2、时间面条色泽之间的关系,及其与小麦品种品质性状的关系。结果显示,鲜面条恒温(25℃)放置24h后,面条色泽L*值显著下降,a*值和b*值显著升高;0h面条色泽L*值、a*值、b*值与24h面条色泽均呈极显著正相关(P<0.01),鲜面条色泽可以预测放置后面条的色泽。逐步回归分析结果表明,籽粒容重、蛋白质含量、湿面筋含量、面粉色泽L*值、弱化度等决定面条色泽L*值57.5%的变异;面粉色泽b*值、拉伸阻力决定面条色泽b*值51.1%的变异。面粉色泽与鲜面条色泽呈正相关关系。籽粒蛋白质含量、湿面筋含量与鲜面条色泽L*值呈负相关关系。面粉色泽、籽粒蛋白质含
3、量、湿面筋含量是影响面条色泽的主要品质性状。关键词:小麦;面粉;面条色泽;品质性状;相关性中图分类号:S512.1;S331文献标识码:A文章编号:1009-1041(2012)02-0344-05TheRelationshipbetweenNoodleColorandKernelQualityPropertyofWheat1,2,ZHANGBo1,WEIYi-min1,DONGKai-na3,ZHANGXiao-ke2ZHANGYing-quan(1.InstituteofAgro-productsProcessingScienceandTechn
