As shown in FIG. 1, the polycyclic aromatic hydrocarbon sensing and cooking apparatus 100 according to an embodiment of the present invention includes a cooking unit 110 and a smoke collecting unit 120.

The cooking unit 110 can provide a space for heating and heating the food. At this time, the method of cooking food is not limited to the method of cooking by applying heat, and the food may be cooked using a magnetic field or the like. As a method of generating heat for cooking food, a method of igniting a combustible fuel such as a gas range, a method of applying heat by using a built-in hot wire such as a highlight, and the like can be utilized. In addition, the form of cooking food includes a form in which food can be burnt directly on a grill or the like, a form in which a food is put on a frying pan and baked. However, the above-described example is only for the sake of understanding, and there is no particular limitation on the form and method of the cooking portion. In one example, when food such as meat is heated, oil may be discharged. The blanks 110 may be formed in an arcuate shape so that the discharged oil may flow through the blanks 110. Also, the flowing oil can fall into the oil pan placed at the bottom of the cooker.

The alarm unit 140 may receive an alarm message from the polycyclic aromatic hydrocarbon measuring unit 130 that the polycyclic aromatic hydrocarbon has reached a harmful level to the human body. In this case, the alarm unit 140 can inform the user of the degree of generation of the polycyclic aromatic hydrocarbons and change the cooking conditions. Accordingly, the user can take food containing less polycyclic aromatic hydrocarbons. At this time, the alarm unit 140 can be visually displayed using an optical element (for example, an LED lamp), but it is not limited to this, and an alarm sound may be generated.

On the other hand, the polycyclic aromatic hydrocarbon measuring unit 130 may be coupled to a battery for power supply. At this time, the alarm unit 140 may display a message requesting the user to replace the battery even if the available time of the battery is less than a predetermined time.

In order to confirm the correlation between the amount of polycyclic aromatic hydrocarbons produced during meat cooking and the content of carbon monoxide in cooked smoke, 8 kinds of polycyclic aromatic hydrocarbons (Benzo [a] anthracene, chrysene, benzo [b] fluoranthene, benzo [k] fluoranthene, benzo [a] pyrene, indeno [1,2,3- h] anthracene was measured and carbon monoxide was measured. The content of each polycyclic aromatic hydrocarbon in the meat samples baked for 2 minutes, 4 minutes, 6 minutes, and 10 minutes was analyzed when the temperature of the frying pan was 150 ° C., 180 ° C., and 210 ° C., ), And the amount of carbon monoxide in the smoke was measured with a carbon monoxide measuring device. To extract polycyclic aromatic hydrocarbons, 10 g of homogenized meat samples were placed in a round bottom flask, spiked with 1 [mL] of an internal standard, added with 100 mL of 1 M potassium hydroxide ethanol (KOH ethanol) Alkali decomposition. After the decomposition, rapidly cool, add 50 mL of n-hexane through a reflux condenser, add 50 mL of a solution of ethanol to n-hexane (1: 1) I moved. Separate the water layer and the n-hexane layer by shaking 50 mL of distilled water into the separatory funnel, separate the n-hexane layer, place it in another separating funnel, add 50 mL of n-hexane to the water layer, And the n-hexane layers thus obtained were combined. The n-hexane layer was washed with 50 mL of distilled water, dehydrated by passing anhydrous sodium sulfate, and the eluted solution was concentrated to 2 mL at 37 ° C using a rotary vacuum concentrator. The silica column was used as a purification column. The column was used after activation with 10 mL of dichloromethane and 20 mL of n-hexane. The test solution was added to the activated column and eluted with 5 mL of n-hexane and 15 mL of a 3: 1 solution of n-hexane to dichloromethane. The purified eluate was concentrated with nitrogen at 37 ° C, and the residue was dissolved in dichloromethane to make 1 mL. The solution was passed through a 0.45 μm polytetrafluoroethylene membrane filter (Gas Chromatography Mass Spectrometer GC / MSD). The above-described analysis conditions are shown in Table 1 below.

The results of the above experiment are shown in Table 2.

In Table 2, Total PAHs refers to the total amount of polycyclic aromatic hydrocarbons. For example, when the amount of carbon monoxide generated is 10.67 (mg / kg), the total amount of polycyclic aromatic hydrocarbons generated is 2.32 (占 퐂 / kg). At this time, the polycyclic aromatic hydrocarbons detected include chrysene, benzofluorathene, benzopyrene, benzoperylene, and dibezoanthracene.

On the other hand, FIG. 4, which shows the correlation between the carbon monoxide and the polycyclic aromatic hydrocarbons, was prepared based on the results shown in Table 2. For example, polycyclic aromatic hydrocarbons increased from 2.32 to 3.15 and 3.88 (占 퐂 / kg) while the amount of detected carbon monoxide increased from 10.67 to 12.67 and 14.67 (mg / kg). Accordingly, it can be seen that the content of polycyclic aromatic hydrocarbons increases as the content of carbon dioxide contained in the smoke increases.

It should be noted, however, that the experiments described above are for the purpose of understanding only and do not limit the scope of the technical thought.
