摘要近年来,育种工作者已经越来越关注种质资源的收集、鉴定及遗传评价利用。在市场经济条件下,大麦品种的品质性状成为影响其经济价值的重要性状。若大麦籽粒中的蛋白质含量低于20%的话,我们就把这一类选为低蛋白含量大麦籽粒。大麦籽粒中蛋白质含量的高低也影响这它的用途。其中,饲用大麦的蛋白质含量一般要求大于13%,啤用大麦的籽粒蛋白质含量在9%~12%之间则最为适宜。欧洲酿造协会对大麦籽粒蛋白质含量要求不超过11.5%。因此,本实验主要将126份大麦品系籽粒打磨成粉,提取出其中的蛋白质,通过酶标仪法来测定大麦籽粒中蛋白质的含量,整理实验数据。通过实验数据发现,用于本次实验的大麦籽粒种类中,属于低蛋大麦籽粒共有81中,其中适合用于啤酒酿造的大麦籽粒一种有17种。同时,讨论了在低蛋白含量的大麦籽粒中,若用于啤酒酿造的大麦籽粒中的蛋白质含量超过最适宜值,则对啤酒有何影响;若大麦籽粒蛋白质含量低于最适宜值,同样对啤酒酿造有何影响。60575
Abstract In recent years, breeders have been increasingly concerned about the collection, identification and evaluation of the use of genetic germplasm. In a market economy, quality traits in barley varieties become important traits affecting their economic value. If the barley grain protein content of less than 20%,We will put this kind preferably low-protein barley grain。 Barley grain protein content also affects the level that it uses. Wherein the protein content of feed barley generally require more than 13.0%,beer barley grain protein content of between 9.0% to 12.0%, the most appropriate. The European Association for brewing barley grain protein content requirement of no more than 11.5%. Therefore, this experiment will be 126 parts barley grain ground into flour, finishing the experimental data。Experimental data found,for barley grain species in this experiment,a low-protein barley total of 81 kinds of grain,which it is suitable for grain barley beer brewing one 17 species。Simultaneously,It discusses barley grain protein content in low, If the barley grain used in beer brewing in the protein content of more than the optimum value,the impact on beer;If the barley grain protein content lower than the optimum value,also the impact on the beer brewing。
