Beer flavor stability analyzer

Simple beer flavor stability test system by accelerating aging method with the help of ESR-Spectrometer SPINSCAN XB

SPINSCAN

LINEV Systems SPINSCAX XB - Beer quality

Basic information

Flavor stability relates to the rate of flavor change through the shelf-life of packaged beer. The fermentation and the influence of yeast are key control points in the production of beer where flavor stability may be altered.

Experiment with brewing technique and use Paramagnetic Resonance Spectroscopy to predict when beer is getting bad.

Electron Paramagnetic Resonance Spectroscopy is a unique tool for direct free radicals detection. Accelerated beer aging test with ESR spin-trapping assay method is the easiest way and shorter analysis time to estimate the shelf life of beer.
