摘　　要：为了研究不同系统面粉沉降值分布规律以及Zeleny沉降值和SDS沉降值之间的相关性,从面粉厂不同系统中取粉,得到不同系统面粉,对不同系统面粉的两种沉降值分别进行了测定.研究发现:不同系统面粉Zeleny沉降值和SDS沉降值之间变化没有规律性;不同系统粉中,Zeleny沉降值和SDS沉降值之间不具有线性相关关系.另外,为了研究Zeleny沉降值和SDS沉降值与系统粉面筋含量之间的关系,对不同系统面粉的湿面筋和干面筋含量进行了测定,并就Zeleny沉降值和SDS沉降值与湿面筋含量之间的相关性分别进行了分析,研究发现不同系统粉中,Zeleny沉降值、SDS沉降值与湿面筋含量之间不具有线性相关关系.因此对于本研究的制粉系统而言,沉降值不能够很好地反映系统粉品质的质量.A serious of wheat milling streams were obtained from wheat flour mill. The Zeleny and SDS sedimentation value of different milling streams were determined in order to ivestigate the distribution and the correlation between Zeleny and SDS sedimentation value. Th＇e results showed that the distribution of Zeleny and SDS sedimentation value in different milling streams had no regularity, and also showed that Zeleny and SDS sedimentation value in different milling streams had no linear correlation. In order to further investigate the correlation between sedimentation value and gluten content, the wet and dry gluten content of different milling streams were determined. The results indicated that whether Zeleny or SDS sedimentation value had not linear correlation with wet gluten content. It was concluded that Zeleny or SDS sedimentation value was not a good index for the quality evaluating of wheat milling streams.
