{COUNTERFEIT LIQUOR DETERMINATION KIT}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a counterfeit liquor discriminating kit, and more particularly, to a counterfeit liquor discriminating kit capable of discriminating whether or not a sample is counterfeited by using acidity and density of a sample.

In general, whiskey is a distillate produced by fermenting grain (barley, corn, wheat, etc.). It is used to cast a standardized product using a raw solution that has undergone aging for at least two or three years, Of alcohol.

Scotch whiskey, which is the origin of Scotland, accounts for 90% of whiskey imported from the country. In addition to the domestic sales of whiskey in 2013, "Windsor", "Imperial" and "Imperial" 'Scotch Blue' is a product that used Scotch whiskey as an undiluted solution.

According to the Customs Service, the tax on imported whiskey is about 132.32% (20% custom duty, 86.4% tax and 25.92% education tax) compared to the port and airport arrival price (CIF) Taxes are included and prices are set. In order to increase sales profits with these expensive whiskeys, manufacturers fake the liquor, and the vendor sells it to consumers by introducing counterfeit whiskeys.

To manufacture forged whiskeys so far, firstly, it is mixed with industrial ethanol, caramel color and various food additives. Second, it is mixed with low-priced liquor soju and sold in expensive bottles. Third, various residual liquor is collected and reused And selling them in bottles.

Whiskey manufacturers are developing and introducing individual anti-counterfeiting systems in order to eradicate counterfeit whiskeys manufactured by the above-mentioned methods. The nationwide introduction of RFID will supervise the entire process of production, distribution, storage and consumption, After that, it strengthens punishment standards and also operates a report award system. Korean Patent Laid-Open No. 10-2009-0055105 is a related prior art.

For example, companies that use anti-counterfeiting systems include: First, 'C-Color' of Hi-Scotty is attached to the bottle cap of the whiskey bottle with patented technology of USA 3M to discriminate the authenticity of genuine whiskey do. Second, Diageo Korea distinguishes authenticity by applying additional 'Checker' and 'Yes Code', and additionally attaches 'Hologram'. Third, Lotte Chilsung applies DNA system using special ink, which distinguishes genuine products with the color change of label. Fourth, Jinro Valentines uses 'OK Mark' and develops and applies various technologies to distinguish counterfeit whiskey by introducing 'Mobile Activation Service' which judges authenticity using smart phone.

Also, nationwide, we are introducing RFID, which contains information on production, distribution, storage and consumption of electronic tags, and intend to enhance its usability by linking the applications of smart phones with RFID tags.

However, the anti-counterfeiting system developed and applied by the whiskey manufacturing companies mentioned above and the RFID system introduced in the country are technologies suitable for judging the authenticity of whiskey before the opening by incorporating the technology into the bottle itself, But it is weak to do. Although the necessity of the forgery whiskey discrimination technology using the actual contents after opening this is arising, the measuring instruments which can measure the presently are relatively expensive or large, and it is difficult for the whiskey consumer or the user to use it immediately in the field when necessary, And it takes a lot of time and money to measure whether or not a counterfeit is detected.

Therefore, it is necessary to study the technology that can easily discriminate whether or not alcohol is counterfeited, without using a separate measuring instrument using the actual sample after opening.

An object of the present invention is to provide a counterfeit liquor discriminating kit which can discriminate authenticity of a mainstream by applying the principle of acidity reaction and capillary phenomenon without using a separate measuring device using actual samples.

In this case, the lift eliminators 24, 25 and 26 are additionally included in order to remove the lift in the sample tunnel part 9 after the manufacturing, and the inner sample outlets 19 and 20 are removed from the lift eliminator 24, .

Hereinafter, the operation of the forgery liquor discriminating kit according to one embodiment of the present invention will be described.

When a mainstream (for example, whiskey) sample is injected into the sample inlet 1, it is moved to the acidity changing zone 3 through the sample introduction ramp 2. The pH test paper (pH test paper) located in the acidity change area (3) is fixed to the test paper fixing parts (5, 6) of the top plate, and the color changes through a chemical reaction with the injected sample. The color thus changed can be visually confirmed through the first display 4 of the upper panel.

The counterfeit liquor discriminating kit according to an embodiment of the present invention includes overcharge tanks 21 and 22 to prevent the sample from flowing back to the sample inlet 1 when the sample is excessively charged, have.

