研究了玉米、小麦和混合谷物干酒糟与可溶物（DDGS）的成分变异性，DDGS来源、乙醇植物以及玉米与相应DOGS之间的关系。共138个DDGS样品进行了分析，通过使用近红外反射光谱的共同成分，而63个DOGS样品沿着和11个玉米样品的非淀粉多糖（NSP）的含量进行了表征。结果表明，DOGS的组成曲线反映了亲本谷物的营养成分，但在淀粉发酵成乙醇后，剩余营养成分（例如蛋白质、脂肪、纤维和矿物质）的含量更高。玉米DDGS与小麦DDGS的差异在于脂肪含量较高（P
Corn-, wheat- and mixed cereal Distillers' Dried Grains with Solubles (DDGS) were investigated for compositional variability among DDGS origins, ethanol plants, and the relationship between corn and corresponding DOGS. A total of 138 DDGS samples were analyzed by use of Near Infrared Reflectance Spectroscopy for common constituents, while 63 DOGS samples along with 11 corn samples were characterized for their non-starch polysaccharide (NSP) content. The results indicated that the compositional profile of DOGS reflected the nutrient content of the parent grain but with a greater content of remaining nutrients (e.g. protein, fat, fibre and minerals) after fermentation of starch to ethanol. Corn DDGS differentiated from wheat DDGS by a greater content of fat (P
