2004—2011年中国主产省小麦蛋白质品质分析

Analysis of Wheat Protein Quality in Main Wheat Producing Areas of China from 2004 to 2011

【目的】分析2004—2011年来中国主产区小麦蛋白质品质检测数据,探讨小麦蛋白质品质年度和地区间变化规律。【方法】对2004—2011年分别来自冀、鲁、豫、苏、皖5个小麦主产省的4 235份小麦样品的籽粒蛋白质含量、湿面筋含量、沉淀值、稳定时间和最大拉伸阻力进行分析。【结果】2004—2011年,中国主产省小麦籽粒蛋白质含量和湿面筋含量平均值变化不大,沉淀值呈明显下降趋势,表明近年来小麦内在品质变差;不同主产省之间小麦蛋白质含量差异较大,呈明显北高南低和东高西低趋势。【结论】近年来片面追求高产已影响了中国小麦的整体品质,致使强筋麦产区小麦面筋强度降低、弱筋麦产区小麦面筋增加。应根据各地区的不同条件发展适合本地区的高产优质小麦品种。

【Objective】In order to understand wheat protein quality status in China in recent years,wheat protein quality in different years and regions was discussed.【Method】 A total of 4 235 wheat samples collected from the main wheat provinces during 2004-2011 were analyzed for protein content,wet gluten content and sedimentation value,stable time and maximum resistance.【Result】The protein content and wet gluten content had no obvious change,however,sedimentation value declined slightly from 2004 to 2011;The protein quality in different main wheat provinces was quite different,higher in the north and east places.【Conclusion】Results showed that emphasis of wheat production on yield has affected the overall quality of wheat seriously in China.Development of high yield wheat varieties with high quality should be focused according to the conditions in different areas.
