Description

Beer made using potatoes

The present invention relates to beer using potatoes, and more particularly, to beer using potatoes that can replace expensive malt.

Beer is a low-alcohol beverage, which accounts for the largest proportion of global alcoholic beverage consumption.

In general, beer is made with malt, water, hops, and yeast as main ingredients. Malt is produced by germinating barley or wheat, saccharified by the malt's own enzymes, hops are added to the saccharification solution, boiled, and then yeast is added to produce malt through the alcohol fermentation process by yeast that occurs under anaerobic conditions. the usual way.

Among them, malt is an essential raw material for beer. However, as the price of imported malt fell after the Free Trade Agreement (FTA), the competitiveness of domestic malt became very low, and the cultivated area and production continued to decrease. . Accordingly, the present inventors replaced some of the malt with domestic potatoes to produce beer that can localize raw materials and replace expensive malt.

Potato ( Solanum tuberosum ) is native to the Andes Mountains, and is a dicotyledonous perennial plant of the Solanaceae family. A plant that forms tubers, usually using the tubers. The components of tubers are 75-80% water, 15-20% carbohydrates, 2% protein, and 0.1% fat. In addition, it contains various vitamins such as ascorbic acid, thiamin, pyridoxine, and rioboflavin. In particular, ascorbic acid contains about 5 to 25 mg per 100 g, so it has an effect of preventing oxidative stress caused by ROS. In addition, it is an important source of lysine among proteins, and it can be said that it is a crop with various nutritional values because it contains inorganic components such as iron and potassium.

Recently, as the craft beer market grows, research on beer using various raw materials is continuously increasing. Looking at the related technologies developed in the past, “Red Garlic Beer and its Manufacturing Method” (Application No. '10-2009- 0011410'), “Method for manufacturing beer using university wax corn and beer manufactured by the method” (Application No. '10-2015-0028188'), “Germained brown rice beer and manufacturing method thereof” (Application No. '10-2008 -0040754') and “Method for manufacturing Audi beer” (application number '10-2017-0158393'), but there is no beer made from potatoes.

Accordingly, an object of the present invention is to provide a method for producing beer using potatoes, which has the functionality of potatoes, has a taste and aroma similar to that of existing beer, and has a characteristic, and is helpful in increasing the income of potato farmers and creating jobs.

On the other hand, the problems to be solved by the present invention are not limited to the problems mentioned above, and other problems not mentioned will be clearly understood by those skilled in the art from the following description.

According to one embodiment of the present invention in order to achieve the object of the present invention as described above, there is provided a beer prepared using potatoes prepared by saccharifying dried potato.

In this case, the dried potato, ground malt, saccharification enzyme and pH adjusting agent may be boiled in water for brewing, and may be beer prepared using potatoes.

The dried potato may be dried in the form of flakes after thinly sliced boiled potatoes.

The weight ratio of the dried potato and ground malt may be 3:7 to 7:3.

The glycosylation enzyme may be an enzyme that degrades glucan and hemicellulose.

The pH adjusting agent may be at least one of calcium chloride and calcium sulfate.

The glycosylation enzyme may be at least one of α-amylase, β-amylase, gluco-amylase, and beta-glucanase.

The beer prepared by using the potato of the present invention has the advantage that the potato can be pre-treated and mixed with malt, and the starch of the potato can be decomposed into sugar required for beer, so that it can be used as sugar instead of expensive malt.

In addition, from a nutritional point of view, there is an effect of ingesting essential and micronutrient active ingredients such as ascorbic acid, iron, and potassium extracted from potatoes.

In addition, it is possible to provide beer with a unique deep taste and a different odor, and by proposing a new use of potatoes, it is possible to provide the effect of increasing the income of potato farmers by promoting potato consumption.

Effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned may be clearly understood by those skilled in the art from the following description.

1 is a flowchart of a beer manufacturing method using potatoes according to an embodiment of the present invention.

Hereinafter, the present invention will be described in detail. Prior to this, the terms or words used in the present specification and claims are not to be construed as being limited to conventional meanings, and the inventor must properly explain the concept of the term in order to best describe his invention. Based on the principle that it can be defined, it should be interpreted as meaning and concept consistent with the technical idea of the present invention. Accordingly, the configurations described in the embodiments described in this specification are only the most preferred embodiment of the present invention, and do not represent all the technical spirit of the present invention, so various equivalents that can be substituted for them at the time of the present application It should be understood that there may be variations and variations.

1 is a flowchart of a beer manufacturing method using potatoes according to an embodiment of the present invention.

The present invention provides beer prepared by using potatoes prepared by saccharifying dried potato. More specifically, it may be a beer prepared including the potato pretreatment step (S10), the saccharification step (S20), the boiling step (S30), the precipitation step (S40), the fermentation step (S50), and the aging step (S60). .

The potato pretreatment step (S10) is a step of obtaining dried potatoes by thinly flattening the boiled potatoes and drying them. More specifically, the potatoes are peeled and boiled, spread thinly using a roller, and dried in a dryer to form flakes. This is a step to obtain a thermally dried product.

The present inventors confirmed that potato is the most similar variety to malt through organic sugar analysis. On the other hand, potatoes that can be used as food applicable to the present invention can be used without limitation, such as colored potatoes, regardless of the variety, and preferably, potatoes produced in Gangwon-do, Republic of Korea can be used.

