UV-Vis analysis of food samples: tips and tricks for QA/QC

Overcome the challenges associated with complex food samples and streamline your QA/QC processes by harnessing the full potential of UV-Visible absorption spectroscopy.

UV-Visible absorption spectroscopy is a popular technique for quality assurance and quality control in the food industry. While QA/QC testing of simple products like food dyes can be straightforward, how can successful analysis of complex food products be achieved?

Working with complex food samples can pose challenges. With multiple components including absorbers present, it becomes crucial to ensure accuracy in the analysed results. As a highly versatile and non-destructive technique, UV-Visible absorption spectroscopy is a powerful and reliable method for quantitative analysis. This webinar will demonstrate the application of UV-Visible spectroscopy in food analysis and also provide best practices to maximise the efficiency and accuracy of this technique.

Dr. Jennifer Empey-Kohl, Applications Scientist with Thermo Fisher Scientific, will address common issues that can arise during the analysis process and offer valuable tips on environmental considerations, instrument parameters, and sample preparation to optimise your results. She will also present best practices to maximise the efficiency and accuracy of this technique.

Key learning points:

  • Gain insights into best practices for UV-Visible absorption spectroscopy, including sample preparation and how to choose the best instrument parameters
  • Learn strategies for analysing UV-Visible spectra of matrixed samples, as well as how to correct for known contaminants
  • Understand environmental and sample factors that can affect the measured absorbance of a given analyte
  • Take advantage of the live Q&A to ask your own questions and obtain expert guidance
