the mineral component is eluted from the bamboo charcoal to obtain a mineral-rich liquor.

Hereinafter, the method of the present invention will be described in more detail.

First, an additive is added to the liquor stock solution and blended (blending step). The liquor stock solution refers to the liquor before the additive material is added. Specifically, distilled liquor liquor is diluted with distilled liquor at 95% alcohol concentration to 45% alcohol concentration with casting water and then deodorized with activated carbon and filtered. Alcohol may be used, and as the liquor stock solution of distilled soju, a product obtained by refining a mature stock solution of distilled soju using activated carbon or an ion exchange resin may be used. In addition, the additives include steviosides, sugars, high fructose, oligosaccharides, citric acid, glycine and salts which are commonly used, and may be used in an amount of 2% (w / v) or less.

To this, casting water is added and diluted appropriately (water process). The casting water may be water commonly used to dilute the liquor stock solution. The dilution concentration can vary according to the liquor desired, which is 25% in the case of regular soju.

Add 0.001 to 0.05% (w / v) of bamboo charcoal to the liquor stock diluted appropriately to the desired alcohol concentration, stir for 30 minutes to 3 hours, deodorize, filter through diatomaceous earth (deodorization and filtration process) (Bottling process)

Taking the dilute shochu as an example, the method of the present invention will be described.

The method of the present invention has the advantage of introducing the deodorization of the bamboo charcoal and the adsorption of impurities and the elution of ions into the liquor while being applied as it is to the currently used liquor manufacturing process without changing the process.

Hereinafter, the present invention will be described in detail by way of examples, but the present invention is not limited thereto.

Reference Example 1: Dissolution test of bamboo charcoal in water and alcohol aqueous solution

To analyze the ions eluting from bamboo charcoal in water or an aqueous alcohol solution, the bamboo charcoal (Jiri Bambu Hi-Tech Co., Ltd. or Yangil Unemployed Product) was pulverized to 100 mesh or less and then 1% (w / w) in pure water or 60% alcohol solution. v) was added at a concentration and stirred for 3 hours and then filtered through a filter paper with a pore size of 0.8 μm. Ions in the filtrate were analyzed by inductively coupled plasma spectrophotometer (ICP).