At this time, by drying the potato in the form of flakes, it is easy to manage and has the effect of increasing the saccharification efficiency.

In addition, when potatoes are cooked and dried, there is an effect of improving fermentation ability and simplifying the process through pretreatment processes such as pressurization, steaming, starching, and pressing, etc. There is this.

The saccharification step (S20) is a step of adding dried potato, pulverized malt, saccharifying enzyme and a pH adjuster to brewing water and boiling to obtain wort, more specifically pulverizing malt, and adding ground malt to brewing water, dried potato, It is a step of boiling by adding an enzyme (visco-buster) for decomposing 1-3,1-4-glucan for efficient sugar extraction and decomposition of hemicellulose such as xylan and arabinoxylan. .

Beer is made by ingesting grain sugars by yeast and releasing alcohol and carbon dioxide. At this time, the yeast does not have the ability to digest the starch in the grain, so a saccharification step is needed to convert it into sugar. On the other hand, the present invention replaces malt baked by applying heat after sprouting of barley, and uses a potato heat-dried product containing a large amount of starch that can be converted into sugar, thereby improving the beer brewing process. Alcoholic fermentation, which is the key, is achieving the effect that more can occur.

On the other hand, enzymes are macromolecular proteins that help chemical reactions and play a major role in changing substances in the beer manufacturing process. More specifically, the starch in the crushed malt and dried potato is decomposed into simple sugars by the action of the enzyme, which is in a state that yeast can consume. Therefore, the present inventors have found that, through numerous repetitions, enzymes (visco-buster) for decomposing 1-3,1-4-glucan and hemicellulose such as xylan and arabinoxylan are potato It was confirmed that the efficiency of decomposing starch mixed with dry matter and malt into simple sugars was the best, and more specifically, α-amylase, β-amylase, gluco-amylase, beta-glucanase, and protease 1 It was confirmed that, when more than one type of mixture was used, the potato starch could be efficiently converted into a sugar component capable of alcoholic fermentation and at the same time, effects such as improved filterability could be achieved.

On the other hand, the pH adjusting agent of the present invention is to add a mineral to create a suitable pH for the enzyme to act. As a preferred example, calcium chloride and calcium sulfate may be used alone or in combination.

In addition, the weight ratio of the dried potato and the pulverized malt in the saccharification step may be 3:7 to 7:3, and if the above range is satisfied, it is the same as beer using only imported malt while using domestic potatoes as a substitute for expensive imported malt. Alternatively, a beer with a better flavor may be provided.

Corn and rice, which have been sought as substitutes or sub-materials for malt, have a low protein ratio to malt, which can act as a factor in reducing foam retention. It can be said that there are fewer things to consider when replacing.

In addition, since potatoes, which have a protein content of 2% higher than malt, are used in a ratio of about 30% of the whole dried potato and ground malt, it can have better foam retention compared to beer with 100% malt.

In addition, protein also affects the degree of hazyness of beer. Potatoes contain about 2% higher protein than malt, so there is not much difference in appearance, so the color or turbidity of beer that consumers think is Beer that meets the standards can be manufactured.

The boiling step (S30) is a step of boiling by adding hops to the wort, and more specifically, filtering the wort obtained after saccharification and boiling with hops, coriander seeds, and orange peel.

The precipitation step (S40) is a step of precipitating and removing the coagulated material of the boiled wort, and more specifically, a step of removing the precipitated material by precipitating the hops and coagulated material contained in the boiled wort.

The fermentation step (S50) is a step of cooling the wort from which the coagulation is removed, and then performing alcoholic fermentation by adding yeast.

On the other hand, the aging step (S60) is a step of aging the fermented wort, and more specifically, it is a step of transferring and aging the contents from which the orange peel is removed during the post-fermentation.

Hereinafter, the present invention will be described in more detail through Examples, but it is clear that the present invention is not limited by the Examples.

Example 1

Therefore, it was confirmed that potato beer prepared according to an embodiment of the present invention is enjoyed and preferred by not only Korean adults but also foreigners.

Recently, as the number of consumers in their 20s and 30s who value trends in domestic beer consumption increases, the public's interest in craft beer is increasing. In addition, as the liquor tax law was revised from an ad valorem tax to a specific tax, the growth rate of the craft beer market is increasing every year. In line with this, various craft beers are being developed in Korea. In the present invention, by using potatoes, which were not used as raw materials for beer, a new direction is suggested, and by substituting some malt, the cost can be lowered, thereby increasing price competitiveness and having market competitiveness. In addition, by using potatoes from Gangwon-do, which accounts for more than 30% of potato production, it will be able to establish itself as a brand with a distinctive image and regional character.

Potatoes used in the present invention can be used in various beer styles such as IPA, Lager, Pale ale, and other alcoholic beverages such as whiskey, as well as the above-mentioned manufacturing method. Therefore, it is possible to increase the income of potato farmers through contract cultivation with farmers by proposing various new uses for potatoes. In the distribution, not only contract distribution through antenna stores and liquor wholesalers, but also Internet mail-order sales of liquors are recently allowed, enabling us to open up various markets where we can secure online communication networks. will be able
