In addition, due to environmental factors such as outbreaks of foot-and-mouth disease, it is difficult to maintain proper production of Korean beef.

Looking at the previous case, we experienced a case of a sharp drop in the price of Korean beef when the number of breeding heads reached 2.94 million heads in 1996 and 3 million heads in 2012. Now is the time to prepare for export market development.

Due to the nature of Korean beef, which does not have a long shelf life due to quality changes, refrigerated Korean beef products are difficult to consume in a short period of time when exported, so there are cases in which they are frozen and sold as frozen products.

However, in the case of selling refrigerated products as frozen products as described above, quality change is prevented, but overseas consumers do not feel the excellent quality of Korean beef as it is, and there is a problem in that product quality and high-quality image are deteriorated.

In order to prevent this, a method of distributing refrigerated Korean beef products by applying a cold chain was used, but a problem occurred in that distribution costs increased too much.

Therefore, it is necessary to develop technology that can maintain the quality of Korean beef (livestock product) for a long period of time so that the export of refrigerated products is easy, the high cost of distribution is not consumed, and the product quality and high-quality image of Korean beef can be maintained.

[ Experimental Example ] plasma water Antibacterial activity evaluation

In order to evaluate the antibacterial activity according to the plasma water treatment according to the present, the experiment was conducted by preparing experimental groups 1 to 3 as follows and varying the plasma treatment conditions (time: 0 min, 30 min, 60 min).

For the preparation of the experimental group, Listeria monocytogenes was cultured in tryptic soy broth (BD Difco ^TM, , MD, USA), ① 4log (2.8~4.2×10^4) CFU/mL, ② 6log (2.8~4.2 ×10^6) CFU/mL, ③ 8log(2.8~4.2×10^8) CFU/mL prepared as an inoculum and evenly inoculated into tryptic soy agar (BD Difco ^TM, , MD, USA) using a spreader, experimental group 1 to 3 were prepared. The concentrations (Listeria monocytogenes concentration) of experimental groups 1 to 3 were 3log(2.8~4.2×10^4) CFU/cm ² , 5log(2.8~4.2×10^6) CFU/cm ² , 7log(2.8~4.2×10 ^8) CFU/cm ² .

The volume of the plasma water generator (reaction tank for low-temperature plasma treatment) was 10 L, and the experiment was conducted with a warm-up time of 30 minutes for each experiment to minimize the influence from the outside of the reaction tank. In addition, the low-temperature plasma water reacted in the generation unit (reactor) was discharged at a rate of 1 ml / min at a distance of 30 cm through the spray unit, and the experimental groups 1 to 3 were treated for 0 minutes, 30 minutes, and 60 minutes after 7 hours, respectively.

After treatment, put each in a 3M stomacher bag for stomach markers containing 0.1% (w/v) peptone water, stomaching at level 2 for 2 minutes (Digital Embo mixer, BNF Korea, Korea), and tryptic soy agar (BD Difco ^TM , MD , USA) was cultured at 30 ° C for 24 to 48 hours to measure the number of viable cells.

The results are shown in Table 1, FIGS. 12 and 13.

As shown in Table 1 and FIGS. 12 and 13, as the plasma water was treated for 30 and 60 minutes, experimental group 1 was 5 log (7.0 × 10 ^ 5) CFU / cm ² , 5 log (1.5 × 10 ^ 5) CFU /cm ² , experimental group 2 was inhibited by 6log(8.6×10^6) CFU/cm ² , 5log(2.3×10^5) CFU/cm ² , experimental group 3 was inhibited by 9log(4.5Х10^9) CFU /cm ² , 8log (1.7Х10^8) CFU/cm ² was confirmed to be inhibited.

On the other hand, the inhibitory ability tended to increase as the inoculation concentration increased, but in experimental group 3, it was shown that the inhibitory ability could be improved more when the treatment time was extended. Therefore, it was thought that a longer treatment time would be required to effectively inhibit bacteria in a wide range of concentrations.
