[0037] (Example 1: Lactobacillus species derived from Artemisia princeps) For mugwort leaves, during the 2-hour period of the day, one hour before and one hour after sunrise. It is believed that the number of lactic acid bacteria is maximized during this time. Also, outside of this time period, the number of lactic acid bacteria decreases. It is believed that photosynthetic bacteria increase slightly. Therefore, during these two hours, the mugwort leaves Approximately 20 cm from the tip was collected. The 6.3 kg of mugwort leaves that were collected were immediately processed. Place it in the first pickling barrel lined with a plastic bag, and wrap it in mugwort leaves with 3.2 kg of molasses and 0. After sprinkling 6 kg of coarse salt, the opening of the plastic bag was closed and sealed. A weight was placed on top, and the mugwort leaves were pickled.

[0038] A few days after the pickling liquid had risen to the top of the mugwort leaves, the weight was removed. Next, into the second pickling barrel, Add 10 liters of chlorine-free water for rinsing, and put the pickled mugwort leaves into the water. I added 10 kg of pickling liquid. Furthermore, I prepared a third pickling barrel and placed a metal slab over the opening of the third pickling barrel. I placed a mesh filter on top. I took mugwort leaves little by little from the second pickling barrel, washing them by hand. Then, place the mugwort leaves on the wire mesh filter at the opening of the third pickling barrel, lightly pressing them down with your palm, and add the pickling liquid. I narrowed it down.

[0039] After squeezing all the mugwort leaves, pass the remaining pickling liquid from the second batch through a wire mesh filter. It was filtered. Next, molasses (Hateruma brown sugar) was added to the pickling liquid in the third pickling barrel until it reached a final concentration of 10 by weight. The coarse salt was dissolved in the mixture so that the final concentration was 3% by weight. Then, the third pickling process was carried out. Fermentation was initiated by raising the ambient temperature of the vat to approximately 30°C. Initially, large bubbles began to form. The foaming was observed, gradually changing to fine bubbles, and finally subsiding. Approximately one week later The pH was around 3.8 when the fizzing subsided. The pickling liquid at this time was used as a mugwort fermentation liquid. The obtained mugwort fermentation liquid was then heated at 70°C for 30 minutes to kill the bacteria. We obtained a fermented mugwort liquid.

[0041] (Example 2: Lactobacillus genus derived from Angelica keiskei) In the case of Ashitaba, the milk is released during the 2-hour period around sunrise, one hour before and one hour after. It is believed that the number of acid-producing bacteria is maximized during this time. Also, outside of this time period, the number of lactic acid bacteria decreases. It is believed that photosynthetic bacteria increase during this two-hour period. The stems were harvested. The 6.3 kg of harvested Angelica keiskei were immediately placed in a plastic bag. Place in pickling barrel 1, sprinkle 3.2 kg of molasses and 0.6 kg of coarse salt over the Angelica keiskei, then... I closed the opening of the plastic bag and sealed it. I placed a weight on top of the plastic bag and pickled the Angelica keiskei inside. .

[0042] A few days later, when the pickling liquid had risen to the top of the Angelica leaves, the weight was removed. Next, in the second pickling barrel, Add 10 liters of chlorine-free water for rinsing, and then add the pickled Angelica keiskei and 10 kg of other ingredients to the water. The pickling liquid was added. Furthermore, a third pickling barrel was prepared, and a wire mesh filter was placed over the opening of the third pickling barrel. I put the ta on. From the second pickling barrel, I took out the angelica little by little, rubbing and washing it by hand, and the third I lightly pressed the angelica leaves with my palms against the wire mesh filter on the opening of the pickling barrel and squeezed out the pickling liquid.

[0043] After squeezing all the Angelica keiskei, the remaining pickling liquid in the second batch was filtered through a wire mesh filter. Next, molasses was added to the pickling liquid in the third pickling barrel so that the final concentration was 10% by weight. Coarse salt was dissolved in the mixture to a final concentration of 3% by weight. Then, the ambient temperature of the third pickling barrel was adjusted to approximately Fermentation was initiated by raising the temperature to 30°C. Initially, large bubbles were observed, and gradually... The foaming gradually changed to fine bubbles, and finally subsided. About a week later, when the foaming had stopped. The pH was around 4.0. The pickling liquid at this time was used as the Angelica keiskei fermentation liquid. A portion of the Angelica keiskei fermentation liquid was heated at 70°C for 30 minutes to kill the bacteria, resulting in a heat-treated Angelica keiskei fermentation liquid. .

[0044] Unheat-treated Angelica keiskei fermented liquid is processed using a next-generation sequencer (MiSeq, Illumina).
