摘要: 为了解倒春寒对优质强筋小麦品种郑麦366加工和营养品质的影响,对6类(Ⅰ、Ⅱ、Ⅲ、Ⅳ、Ⅴ、Ⅵ类)不同冻害程度下郑麦366的品质指标进行检测和分析。结果表明,在加工品质方面,总体上粗蛋白含量、湿面筋含量、面团吸水率均随冻害程度加深而升高;而籽粒容重、面团稳定时间随冻害程度加深而降低,面粉的质量整体下降。在营养品质方面,总体上面粉蛋白质含量随冻害程度加深而升高;III和V类冻害程度下,直链淀粉含量相比对照显著降低,支链淀粉含量相比对照显著升高;Ⅲ、Ⅳ类的总淀粉含量,Ⅲ、Ⅴ类的直/支均较对照极显著降低。淀粉糊化特性分析结果表明,除Ⅳ类冻害外,峰值黏度、衰减值、最低黏度、最终黏度及回升值均随冻害程度的增加而降低,Ⅰ类和Ⅳ类冻害对糊化特性影响较大,糊化品质下降。

Abstract: In order to understand the effect of late spring coldness on processing and nutrient quality of high-quality strong gluten wheat Zhengmai 366,quality indexes of Zhengmai 366 with different degree of freezing damage were analyzed.The results showed that overall the crude protein content, wet gluten content and dough water absorption increased with the deepening of freezing damage; however,the volume weight and dough stability time decreased with the deepening of freezing damage,and the processing quality of flour decreased.For nutritional quality, the flour total protein content increased with the deepening of freezing damage;compared with the control,the amylose contents of Ⅲ,Ⅴ types of wheat significantly decreased,and amylopectin contents of Ⅲ,Ⅴ types of wheat significantly increased; the total starch contents of Ⅲ,Ⅳ types of wheat and ratios of amylose to amylopectin of Ⅲ,Ⅴ types of wheat significantly decreased compared with the control.The starch pasting properties results showed that the peak viscosity,trough viscosity,breakdown value,final viscosity and setback value decreased with the deepening of freezing damage except for Ⅳ type,Ⅰ and Ⅳ types of wheat had greater influence on the starch pasting properties,and the gelatinization quality decreased under late spring coldness.
