Description

Technical Field [0001] The present invention relates to a coffee bean germination method using a magnetized active water,

More particularly, the present invention relates to a process for germinating coffee beans using magnetized water. More specifically, the present invention relates to a method for germinating coffee beans using a magnetized water, The present invention relates to a method of germinating coffee beans that can maintain the moisture, temperature, and pH of a bean after washing and then immersing it in an optimum state, thereby shortening the germination time of the coffee beans and increasing the germination rate.

Coffee trees bloom after about two years of planting, and about three years later they form a cherry of red or yellow. The seeds that have peeled off the outer skin, pulp, parchment, and silver skin from coffee berry are called green beans.

There are three varieties of coffee produced worldwide: Arabica, Robusta, and Liberica. Today, Arabica and Robusta are 70% and 25%, respectively, accounting for 95% of the total production. Worldwide coffee is produced in the tropical and subtropical region between 25 and 25 ° N, which is called a coffee belt or coffee zone.

Coffee is mostly produced in Latin America, the Middle East, Africa, the Pacific, and Indonesia. Coffee is an important part of the world economy and about 7 million tons are produced, of which 5.2 million tons are exported from the mountains to foreign countries. The world coffee consumption is between 6 million and 6.5 million tons, and the world person consumes 1 kg (about 100 remainder) of coffee per person per year.

 The process of separating and refining seed bean, which is a seed in coffee bean, is an important processing process that determines the quality of bean curd. It is a dry method in which harvested cherries are dried as it is, (Wet method). Imported green beans are known to be effective for roasting, grinding, and coffee extraction to make coffee beverages after having been subjected to such purification process and then dried to maintain the moisture content at about 12%. After the refining, dried green beans are stored in wrapping paper. Imported green beans are usually harvested more than one year after harvest. They are largely dependent on the above-mentioned dry and wet methods, and germination is difficult. For coffee tree breeding, hat coffee within 6 months is germinated well. Usually, only the pulp is removed, and the spermatogonium and hippopotamus are sowed in the state.

Therefore, it is very difficult for imported coffee to germinate in a state in which these inner and outer hippocampus are partially removed. It is believed that silkworm, during storage, contributes to the prevention of access to fungus from outside and to maintaining humidity inside the green bean. It is generally known that it takes 4 to 6 weeks before germination of old coffee beans usually depends on factors such as germination temperature and humidity.

During germination, germinated coffee is activated by the dormant enzyme in the coffee beans, so that various amino acids are distributed in a balanced manner compared to the germination, the caffeine content is reduced, the moisture is swollen in the germination during germination and some impurities Or foreign matter such as fungi can be easily separated and removed in the course of washing. Therefore, it has been reported in the patent literature that coffee beans can be made with clean germinated coffee and improved in coffee aroma, taste and texture, -1031142, and 10-2011-003407)

Due to the importance of germinated coffee with these advantages, patent applications for the method of manufacturing germinated coffee in domestic are continuously increasing. Even if optimum germination conditions are maintained by adjusting temperature, humidity, etc. of coffee bean sprouts, germs such as staphylococci are easily propagated during germination, so that germinated coffee of good quality can not be produced. Recently, many patents have been filed or registered with a focus on germinated coffee manufacturing methods to shorten germination period.

For example, the above-mentioned Patent Registration No. 10-1031142 and Patent Document No. 10-2011-003407 disclose a method in which coffee beans are firstly dipped in alkaline hot water (about 2 to 4 hours) and the temperature of the hot water is maintained at 15 to 40 ° C Next, the absorbed coffee bean separated from the hot water was sprayed with hot water over the green bean through the nozzle while contacting with the air. It is preferable to set the temperature of the humidified atmosphere to 37 ° C or higher and the upper temperature to 80 ° C or so. However, the optimum temperature is not specified, and germination starts in about 3 hours in a wet atmosphere. It is reported that germinated coffee beans can be prepared in 8 to 8 hours.

Korean Patent Laid-Open Publication No. 10-2011-0031299 discloses a method for producing a germicidal composition, which uses germicidal active water through a magnetization activated water generator instead of alkaline (pH 10 to 11) And a shower capable of sprinkling hot water from the upper part of the germicidal container is provided, and a device capable of germinating under a wet atmosphere without a separate immersion step is proposed. GABA (Gamma-Amino Butyric Acid), which is a physiologically active substance, is remarkably increased during germination. However, there is no practical data or analysis data. In addition, there is no mention of the wetting temperature and germination time necessary for the germination condition.

