摘要
分析了5个八倍体小偃麦中1、中2、中3、中4、中5和高蛋白优质小麦品种晋麦67的营养品质与几个主要的品质特性。结果表明,八倍体小偃麦的蛋白质、氨基酸、矿物元素均显著高于对照晋麦67,并且其加工品质较好,例如中2面团稳定时间达到17.2 min时,面包评分达90.5分,可制作优质面包,克服了营养品质提高,加工品质下降的矛盾。中1和中2具有1,7+8,5+10高分子量谷蛋白亚基,中3、中4、中5具有2*,7+9,5+10高分子量谷蛋白亚基。
In the study, we focadopted on characterization of the nutritional quality and major quality properties in the five octoploid trititrigia Zhong 1, Zhong 2, Zhong 3, Zhong 4, and Zhong 5. A newly developed wheat cuhivar with high protein content, Jinmai 67,was also included as the control group. The results demonstrated that protein, a- mino acid, and mineral element contents of these octoploid trititrigia accessions were significantly higher than that of the control without exception. Meanwhile,better processing quality was identified in the octoploid trititrigia lines. For instance, dough stabilizing time of Zhong 2 was 17.2 min and the score of proposed to be an appropriate option for producing high quality bread. Thq rior nutritional quality but also high processing quality. The compositions of high molecular weight glutenin subunits （ HMW - GS） of Zhong 1 and Zhong 2 were 1,7 ＋ 8, and 5 ＋ 10 ; and Zhong 3, Zhong 4, and Zhong 5,2 ＊ ,7 ＋ 9, and 5＋10.
