中文摘要: 该文以品质特性相差较大的34 个小麦品种(系)为材料,采用偏最小二乘回归(partial least squares regression,PLSR)分析研究小麦粉的品质特性与生鲜面色泽、质构、感官特性的关系。结果表明,所试小麦粉的品质指标具有较大的变异系数(小麦粉b*值的变异系数为215.84%),样品具有较好的代表性;小麦粉L*值对生鲜面L*值具有显著性贡献(p<0.05),生鲜面L*值与蛋白质、湿面筋、干面筋含量、吸水率呈显著负相关(p<0.05);小麦粉的形成时间、稳定时间、粉质质量指数显著影响生鲜面的硬度指标(p<0.05);小麦粉的峰值黏度、最低黏度、最终黏度等与生鲜面的感官总分呈显著正相关(p<0.05),弱化度对其具有显著负影响(p<0.05)。结果表明,小麦粉的品质特性显著影响生鲜面的色泽、质构和感官特性,在生鲜面专用小麦品种优选中,需要综合统筹小麦粉色泽、糊化特性,以及面团筋力等因素的影响。
Abstract:In this study,34 wheat cultivars(varieties)were selected as materials to analyze the relationship between quality characteristics of wheat flour and color,texture and sensory properties of fresh wet noodles by the partial least squares regression(PLSR).Results showed that the quality indicators of the tested wheat flour had great coefficients of variation(the coefficient of variation of wheat flour's b*value was 215.84%),indicating ideal representativeness of the samples.Wheat flour's L*significantly contributed to the L*value of fresh wet noodles(p<0.05),while the L* value of fresh wet noodles had a significantly negative correlation with contents of protein,wet gluten and dry gluten as well as water absorption(p<0.05).The dough development time,dough stabilization time and farinograph quality index of wheat flour significantly affected the hardness index of fresh wet noodles(p<0.05).Wheat flour's peak viscosity,trough viscosity and final viscosity presented a significantly positive correlation with the total sensory score of fresh wet noodles(p<0.05),while dough's softening degree had a greatly negative effect on the total sensory score of fresh wet noodles(p<0.05).It was concluded that quality characteristics of wheat flour markedly affected color,texture and sensory properties of fresh wet noodles.It is necessary to consider the influences of wheat flour's color,pasting properties and dough strength when selecting special wheat varieties for fresh wet noodles.