Korean Patent Registration No. 10-1041865 discloses a method for manufacturing a beverage, which comprises washing a coffee bean with high pressure at a pressure of 100 to 120 bar to remove foreign matter, and immersing the magnetized water having magnetized pure water not containing minerals in the germ of a pottery And continuously supplying oxygen through the impeller at a temperature of 20 to 40 ° C for 4 to 8 hours. However, even with high pressure washing, there is a limit to clean the fresh and dead skin with the skin and endothelium adhered to the surface.

The methods of manufacturing germinated coffee as shown in the above patents have made great progress in shortening germination time to about 4 to 8 hours, but germination rate is the most important in view of economical efficiency. The germination time and the germination rate can be improved to some extent by using pure water which has been subjected to the magnetization treatment without the alkaline hot water, magnetization active water and minerals. However, the germination rate and germination time can be significantly different depending on the storage conditions such as the location, humidity, temperature, Especially, the difference between the harvested hat coffee harvested in that year and the old one is much bigger. It is very important to prevent microbial contamination on the surface of the seedling during germination, to clean it, and then to enter the germination stage.

Therefore, there is an urgent need to develop a germination method and a germicidal method which can be applied to old coffee beans which are believed to be one or two years old from the production of Arabica coffee soybeans and Robusta green beans. In addition, since germinated coffee is only 1 to 2 mm long and is very thin and weak, it is difficult to distinguish between germinated coffee and germinated coffee because the germination can take place in the process of circulating or watering the hot water by the pump, There is a real problem that is difficult to measure.

Accordingly, the present inventors have studied a method for shortening the germination time and increasing the germination rate of coffee bean sprouts, and have found that, when magnetized water is produced by simultaneously treating magnetic water and far-infrared rays in general water, The coffee green beans were washed at room temperature and then immersed and then germinated at a temperature of 55 to 65 ° C for 2 to 4 hours at a pH of 4 to 8 to obtain a 1 to 2 year old coffee The present invention has been accomplished by confirming that germinated coffee beans can be produced economically in a short period of time by using the coffee bean germination method of the present invention because the germination percentage of green beans is 80% or more.

The object of the present invention is to provide a method for producing magnetized water by simultaneously processing magnetic force and far-infrared rays in general water, and then washing the coffee green bean with the magnetizing active water at room temperature, The present invention relates to a method for germinating coffee beans, which can shorten the germination time of coffee beans by maintaining the temperature and the pH at optimum levels, and can remarkably increase the germination rate.

In order to achieve the above object,

1) magnetizing water to produce magnetized water;

2) first washing the coffee bean with the magnetically active water of step 1), transferring it to the germination water bath, and germinating at 40 to 70 ° C for 2 to 5 hours; And

3) Secondly washing the germinated coffee beans with a minimum amount of magnetizing active water and then dehydrating the coffee beans.

In addition, the present invention provides germinated coffee prepared by the method of the present invention.

The coffee bean germination method using the magnetization activated water of the present invention is a method of germinating coffee beans by preparing a magnetized water by treating magnetic powders and far infrared rays at the same time with general water and then adding a coffee green bean to the magnetized water at room temperature By maintaining the moisture, temperature and pH at the optimum state after the first washing and immersion in the germinated water tank, the germination time of the coffee beans is effectively shortened and the germination rate is remarkably increased as compared with the germination method of the existing coffee beans , The germination method of the present invention can be usefully used to produce economically clean germinated coffee in a short period of time.

[ (150). The germination water tank 110 is formed in a cylindrical or cubic shape having an open upper surface and has a foldable first tongue 11a capable of receiving a seed receptacle 50 to be germinated on its inner wall, And a foldable second step 11b capable of receiving the part. Here, the upper and lower surfaces of the germinated seedling receptacle 50 are formed so that water can pass through but not through germination, and the number of the germination receptive receptacles 50 is composed of a plurality of germination receptacle 50 . In addition, the germinated seeds can be removed by the load, so that they can be laminated as thin as possible. The number of the first jaws 11a may be changed according to the number of the raw material receptacles 50 accommodated in the germination water tank 110. A hole 11 for discharging the magnetizing active water contained in the germination water tank 110 is formed on the surface of the second step 11b. In addition, a discharge port connected to the discharge valve (V5) is provided on a lower side wall of the germination water tank (110) to discharge the magnetizing water in the germination water tank when the germination water tank is washed . The first magnetizing active water supply unit 120 varies the tap water or ground water supplied through the water supply pipe connected to the upper portion of the germination water tank 110 to magnetization active water and supplies the magnetization activated water to the germination water tank.

More specifically, the first magnetizing active water supply unit 120 is connected to a supply pipe connected to the two valves V1 and V2. The supply pipe is a pipe for supplying tap water or ground water. The first valve V1 and the second valve The tap water or the ground water can be selected through the opening and closing operation of the two-valve V2 (FIG. 1).

