Abstract Recently, the brewing industry has invested significant resources into the development of new specialty beers, in response to increased consumer demand. Low carbohydrate and novel flavored beers have resulted and these are particularly attractive for consumers, even if technologically challenging to produce. The aim of this work was to produce a low carbohydrate and novel flavored beer in a traditional manner. A Saccharomyces cerevisiae strain isolated from an alternative source (i.e., yeast strain DBVPG 6580 was used in a Brazilian bioethanol production facility) was selected because of its starch degrading character and this yeast was employed in a traditional brewery plant to achieve this goal. The strain DBVPG 6580 was used to ferment worts of different densities (12 and 20°P) and at different fermentation temperatures (18 and 25 °C), to explore possible technological applications. The results demonstrated that yeast DBVPG 6580 was able to degrade dextrins to fermentable sugars, giving an apparent attenuation above 100% and allowing for the production of a low carbohydrate beer by traditional methods. Moreover, strain DBVPG 6580 produced novel flavored beers, rich in fruity, floral, banana and pear flavors. This yeast strain demonstrated that under optimal conditions, it possessed the ability to ferment a high density wort, which could lead to important economic advantages for the producer.

由替代来源的精选酵母菌株生产的低碳水化合物啤酒

摘要 最近，为响应日益增长的消费者需求，酿酒业已投入大量资源开发新型特种啤酒。低碳水化合物和新颖风味的啤酒已经产生，这些啤酒对消费者特别有吸引力，即使生产技术具有挑战性。这项工作的目的是以传统方式生产低碳水化合物和新颖风味的啤酒。选择从替代来源（即，巴西生物乙醇生产设施中使用的酵母菌株 DBVPG 6580）分离的酿酒酵母菌株，因为它具有淀粉降解特性，并且该酵母用于传统啤酒厂以实现这一目标。菌株 DBVPG 6580 用于发酵不同密度（12 和 20°P）和不同发酵温度（18 和 25°C）的麦芽汁，探索可能的技术应用。结果表明，酵母 DBVPG 6580 能够将糊精降解为可发酵糖，明显衰减超过 100%，并允许通过传统方法生产低碳水化合物啤酒。此外，菌株 DBVPG 6580 生产出具有丰富果味、花香、香蕉和梨味的新型风味啤酒。该酵母菌株表明，在最佳条件下，它具有发酵高密度麦汁的能力，这可为生产者带来重要的经济优势。DBVPG 6580 菌株生产出具有丰富果味、花香、香蕉和梨味的新型风味啤酒。该酵母菌株表明，在最佳条件下，它具有发酵高密度麦汁的能力，这可为生产者带来重要的经济优势。DBVPG 6580 菌株生产出具有丰富果味、花香、香蕉和梨味的新型风味啤酒。该酵母菌株表明，在最佳条件下，它具有发酵高密度麦汁的能力，这可为生产者带来重要的经济优势。
