Valorization of brewer's spent grain and Canadian beer through the identification of antioxidant characteristics

啤酒是加拿大最受欢迎的酒精饮料，可能是天然抗氧化剂的主要来源，对各种啤酒及其啤酒花中这些内源性营养素和抗氧化剂的研究可以使加拿大啤酒成为具有国际竞争力和市场优势的产品。加拿大麦芽技术中心（CMBTC）评估加拿大麦芽在麦芽和酿造过程中的质量，模拟商业规模生产，为麦芽和酿造行业提供解决方案。为了具有竞争力，相对较小的加拿大酿酒商和酒商必须推出创新产品，或者不断提高和突出其现有产品的价值。本项目旨在为CMBTC生产的啤酒提供详细的定量抗氧化剂信息和活性，并与商业民族品牌进行比较，为公司提供竞争优势、增值、产品开发和创新的重要工具。利用该项目产生的知识，CMBTC将能够帮助酿酒商开发新的啤酒产品；并从废弃的谷物中获得额外的价值，这些谷物目前作为动物饲料出售，利润率很低，通过它来生产有益健康的产品。酚类化合物分析的专业知识将由曼尼托巴大学的usha Thiyam-Hollander博士提供。

As beer is the most popular alcoholic beverage in Canada and likely the major source of natural antioxidants,the investigation of these endogenous nutrients and antioxidants from various beers and their hops could bringCanadian beer forward as an internationally-competitive product with market advantage. The Canadian MaltingBarley Technical Centre (CMBTC) evaluate the quality of Canadian malting barley in the malting and brewingprocesses, simulating commercial scale production, delivering solutions to malt and brewing industries. To becompetitive, the relatively smaller Canadian-owned brewers and maltsters must come up with innovativeproducts or consistently enhance and highlight the values of their existing products. The present project aims toprovide detailed quantitative antioxidant profile information and activities of beers produced by the CMBTC incomparison with commercial national brands, providing the company with vital tools for competitiveadvantage, value addition, and product development and innovation. Using the knowledge generated from thisproject, the CMBTC will be able to help brewers develop new beer products; and obtain additional value fromthe spent grain, which is currently sold as animal feed that sells for a very low profit margin, by producinghealth benefits products from it. The expertise for analysis of phenolic compounds will be provided by Dr.Usha Thiyam-Hollander at the University of Manitoba.
