A method for determining the quality of flavors and fragrances by full-wavelength ultraviolet-visible absorption spectroscopy and its application |
| abstract |
The invention discloses a method and application for determining the quality of flavors and fragrances by using full-wavelength ultraviolet-visible absorption spectroscopy technology. Flavor and fragrance diluent, use UV-visible spectrophotometer for full-wavelength spectral scanning; according to full-wavelength UV-visible spectral scanning spectrum and data, obtain the maximum absorption wavelength and absorbance at the maximum absorption wavelength of the fragrance and fragrance to be detected; The absorbance at the maximum absorption wavelength of the fragrance is compared with the absorbance at the maximum absorption wavelength of the standard fragrance and fragrance. If the difference between the absorbance at the maximum absorption wavelength of the fragrance to be detected and the standard fragrance and fragrance is greater than 10-20%, it is judged that The flavors and fragrances to be tested are unqualified. The method provided by the invention can detect the intrinsic quality of the flavor and fragrance by monitoring the color fluctuation of the flavor and fragrance. |
