The results suggested that compared with A-starch and maize starch, there are more quantities of impurities, such as protein, lipid and pentosan, in B-starch. B-starch prepared in the laboratory almost has the same compositions as three samplings, and accords with the reports of some documents too. Differing from the granules in A-starch, those in B-starch are smaller sized (1-10m)and oval shaped, and felted each other. The crystallogram of A- and B-starch are similar, i.e. A type. There is difference in granular distribution between A- and B-starch. The granular distribution of B-starch is anomalous and extensive (l~1259m).B-starch has bigger dilatancy and retrogradation, and smaller blue value, solubility, viscosity, gelatinization temperature and gelatinization enthalpy.

试验结果表明：跟玉米淀粉、A淀粉相比较，B淀粉含有的蛋白质、脂肪和戊聚糖等杂质数量多；实验室制备的小麦B淀粉中淀粉、粗蛋白、戊聚糖等含量均与文献的报道接近，也与在工厂采样的B淀粉相近；与A淀粉不同，B淀粉以小颗粒的淀粉为主，平均粒径1～10μm，颗粒形状呈椭圆形，同时颗粒和颗粒之间黏结紧密；B淀粉和A淀粉晶形结构相似，都为A型；B淀粉的粒度分布情况不同于A淀粉，其粒度分布规律性不强，分布范围也较宽，粒度在1～1259μm之间；B淀粉的凝沉值和膨润力大于A淀粉，而沉降体积、蓝值、溶解度、粘度、糊透光度、相变温度和热焓均小于A淀粉；杂质的含量对B淀粉性质的影响是明显的，随着杂质含量的增加，沉降体积、溶解度和透光度减小，膨润力增大，但是它们对凝沉值、蓝值和粘度的影响比较复杂。

To use the abundant cytoplasm resources in wheat alien species to improve wheat quality, five wheat lines of Chris carrying different types of Aegilops cytoplasm were used to conduct the direct and reciprocal crosses with four wheat varieties, which were widely adopted in wheat production, and the effects of the five different types of Aegilops cytoplasms on pentosan contents in F1 kernels were stndied.

为了利用小麦近缘野生种属的细胞质资源改良小麦品质，以山羊草属不同种异源细胞质的5种异质小麦品种Chris为材料，与生产上广泛推广种植的4个常规小麦品种进行正反杂交，研究了异源细胞质对其F1籽粒戊聚糖含量的影响。

The amount of soluble pentosan of control doughs was a little more than that of the flour, and WEAX from control doughs was partly degraded.

未加酶面团较原料面粉中的可溶性戊聚糖含量略有增加，WEAX亦有部分降解，但作用程度远低于加酶样品。

戊聚糖酶使面团中可溶性戊聚糖含量比原料面粉中的显著增加；增溶速率最快的是在和面阶段；在上述的两个加酶水平下，面团中戊聚糖的增溶程度相当。

The amount of soluble pentosan of the doughs apparently increased with added enzyme, and was similar at the optimal and excessive levels of enzyme addition (120 μg/g), but the WEAX from the latter doughs was degraded to a greater degree.

加酶面团中可溶性戊聚糖含量显著增加，但加酶过量可导致面团中水可提取的阿拉伯木聚糖降解程度加剧。
