Using a 30% concentration of PEG60O0 solution and ammonium sulfate to form a two-phase aqueous extraction of VB,. Fixed other conditions remain unchanged, with PEG quantities of 4.0 and 5 After extraction, the fluorescence intensity of the organic phase was determined to be 26.6, 24.4, and 22 2, indicating that the smaller the volume of PEG, the greater the enrichment degree. However, considering the volume requirement of the colorimetric dish, the dosage of PEG was determined to be 40 mL. The experiment found that as the amount of salt increased, the fluorescence value of the organic phase gradually increased, while the volume of the organic phase also gradually decreased. Considering the volume requirement of the colorimetric dish, the volume of ammonium sulfate solution was 40 mL.
