中文摘要:

为了解不同分子量蛋白质对小麦品质及馒头加工品质的影响，以石优17、石4366、石麦15等30个石麦系列小麦品种为材料，对不同分子量蛋白质相对含量、品质特性以及馒头加工品质进行了检测与分析。结果表明，UPP（SDS不溶性蛋白大聚体）、LPP（大分子量聚合体蛋白）、LMP（大分子量单体蛋白）的相对含量及LPP/LMP比值与小麦粉的大多数品质指标存在显著或极显著相关性；不同分子量蛋白质相对含量较蛋白质含量更能反映小麦品质；UPP相对含量可作为小麦粉品质性状及面筋特性的预测和评价指标。蛋白质含量显著影响馒头的粘着性，UPP、LPP、LMP相对含量及LPP/LMP比值主要影响馒头质构特性中的硬度、胶着性及咀嚼度。UPP相对含量可以作为评估小麦粉是否适宜馒头加工的重要指标。

英文摘要:

In order to study the effects of different molecular weight wheat proteins on wheat quality and processing quality of steamed bread, the relative contents of wheat protein with different molecular weight, wheat flour quality characteristics and steamed bread processing quality of 30 Shimai series wheat varieties, such as Shiyou 17, Shi 4366 and Shimai 15, were systematically detected and analyzed. The results showed that the relative contents of UPP (SDS-insoluble polymeric protein), LPP (large polymeric protein), LMP (large monomeric protein) and the ratio of LPP/LMP were significantly correlated with most of the quality characteristics of wheat flour. The relative contents of wheat proteins with different molecular weight can reflect the quality of wheat other than the content of grain protein. The relative content of UPP can be used as a prediction and evaluation index for the quality traits of wheat flour and the characteristics of gluten. The content of wheat protein significantly affected the adhesiveness of steamed bread. The relative contents of UPP, LPP, LMP, and the ratio of LPP/LMP mainly affect the hardness, gumminess, and chewiness of steamed bread. The relative content of UPP can be also used as an important index to evaluate whether wheat flour is suitable for processing steamed bread.
