Brewer's spent grain (BSG) is the most abundant by-product generated from the beer-brewing process, representing approximately 85% of the total by-products obtained. This material is basically constituted by the barley grain husks obtained as solid residue after the wort production. Since BSG is rich in sugars and proteins, the main and quickest alternative for elimination of this industrial by-product has been as animal feed. However, BSG is a raw material of interest for application in different areas because of its low cost, large availability throughout the year and valuable chemical composition. In the last decade, many efforts have been directed towards the reuse of BSG, taking into account the incentive that has been given to recycle the wastes and by-products generated by industrial activities. Currently, many interesting and advantageous methods for application of BSG in foods, in energy production and in chemical and biotechnological processes have been reported. The present study presents and discusses the most recent perspectives for BSG application in such areas.
啤酒糟是啤酒酿造过程中产生的数量最多的副产品，约占所获副产品总量的85%。这种物质主要由麦芽汁生产后作为固体残渣得到的大麦谷壳构成。由于啤酒糟富含糖类和蛋白质，处理这种工业副产品的主要且最快捷的方式一直是用作动物饲料。然而，由于其成本低、全年供应量大且化学成分有价值，啤酒糟是一个在不同领域具有应用价值的原材料。在过去十年中，考虑到对工业活动产生的废物和副产品进行回收利用的激励措施，人们为啤酒糟的再利用付出了诸多努力。目前，已有许多关于啤酒糟在食品、能源生产以及化学和生物技术过程中应用的有趣且具有优势的方法被报道。本研究介绍并讨论了啤酒糟在这些领域应用的最新前景。
