Description
| - Vliv esterasové aktivity v nepasterovaném asepticky plněném nepasterovaném pivu (cs)
- Yeast extracellular esterase is mainly inactivated during pasteurization of beer, but not in aseptic processing of non-pasteurized beer. Effects of esterase activity on the volatile compounds composition and flavour stability of aseptically packaged non-pasteurized beer during storage were assessed. Analysis of volatiles using SPME-GC-MS showed that presence of esterase did not result in decreases in total ester concn. during storage at 30°C for 12 wk; decreases were, however, observed in concn. of octyl acetate and ethyl hexanoate. At the start of storage, sensory properties were detectably different for the pastuerized and non-pasteurized beers. However, these sensory differences became udetectable during storage, possibly because changes due to esterase activity were masked by sensory changes due to oxidation and other decomposition reactions.
