Example Embodiment

[0040] Example 1.

[0041] 300g of koji was added to 1000g of hard rice made of rice and mixed, and then 1300g of raw water was added, and fermented at 25°C. At the 96th hour, the fermented product was filled into polypropylene bottles and sealed, and then heated at 25°C. At a temperature of 250 MPa, an ultra-high pressure machine (Quintus food processor, QFP 6, ABB Autoclave systems Inc., Columbus, Ohio, USA) was used for 5 minutes to perform the first ultra-high pressure treatment. After the first ultra-high pressure treatment, fermentation was further carried out for 48 hours, and the second ultra-high pressure treatment was carried out at a temperature of 25° C. and a pressure of 400 MPa for 5 minutes in an ultra-high pressure machine, thereby producing Makgeolli.

Example Embodiment

[0042] Example 2.

[0043] The same as the above-mentioned Example 1, but in the first ultra-high pressure treatment, the ultra-high pressure treatment is performed at a temperature of 25°C and a pressure of 150 MPa for 3 minutes, and then further performed at the same temperature and a pressure of 250 MPa 2 minutes of ultra-high pressure treatment to produce Makgeolli.

Example Embodiment

[0054] Experimental example 1. Determination of pH, acidity, ethanol, and reducing sugar

[0055] The pH, acidity, ethanol and reducing sugar were measured using the Makgeolli produced in the Examples and Experimental Examples, and the results are shown in Table 1 below.

[0056] 1-1. pH: measured with a pH meter (Orion 2-star Benchtop, Thermo scientific, USA).

[0057] 1-2. Acidity (%): Add 1% (v / v) phenolphthalein as an indicator to the Makgeolli, and add 0.1N NaOH solution drop by drop until the color of the Makgeolli becomes bright red. This is then converted into the lactic acid content (%) for calculation.

[0058] 1-3. Ethanol (%): After 100ml of Makgeolli is distilled using a distillation device (Wise Therm WHM, DAIHAN, Korea), the alcohol content (%) is measured with an alcohol meter. According to Gay-Lussac (Gay -Lussac) alcohol conversion table for temperature correction.

[0059] 1-4. Reducing sugar (%): Add 0.5g of dinitrosalicylic acid, 8g of NaOH, and 150g of potassium ...

Abstract

The present invention relates to a method for producing Makkolli (Korean traditional raw rice wine) treated under ultra high pressure and Makkolli produced by using the method, which includes the steps of: primarily treating hard boiled rice fermented with malted rice with ultra high pressure for a time between 60 and 120 hours after the beginning of the fermentation; and then secondarily treating the hard boiled rice additionally fermented for 30 to 60 hours with ultra high pressure, wherein the primary ultra high pressure treatment is performed so as to maintain germs required for enhancing desired properties, so that the remaining germs cause the secondary fermentation, thus increasing the content of reducing sugar and providing excellent functionalities like smooth taste.

Description

technical field [0001] The present invention relates to a method for producing ultra-high pressure treated makkolli wine which can increase the content of reducing sugar, exhibit excellent functional properties such as soft taste, and can prolong the storage period, and the ultra-high pressure treated makkolli wine produced thereby. Background technique [0002] Generally, makgeolli is a traditional Korean liquor fermented by steaming glutinous rice, japonica rice, barley, flour, etc. and mixing it with koji and water. [0003] This kind of makgeolli wine is a natural food fermented naturally by pure microorganisms. It is both wine and healthy food. It is rich in various nutrients, such as more than 10 kinds of essential amino acids related to the metabolism of the human body, especially Lysine (lysine), which is relatively low in general grains, also contains organic acids that quench thirst with a slightly sour taste, acetylcholine that helps liver function, protein, and B...
