Abstract The assessment of malting barley to determine if it meets grain quality requirements is an integral step in ensuring an efficient malting process and a good quality malt output. Specific weight (SW) is an industry standard criterion, however links between SW and malting are not well understood. In this study the effect of a changing SW on malting was investigated. Samples were manipulated according to both grain size and weight, creating grain fractions with a range in SW. Prior to malting, grain quality traits were measured, and after malting, malt quality traits were examined. Increased SW resulted in a reduced number of whole, unmodified corns in malt, implying increased levels of modification. Specific weight correlated with both hot water malt extract (r = 0.82, P

春大麦比重与麦芽品质的关系

摘要 对麦芽大麦进行评估以确定其是否满足谷物质量要求是确保高效麦芽过程和优质麦芽产量的一个不可或缺的步骤。比重 (SW) 是一项行业标准，但 SW 与麦芽制造之间的联系尚不清楚。在这项研究中，研究了改变 SW 对麦芽制造的影响。根据颗粒大小和重量处理样品，产生 SW 范围内的颗粒部分。在发芽前，测量谷物质量性状，在发芽后，检查麦芽质量性状。增加的 SW 导致麦芽中完整的、未改性的玉米数量减少，这意味着改性水平的提高。比重与两种热水麦芽提取物相关（r = 0.82，P