The sample overflowing can be continuously discharged through the inner sample outlet (19, 20). The samples discharged into the kit may be discharged to the outside through the external sample outlet 23 exposed to the outside. The external sample outlet 23 can perform three functions. Firstly, since it is exposed to the outside, air circulation is generated by interlocking with the sample input port 1, so that the sample can be moved to the sample tunnel part 9 easily. Second, when there is no overflow of the sample, the amount of the sample in the sample tank can be held constant without discharging the sample to the outside by the tension of the sample and the kit material. Third, when the sample overflows, the sample that temporarily flows into the kit can be discharged to the outside.

According to an embodiment of the present invention, the test paper placed in the acidity change area 3 can be replaced with a pH indicator reagent. When the pH indicator reagent is replaced with the pH indicator reagent, the second display 16, , The whiskey sample itself can be visually checked for changed color.

The sample subjected to the chemical acidity reaction is moved to the sample tunnel portion 9 through the sample tunnel portion inlet 8, and the sample tunnel portion can be formed with an inner diameter of about 1 mm or less. The whiskey injected into the sample injecting section 1 moves to fill the sample tunnel section 9. The forgery liquor discriminating kit which keeps the sample height of the sample tunnel section 9 constant, 20) on both sides. In addition, the forgery liquor discriminating kit may include over-capacity tanks 21 and 22 in preparation for oversampling of a sample, and an outer sample outlet 23 is located under the sample tunnel 9 to detect the inner sample outlet 19 and 20 may be discharged to the outside of the forgery liquor discriminating kit. The sample outlets 19, 20, 21, 22, 23 cause air circulation so that the sample can be easily moved into the sample tunnel 9.

The sample filled with the sample tunnel portion 9 at a predetermined height moves along the capillary of the second display 16. The capillary is fixed to the fixed portions 11, 12, 13 and 14, And the other side of the air vent hole 17 can be connected to the air vent hole 17. The capillary phenomenon occurs through the above-described structure, and the moving distance of the sample through the capillary phenomenon can be visually determined through the second display 16 of the upper plate.

The following equation (1) is a capillary formula, and the length of a sample taken on a capillary can be measured through Equation (1).

Where h is the length up, γ is the surface tension, θ is the contact angle, r is the capillary radius, ρ is the density of the sample, and g is the gravitational acceleration.

Since each liquor has a unique surface tension and density, h can be varied, and the authenticity of the liquor can be determined.

4 shows a counterfeit liquor discriminating kit according to an embodiment of the present invention.

As shown in the figure, the counterfeit liquor discriminating kit can be manufactured by using the 3D printer and the ABS resin as the upper plate of Figs. 1 and 2 and the lower plate of Fig. The kit 100 may include a first display 4 indicative of a pH state and a second display 16 indicative of a travel distance of the sample.

The front of the top plate can be designed using label paper and laser printer. In fact, the counterfeit liquor discrimination kit can be produced in a width of 84.09 mm, a length of 50.18 mm, and a height of 4.18 mm.

The counterfeit liquor discriminating kit 100 manufactured using the 3D printer and the ABS resin material may be limited in size and properties but may be made of materials having elasticity and flexibility such as PDMS (Polydimethylsiloxane), PMMA (Poly methyl methacrylate ), PC (Polycarbonate), etc.) and microfluidics technology, it is possible to overcome limitations on the size and properties of the kit.

The capillary phenomenon is different depending on the inherent viscosity in the process of whiskey ripening. More specifically, the whiskey supplied to the consumer is 40% of the alcohol content, but the forged whiskey is mixed with the ethanol and water in the whiskey, By varying the degree of capillary phenomenon, it is possible to discriminate the authenticity of whiskey.

The whiskey used in the capillary phenomenon experiment is Windsor belonging to the Scotch whiskey, which is supplied to the consumer at a 40% alcohol content. In this experiment, under the assumption of forged whiskey manufacturing, the whiskey is 40% Prepare a sample by adding ethanol.

FIG. 5 shows the result of the measurement of the fabricated sample through the kit 100 shown in FIG.

5 is a graph showing the relationship between the alcohol frequency and the capillary phenomenon according to an embodiment of the present invention.

As shown, the position of the genuine whiskey is displayed at 10.1 mm on the second display 16, and it is shown that the sample travels more travel distance to the lower map and less travel distance to the altitude map.

FIG. 6 is a graph showing an experimental result of applying a capillary sensitivity improving method according to an embodiment of the present invention.

The graph shown shows the distance traveled by the sample due to the capillary phenomenon, measured by a specific angle, while tilting the commercial capillary.

