PHOTO-INDUCED FEATURES OF SOME LAGER BEERS

Luminescent beer constituents were studied using total luminescence techniques. Significant spectral variations observed between various samples including fresh and photooxidized samples confirmed the potential of the method as a tool for beer typifying and quality control. Quantitative analysis should be possible using appropriate chemometric tools. Singlet oxygen was confirmed to be an active oxygen species in the photooxidation of beers. Additional tests of beer volatiles performed using an electronic nose with subsequent principal component data analysis proved that this method can positively discriminate various beer samples and also recognize the effects of photooxidation and loss of flavour and taste in contact with the atmosphere.

W latach 2022-2024 kwartalnik naukowy Polish Journal of Food and Nutrition Sciences realizuje projekt nr RCN/SP/0520/2021/1 finansowany ze środków budżetu państwa – Ministerstwo Edukacji i Nauki w ramach programu „Rozwój czasopism naukowych”. Dofinansowanie wynosi 120 000 zł. W ramach projektu podejmowane są działania zmierzające do podniesienia poziomu praktyk wydawniczych i edytorskich, zwiększenia wpływu czasopism na rozwój nauki oraz utrzymania się czasopism w międzynarodowym obiegu naukowym.

In the years 2022-2024, the scientific quarterly Polish Journal of Food and Nutrition Sciences accomplishes a project no.
