[Filtration step] Using a cross-flow filter (Lab Unit M10 manufactured by Alfa-Laval) under the following conditions, the extract obtained in the extraction step was filtered to obtain a filtrate.
  • Example 2 A plant extract was obtained in the same manner as in Example 1, except that the average pore size of the filtration membrane in the filtration step was changed from 0.2 ⁇ m to 5,000 Da (indicating that the filtration capacity is 5,000 Da).
  • Example 3 A plant extract was obtained in the same manner as in Example 1, except that the average pore size of the filtration membrane in the filtration step was changed from 0.2 ⁇ m to 100,000 Da.
  • ⁇ Nicotine analysis after electrodialysis> The ratio of nicotine in the plant extract after electrodialysis was determined by a method according to German Standardization Organization DIN 10373. That is, 250 mg of the plant extract is collected, 7.5 mL of 11% aqueous sodium hydroxide solution and 10 mL of hexane are added, and extracted with shaking for 60 minutes. After extraction, the supernatant hexane phase was subjected to a gas chromatograph mass spectrometer (GC/MS) with samples taken at 1 hour, 2 hours, 4 hours, 6 hours, and 8 hours before extraction and after extraction. The nicotine-derived peak area ratios of the samples before and after dialysis were derived and evaluated.
  • GC/MS gas chromatograph mass spectrometer
  • the nicotine ratio before extraction was set to 1 (denoted as “0 hour” in Table 1 and FIG. 2), and the nicotine ratio at other times was relatively evaluated. Evaluation results are shown in Table 1 and FIG. In addition, "-" in Table 1 indicates that the measurement was not performed.
  • Example 2 A plant extract was produced under the same conditions as in Example 1 in Experiment 1 above, except that the applied voltage in the dialysis step was changed from 10V to 30V. Using the plant extract, protein residual degree measurement and nicotine analysis were performed under the same conditions as in Experiment 1 above. Table 2 shows the results of this analysis. Furthermore, the nitrate ion (NO 3 ⁇ ) concentration of each sample was separately measured and evaluated. This evaluation result is shown in Table 2 and FIG.
  • the method for producing a plant extract according to this example can reduce the protein residue and nitrate ions in the plant extract, and increase the speed of nicotine reduction in the supernatant after extraction. , that is, it was found that the nicotine content in the plant extract can be efficiently controlled. Therefore, from Tables 1 and 2 and FIGS. 4 and 6, it was found that the method for producing a plant extract according to this example can efficiently control the nicotine content in the plant extract.
