  • 摘要: 【目的】 筛选适合江苏种植的优质啤酒大麦品种。 【方法】 以扬州大学大麦研究所培育出的8份优异啤酒大麦品种为材料,测定其粒长、粒宽及千粒重等籽粒外观品质性状以及浸出物、α-氨基氮、糖化力、可溶性氮、蛋白质含量、库尔巴哈值等麦芽品质性状。 【结果】 参试品种籽粒品质均达国家优级标准;参试品种的浸出物含量以及库尔巴哈值均较低,麦芽蛋白质含量、α-氨基氮、糖化力含量均较高。 【结论】 扬农啤9号的综合啤麦品质最好,可作为江苏优质啤酒大麦原料生产品种。

     

    Abstract: 【Objective】 To identify high malt quality barley cultivars which is suitable for Jiangsu cultivation, grain quality and malt quality of eight Jiangsu malting barley cultivars were analyzed 【Method】 In this paper, with eight excellent beer barley varieties cultivated by the Barley Research Institute of Yangzhou University as materials, their grain length, grain width and one thousand grain weight, such as grain appearance and quality traits, extract, α-amino nitrogen, saccharifying ability, soluble nitrogen, malt protein content and Kolbach value, were determined. 【Result】 The results showed all these cultivars achieved national premium grade standard in grain quality; meanwhile, the eight barley cultivars showed lower find powder extract and Kolbach index, while on the contrary with higher malt protein content, α-amino nitrogen and saccharifying ability. 【Conclusion】 Yangnongpi 9 reveals high score, which can be used as production variety for high quality beer barley.
