1顶空-固相微萃取方法分析4种发酵剂制作馒头中挥发性风味物质显示文摘采用顶空-固相微萃取方法对传统老酵馒头与单一酵母馒头样品进行预处理,利用气相色谱-质谱法检测样品中的挥发性风味成分。经NIST 08.L质谱数据库检索结合文献对照,从旗舰馒头(传统老酵馒头)中检出59种挥发性风味成分,天津自制馒头(传统老酵馒头)中检出51种,安琪馒头(单一酵母馒头)中检出47种,燕山馒头(单一酵母馒头)中检出43种,这些挥发性成分中主要包括醇类、烃类、酯类、醛类、酮类、芳香类等。不同发酵剂制作馒头中风味物质的种类及相对含量都存在一定的差异性,这也是使用相同原料不同发酵方法制作馒头产生特别的风味的主要原因。马凯 华威 龚平 陈尔凝 白羽 刘杰 王衍生 李太华 高丽娟 2014食品科学2014,35,16:27
2Variation and trends in dough rheological properties and flour quality in 330 Chinese wheat varieties显示文摘The objective of this study was to investigate variation and trends in dough rheological properties and flour quality traits in 330 Chinese wheat varieties. The dough rheological properties of development time(DT), stability time(ST), and farinograph quality number(FQN)were evaluated, as well as the flour quality traits of protein(PC), wet gluten content(WGC), and sedimentation value(SV). The coefficients of variation of DT(40.5%), ST(58.1%), and FQN(42.4%) were higher than those of PC(9.1%), WGC(10.1%), and SV(15.3%). Normal distributions were observed for the flour quality indices but not for the rheological parameters. SV was strongly correlated with the three rheological parameters and accordingly might be used as a primary indicator for dough rheological property evaluation. Our results showed that there has been marked improvement in dough rheological properties for Chinese wheat varieties released since 1986, while flour quality has remained stable.Xiushi Yang Li Wu Zhihua Zhu Guixing Ren Sancai Liu 2014The Crop Journal2014,2,4:2