According to the capillary phenomenon described above, capillary phenomenon of the whiskey is limited to 40% of alcohol whiskey. However, according to the measured results, it is difficult to distinguish the alcohol frequency of 60% from 20% Therefore, a method of improving the sensitivity of the capillary to refine it can be further proposed.

According to an embodiment of the present invention, the distance of the capillary to move the capillary length by the change of the slope of the capillary (h / cos?) Can be increased by applying Equation 1 to improve the sensitivity of the capillary phenomenon. As shown, when the tube is tilted at a vertical angle of 70 °, when the alcohol concentration is changed from 20% to 60%, the moving distance of the sample is 10 mm, which is about 3.3 times higher than the reference 0 °.

As described above, as the slope of the capillary increases, the distance that the sample travels through the capillary increases, and the capillary phenomenon results in an increased resolution for characterizing the sample.

FIG. 7 is a diagram illustrating an experimental state of detection of a false feed liquor according to an embodiment of the present invention.

Sample 1 is a genuine Windsor whiskey sample. Sample 2 is a mixture of low-priced wine and genuine whiskey and water and pigment. Sample 3 is low-priced wine, ethanol, water, and water. And 4 is a sample mixed with ethanol, water and pigment. Each whiskey is manufactured by whiskey counterfeiting manufacturing method widely known in the mass media. It is possible to distinguish the authenticity of four samples visually It is difficult to do.

The result of the experiment with the kit 100 according to one embodiment of the present invention is as follows. Sample 1 is a genuine Windsor whiskey. The change in acidity color agrees with the color of the whiskey of the genuine whiskey, As shown in FIG.

Sample 2 is a mixture of low-priced wine, genuine whiskey, and water and a colorant. The acid color change matches the color of the original whiskey, but it is not located exactly at the point of the original whiskey capillary.

Sample 3 is a mixture of low-priced wine, ethanol, water, and coloring matter. It can be confirmed that the color change in acidity shows the dark color different from the color of the original whiskey, but is accurately located at the point of the original whiskey capillary.

Sample 4 is a mixture of ethanol, water, and pigment. The color change of acidity shows a purple color different from that of the original whiskey, but it can be confirmed that it is located exactly at the spot of the original whiskey capillary.

As a result of the above experimental results, the two techniques implemented in the kit, the acidity measurement and the capillary phenomenon measurement technique, are effective for whiskey counterfeiting methods known from the mass media. Especially, 3 and 4, it can be confirmed that even when a sample suitable for the whiskey and the capillary phenomenon is prepared, the color change of the acidity is significantly different because the whiskey is not included. Through the sample 2 including the whiskey, It can be confirmed that even if it can not be done, it is not located at the capillary display point due to the low price of water contained in the production and impurities such as water and coloring matters.

According to another embodiment of the present invention, another type of counterfeit liquor discriminating kit can be manufactured by applying the microfluidics technique.

8 is a view showing a forgery liquor discriminating kit according to another embodiment of the present invention.

As shown in the figure, the counterfeit liquor discriminating kit 200 includes a sample inlet 37 for inputting a sample, a channel 50 connected to the sample inlet 37, and an acidity indicator reagent 40 ).

The channel 50 includes a sample transporting port 38 for transporting a sample by capillary phenomenon, an acidity indicator reagent section 39 where the acidity indicator reagent 40 is located, a capillary tube 40 for detecting whether the sample is falsified, And a zone 41. The smaller the inner diameter of the capillary region 41 is, the longer the distance the sample travels. Therefore, the capillary region 41 can be formed to have a small inner diameter. For example, the inner diameter of the capillary region 41 may be set to 0.1 mm to 1.0 mm to increase the sensitivity of the naked eye identification.

In addition, the inner surface of the channel 50 through which the sample is moved may be made of a hydrophilic material or may be doped with a hydrophilic material to increase the sensitivity of visual identification. The sample injected through the hydrophilic material can move further along the channel. Examples of the hydrophilic substance include natural gums such as caraya, tragacanth, ghatti and guar, synthetic resins such as polyvinyl alcohol and polyvinylpyrrolidone, carboxymethyl, hydroxyethyl, hydroxypropylcellulose, polyacrylic acid, And polyethylamine.

The kit 200 related to one embodiment of the present invention uses acidity measurement and capillary phenomenon, but microfluidics technology is added to emphasize one-time convenience and convenience. More specifically, And does not use the glass capillary required for the capillary phenomenon, so that it is free from the size and the material in the production of the kit.
