Description

The manufacturing method of coffee liqueur {Method of manufacturing liquor containing coffee}

The present invention relates to a method for producing a liqueur (alcohol) to which the unique taste and aroma of coffee are added.

In general, alcohol has been used as a favorite food that has been with human history, as a food for events before, and recently as a beverage to find and drink according to individual tastes.

As a functional alcoholic beverage, there is a fruit wine made by naturally fermenting fruits such as grapes, apples, plums, and pears, or by extracting the components (taste and aroma) of fruits by adding fruit and sugar to original wine such as soju. .

However, most fruit wines are inappropriate to drink due to their strong acidity and bitterness caused by a large amount of organic acids, and it is true that some sugars are excluded from drinkers who do not like sweet taste. In addition, it has a harsh scent, has an unclean taste, and has a high hangover, so it is not used favorably by various age groups. Accordingly, development of alcoholic beverages using new raw materials other than fruit wine is required.

Coffee is a bitter and sour drink made by roasting the seeds (coffee beans) of the coffee tree and brewing it with warm water or steam.

There have been attempts to apply such coffee to various products such as alcohol in addition to beverages.

Coffee liquor is generally prepared by alcohol fermentation using grain sugar raw materials such as rice, yeast and coffee, or by immersing alcohol in coffee beans or coffee extract.

However, the coffee liquor produced in this way has a strong astringent taste and bitter taste derived from the raw material, the balance and harmony of smell and taste are bad, the freshness is poor, the deep smell is insufficient, and coffee deposits are generated.

The present invention is to solve the above problems, and to provide a manufacturing method that allows the unique taste and flavor of coffee to be expressed in a balanced and harmonious manner in alcohol.

In order to solve the above problems, the present invention comprises the steps of preparing steamed rice by steaming non-glutinous rice; preparing a coffee liquid by adding purified water to roasted coffee beans, adding glucose, tartaric acid, and diammonium phosphate and stirring to dissolve them uniformly; Mixing the entry, yeast, lactic acid and purified water and fermenting it for 4 to 5 days at 22 ~ 25 ℃ to prepare a base wine; preparing the first stage immersion by adding entry and water supply to the base wine and fermenting it at 22 to 25° C. for 3 to 4 days; preparing the second-stage soaking by adding the steamed rice, puffed rice, purified enzyme and water to the first-stage soaking and fermenting it for 3-5 days at a temperature of 25 to 27°C; A post-fermentation step of putting the coffee liquid and water in the second-stage immersion, post-fermenting at a temperature of 25 to 27° C., and then rapidly cooling to room temperature; Forming step of removing alcohol lees from the post-fermented fermented product and adding acesulfame potassium, citric acid, coffee flavor and drinking water to adjust the alcohol content to a predetermined alcohol content; and a commercialization step of sterilizing and packaging the alcohol; provides a method for producing a coffee liqueur comprising.

According to the present invention, in the process of producing alcohol by fermentation, a roasted coffee powder solution with added sugar is added and post-fermented, thereby strongly expressing the characteristic savory odor of roasted coffee in the final product, alcohol, and alcohol and coffee by post-fermentation. It becomes possible to show a balanced taste while harmonizing the taste, and to strengthen the flavor, and by not using hot water extracted coffee liquid, the acidity is maintained and the occurrence of precipitation is reduced.

The manufacturing method of alcohol is made by using koji and yeast to make malt wine, and mixing yeast, steamed rice, puffed rice, and water as ingredients for deotsul to the malt wine and fermenting it for 3 to 9 days.

The present invention is a method for producing a coffee liqueur with improved palatability by adding coffee liquid to the alcohol produced by fermentation during the alcohol production process and post-fermenting it.

Coffee, when the coffee tree fruit is ripened red, the flesh opens and green coffee beans are produced, which are dried and roasted to produce coffee beans. You can drink it by dissolving it in the water, or extracting the roasted coffee bean powder directly with water and enjoy it as a coffee bean beverage.

