ESR applications in food & beverage industry

Antioxidant  Activity Analysis, Flavor Stability of beer & lipids, and Food Irradiation Control

ESR spectrometer for food chemistry, safety and quality

Whether it is a beer brewery next door or a large scale, multi-product industrial food production company, the MiniScope MS 5000 spectrometer can be used to anlayze the food safety and quality. 

For example:

  • flavor stability of beer and beverages

  • determination of radicals in malt, coffee beans, fruit etc.

  • quality control of coffee & wine

  • methods to evaluate antioxidant content in food


  • and many more

Advantages of ESR/EPR spectrometer MS5000

  • High sensitivity and spectrometer stability also for aqueous samples due to powerful automatic spectrometer self-adjustment routines

  • Auto-sampler for efficient sample throughput

  • intuitive user-interface uses recipes to modify measurement parameters for simple sample handling, also by unskilled persons

  • Automatic time-dependent and transient ESR-measurements in timescales from 2µs time-resolution to hours or days

  • g-factor as abscissa for ESR spectra (default: B-field)

  • Very high reproducibility of ESR line positions on magnetic field scale by automatic microwave-frequency readjustment