< Example  2> Coffee Green bean  Germination process

The germination process, the washing process, the dehydration process and the drying process of the coffee beans were sequentially carried out using the coffee bean germination apparatus manufactured in Example 1 above.

Specifically, as shown in Fig. 2, in the germination process of coffee bean sprouts, a germination container charged with green beans is immersed in a germination water tank as a dipping method, and then the magnetization activated water subjected to primary magnetization treatment of tap water is supplied into a water tank, The water level was adjusted so as to be sufficiently locked. Then, the time was set so that the electric heater could be operated and the germination temperature could be maintained at a suitable temperature of 60 캜 for 4 hours.

In the cleaning process, after the germination process is completed, the operation of the electric heater is stopped, and then the water is discharged through a drain hole under the germination tank. Then, after closing the drain valve, the first activated magnetization water at room temperature was supplied, filled in the same manner as in the germination process, and then discharged again through the drainage port, and the foreign substances remaining in the coffee were removed three times. Also, in order to prevent desorption of coffee beans and sprouts during drainage, the drainage rate was adjusted with proper control.

In the dehydration process, the air was blown down from the germination vessel through the air shower from the upper part of the germination tank after the washing process, and the water was removed. In order to prevent desorption of the coffee beans, I raised the water.

After the dewatering process was completed, the drying process was transferred to a dryer and dried by blowing air at a low temperature so as to have a moisture content of 12% (FIG. 2).

< Experimental Example  1> Magnetization active number  Confirm the effectiveness of manufacturing equipment

In order to confirm the effect of the magnetized water producing apparatus manufactured in Example 1, tap water was passed through the magnetized water producing apparatus manufactured by the present invention at atmospheric pressure, and oxygen was measured by INOVA-500 Varian-NMR -17 nuclear magnetic resonance O-17 NMR spectrum was measured.

Specifically, the measurement temperature was set to 25 ° C, and the half width corresponding to half of the height of the spectrum known to decrease the cluster of water as the linewidth became narrower was expressed in Hz.

As a result, it was confirmed that the half-value line width of the O-17 NMR spectrum of the tap water was 140.62 as a control group as shown in Fig. 3A, and as shown in Fig. 3B, water was passed through the O- The half-value linewidth of the 17 NMR spectrum was 101.69, which was reduced by 38.53 as compared with the control group, confirming that the clusters of water passed through the apparatus for producing magnetized water of the present invention became smaller. Further, as shown in FIG. 3C, the half-value line width of the O-17 NMR spectrum after passing the water springs through the apparatus was 94.99, which was found to be 45.63 less than tap water (FIG. 3).

< Experimental Example  2> Confirm cleansing power of magnetizing activated water

The tap water was once passed through the apparatus for producing magnetized activated water prepared in Example 1, and the washing water according to the change of the amount of detergent was sent to the KATRI washing and washing machine research center (Seoul) Respectively.

Washing force (%) = (Washing degree after washing - Washing degree before washing) / (Washing degree before washing - Washing degree before washing) X 100.

As a result, as shown in Table 1 and Fig. 4, when the washing power of Sample 1 into which 60 g of detergent was added was 100, the amount of washing detergent was reduced by 1/2 or 1/4, 94.9%, 72.3% and 55.6%, respectively. The detergent was reduced by about half of the standard amount, and the cleaning efficiency was reduced by about 5%. Therefore, it was confirmed that the cleaning power of the magnetically activated water was higher than that of ordinary tap water, and it was confirmed that foreign matter can effectively be removed using the magnetization activated water in the cleaning process after the germination process of coffee green beans (see Tables 1 and 4 ).

< Experimental Example  3> Coffee Green bean  Germination rate confirmation

The germination rate of the coffee beans was confirmed using the coffee bean germination apparatus manufactured in Example 1 above.

Specifically, the germination temperature and the germination rate of the coffee bean germinated with the kenya AA (Kenya) in Arabica were determined. It is estimated that the Kenya AA is produced when it is imported and it is 2 years since it was produced. The germination water tank of the apparatus manufactured in Example 1 was minimized, that is, the size of one magnetized water producing apparatus in the water tank was used, and the water was tap water activated. The germination rate and germination rate were measured using 100 seedlings in one experiment. The germination time was calculated based on the point of time when the temperature was reached.

As a result, as shown in Table 2 and FIG. 5, it was confirmed that the germination rate also increased as the germination bath temperature increased. Germination was slow progression at 50 ℃ or below and germination rate after that increased 53% at 55 ℃ and 50% at 60 ℃ for 2 hours. The germination rate was 56% at 2 hours and 82% at 4 hours at 65 ℃ or higher. Therefore, it was confirmed that the optimum germination condition was 60 캜 and the time was 4 hours, which showed an effective germination rate in a short time as compared with the results of the patent documents published so far (Table 2 and Fig. 5).