The taste is various, such as bitter, sour, sweet, and astringent. The bitter taste comes from caffeine, the bitter taste comes from tannins, the sweet taste comes from sugar, and the sour taste comes from fatty acids. It is linoleic acid, and it contains moisture, crude protein, crude fiber, ash and volatile organic acids that give flavor.

As a stimulant, coffee acts on the nervous system to stimulate mental activity and perception to make thinking more clear, physically straining muscles to increase labor power, and helping diuresis to promote gastrointestinal activity and sleep. It has been reported to be effective in chasing arousal effect, improving learning ability, dieting, enhancing exercise ability, preventing and relieving hangover, and inhibiting arteriosclerosis.

In particular, the magnesium component in coffee helps to suppress diabetes, and the chlorogenic acid component, as a kind of polyphenol compound, has the effects of inhibiting the production of lipid peroxide in the living body, inhibiting cholesterol biosynthesis, antioxidant action and anticancer action. perform

In the present invention, in using roasted coffee powder in order to express the characteristic savory odor of coffee and to reduce the astringent taste caused by the inclusion of coffee, a powder of sodium ascorbate is mixed within 1 day after green coffee beans are roasted. A coffee liquid prepared by grinding to obtain a roasted coffee mixed powder, adding purified water to the roasted coffee mixed powder within one day of grinding, adding glucose, tartaric acid, and diammonium phosphate and stirring to uniformly dissolve it can be used.

Coffee is made by extracting hot water, and the coffee thus made deteriorates over time, and the original smell and taste of coffee deteriorate and flavor is impaired. The roasted coffee powder mixed with sodium ascorbate is ground By using it inside, astringency is suppressed and coffee liquor with a good finish can be produced.

In addition, by adding sugar to a solution containing coffee and performing alcohol post-fermentation to be described later, coffee liquor with a rich flavor and coffee taste that is richly expressed by roasting coffee beans can be made.

At this time, the content of roasted coffee powder added for post-fermentation is preferably 0.01 to 20 w/v%. Doing so may cause burnt smell and bad taste.

In the present invention, polyphenol-based useful components contained in coffee beans are not destroyed by heating at high temperature by not performing high-temperature treatment such as hot water extraction. A lot of useful components of coffee beans are eluted by aging with alcohol components at low temperature for a long time, but even sediments are eluted, and these components deteriorate the storability and aesthetics of alcohol.

Calcium may be added during post-fermentation in order to further elute useful components of coffee beans during the manufacturing process, and it is preferable to add 3-7 parts by weight of calcium based on 100 parts by weight of coffee bean powder.

Propylene glycol may be added during post-fermentation in order to further elute useful components of coffee beans, and it is preferable to mix 5 to 10 parts by weight of propylene glycol based on 100 parts by weight of coffee bean powder.

Propylene glycol is widely used as a solvent for dissolving pigments, essential oils, resins, etc. and mixing them with water and has emulsion stability, so it elutes polysaccharides, lipids, organic amino acids, proteins, minerals, etc. During post-fermentation, both water-soluble and water-insoluble useful ingredients of coffee can be contained, and the emulsion stabilization performance of propylene glycol prevents coffee particles from precipitating during storage of coffee-containing alcohol. can improve the marketability of

Green coffee beans generate a volatile aroma during the roasting process to create a unique coffee flavor, and also brown polymer melanoidin by the Maillard reaction between the carbonyl group and amino group of the protein contained in green coffee beans. A non-enzymatic browning reaction that produces (melanoidine) occurs, and the coffee aroma produced enhances the flavor of alcohol.

The post-fermentation can be carried out until the gas pressure reaches a pressure of 1.2 to 1.7 kgf/cm 2 by the post-fermentation by adding and mixing the solution containing the coffee to the liquor made of the fermentation and aging for a predetermined period. .

By fermenting coffee beans based on alcohol, the unique flavor of coffee can be strengthened and the flavor due to the generation of carbon dioxide can be improved.

After the post-fermentation, as a preparation step, alcohol lees are removed, acesulfame potassium, citric acid, coffee flavor, and drinking water are added to prepare alcohol adjusted to a predetermined alcohol content, sterilize, and package to manufacture coffee alcohol.
