Abstract This research aimed to evaluate the influence of different packaging materials (glass bottle, PET bottle, aluminium can and keg) on eleven (acetaldehyde, dimethyl sulphite, ethyl acetate, isoamyl acetate, propanol, isobutanol, isoamyl alcohol, diacetyl, higher alcohols, esters and pentanedione) industrial pale lager beer volatile compounds concentration changes and their stability during a six-month storage time. The analyses were performed on a single type of pale lager beer under different packaging regimes. The results showed that diacetyl and pentanedione were significantly higher in PET bottles than in other packaging (especially glass bottle). Dimethyl sulphide concentration was, at the end of a six month storage, significantly lower (5 μg/L) in PET bottles than in glass bottle (48 μg/L). Can and keg also showed good preservation properties for volatiles. This is important for the brewing industries because the reported changes influence the consumers’ perception and greatly affect the acceptance of beer.

包装材料对淡啤酒挥发性成分的影响

摘要 本研究旨在评估不同包装材料(玻璃瓶、PET瓶、铝罐和小桶)对十一(乙醛、亚硫酸二甲酯、乙酸乙酯、乙酸异戊酯、丙醇、异丁醇、异戊醇、双乙酰、高级醇、酯和戊二酮)工业淡色拉格啤酒挥发性化合物的浓度变化及其在六个月储存时间内的稳定性。分析是在不同包装方式下对单一类型的淡色拉格啤酒进行的。结果表明,PET瓶中双乙酰和戊二酮的含量明显高于其他包装(尤其是玻璃瓶)。在六个月的储存期结束时,PET 瓶中的二甲基硫化物浓度 (5 μg/L) 显着低于玻璃瓶中的 (48 μg/L)。罐头和小桶也显示出良好的挥发物保存性能。这对啤酒行业很重要,因为报告的变化会影响消费者的看法,并极大地影响啤酒的接受度。
