The present invention relates to a method for producing purified distilled spirits, and more particularly, to a method for producing distilled spirits that removes distinctive odors and tastes that cannot be removed even by distillation. Conventionally, brewed alcoholic beverages generally have a low alcohol concentration if they are simply fermented and the residue removed, so distillation is used to increase the alcohol concentration, and the products produced in this way are not drinkable as distilled alcoholic beverages. It had been. However, even after being purified through distillation, there were still impurities that affected the taste and aroma, or they were sometimes formed or mixed in during the distillation process. As a result, there are peculiar tastes and odors caused by raw materials, as well as peculiar tastes and odors caused by esters and aldehydes produced during distillation during fermentation.
The smell was difficult to remove. For example, shochu immediately after distillation still contains oily esters, of which ethyl linoleate in particular undergoes air oxidation and generates an oily odor, leading to a decline in quality. Furthermore, because the ethyl esters of higher fatty acids were insoluble, they sometimes became cloudy or floated in the form of oil. Conventionally, filtration, activated carbon treatment, or ion exchange resin treatment has been performed to remove the above-mentioned impurities.
For example, shochu containing oily esters has been cooled to below 10°C and filtered to remove it, or if a lighter flavor is desired, it has been treated with activated carbon. However, although this method provides some improvement, there are still problems such as ester and aldehyde odors remaining, and in some cases, a burnt odor from the activated carbon. Therefore, the inventor of the present invention has conducted extensive research into a method for producing purified distilled spirits that removes the distinctive taste and odor of distilled spirits to such an extent that they are not particularly bothersome to drinkers, and that does not introduce impurities during the purification process. They came up with the idea of utilizing silica gel and completed the present invention. That is, the gist of the present invention is that, in the production of purified distilled spirits, solid silica gel is treated by mixing and stirring at room temperature in a liquid state before or after the distillation process, and a solid silica gel layer is A method for producing refined distilled spirits, characterized by processing the refined distilled spirits by passing the distilled spirits through the process. The alcoholic beverages processed here include shochu made from potatoes, barley, buckwheat, brown sugar, etc., awamori, rum, Korean liquor, vodka, whisky, gin, brandy, cognac, etc., and their undistilled products. It will be done. The silica gel used in the treatment may be in the form of granules, small spheres, tablets, or powder, but powder, small spheres, or granules are preferred because they have a faster impurity adsorption rate. The silica gel treatment method involves simply adding silica gel to sake, stirring well to allow the silica gel to adsorb impurities, and then removing the silica gel. If the siligel is in the form of a tablet, it can be removed by simply pulling it up, and if it is in the form of granules, spherules, or powder, it can be removed using a filter paper or the like. Alternatively, the silica gel itself can also be used as a filter material.
For example, this can be done by filling a column or the like and letting the liquor pass through it. The treatment temperature is room temperature. This is because cooling or heating energy is required even if the temperature is lower or higher than this, which is disadvantageous, but it is also possible to conduct the process at a temperature of 5 to 100°C. If the temperature during treatment is too low, the adsorption rate of impurities on the silica gel will be reduced and purification will take time; if the temperature is too high, the adsorption capacity of the silica gel will be reduced. The silica gel that can be used can be applied to the present invention if it is generally used for drying, but from the viewpoint of adsorption performance, for example, silica gel with a BET specific surface area of 100 to 1000 m 2 /g and a pore volume of 0.3 to 2.0 ml/g is suitable. ,
It is preferable that the average pore diameter is 10 to 500 Å. Among them, it is especially effective in removing impurities from alcoholic beverages.
BET specific surface area 300~800m 2 /g, pore volume 0.3~
1.2 ml/g and an average pore diameter of 20 to 200 Å are preferred. The amount of silica gel added to sake is 0.001 to 1
% (the same below weight %) is preferable, and more preferably 0.01~
0.5% is preferable in terms of purification efficiency. If it is less than 0.001%, the purification effect will be insufficient, and if it exceeds 1%, the effect will not increase in proportion to the amount of silica gel, and the silica gel will be wasted. Analytical tests show that impurities are selectively removed here. [Test example] Thyroid 244 in 50ml of commercially available shochu in a flask
(Silica gel manufactured by Fuji Davison Chemical Co., Ltd., the same hereinafter)
1% of was added and stirred at 25°C for 1 hour. This product was suction-filtered through a filter paper (Toyo Roshi Co., Ltd. 5C) as a sample, and commercially available shochu as it was was used as a comparison sample and analyzed by liquid chromatography. The results are shown in the graphs of FIGS. 1 to 6. Comparative sample 1 of commercially available sweet potato shochu shown in FIG. 1 and sample 1 treated with silica gel are shown in FIG. Sample 1 has peaks P1 and P compared to comparative sample 1.
2, P3 is decreasing, and Q1 at the valley is decreasing less rapidly. The most remarkable point here is that peaks P4 and P5 have disappeared. FIG. 3 shows comparative sample 2 of commercially available barley shochu, and FIG. 4 shows sample 2 treated with silica gel. Sample 2 has peaks P11 and P compared to comparative sample 2.
12, P18 has decreased, and the notable point is P1
3, P14, P15, P16, P17, P19,
This is the point where P20 almost disappears. Figure 5 shows comparative samples 3 and 6 of commercially available brown sugar shochu.
The figure shows sample 3 treated with silica gel. Sample 3 has peaks P21 and P compared to comparative sample 3.
22 has almost disappeared. As mentioned above, if treated with silica gel,
It can be seen that impurities in distilled spirits can be selectively removed. As described in detail above, the present invention provides treatment by mixing and stirring solid silica gel at room temperature in a liquid state before or after the distillation step, or by passing it through a solid silica gel layer. By doing this, higher fatty acid esters in alcoholic beverages and miscellaneous trace components that adversely affect the flavor are selectively adsorbed to the silica gel, making it easy to produce clear, flavorful, and higher quality shochu. It can be obtained efficiently. Moreover, according to this method, great effects can be obtained even with only a small amount of silica gel. Next, an example will be described. Example 1 Barley shochu with an alcohol concentration of 42.7% is diluted with water to 24.8% to prepare a sample solution. Silica gel is Thyroid 63, Thyroid 244,
Thyroid 404 was used. This Thyroid 63,
The BET specific surface area (m 2 /g) of 244 and 404 is 700,
300, 300, each pore volume (ml/g) is 0.4, 1.6,
1.2, each average pore diameter (Å) is 20, 210, 160.
For comparison, activated carbon for brewing (commercially available) was used. The above-mentioned silica gel or activated carbon was added (wt%) to sample solution 1, followed by stirring and filtration to obtain purified shochu. Table 1 shows the taste and aroma sensory tests conducted by six people on the above-mentioned shochu. The criteria for judging were 1 for good, 2 for fair, and 3 for poor based on the overall judgment of both taste and aroma, and the scores were given by the average of the six people. The lower the score, the better. Four types of commercially available activated carbon were used. As a result, the blank (untreated) product is cloudy and has an oily odor, coarse taste, and astringent taste, while the activated carbon-treated product is clear but has a burnt odor and a rough taste. On the other hand, those treated with silica gel are clear;
The flavor is round and the umami comes out.
