摘要：In this research the effect of total packaging oxygen on the quality of bottled (glass bottle) lager beer during storage was studied. The beer was stored in a dark room at temperature of 22 - 25°C and it contained three different concentrations of total packaging oxygen: 0,09, 0,29 and 0,63 mg/L. During the 98 days storage period the concentration of trans-2-nonenal, a well known indicator of oxidation processes in the beer, was monitored. The results obtained in this research clearly show that the concentration of trans-2-nonenal is not directly related to the total oxygen concentration in the bottled beer. Sensory analysis of beer was also performed and obtained results clearly show that higher concentrations of total packaging oxygen directly effects beer quality and flavour.
