1、中国干白面条品质评价方法研究(1西华大学生物工程学院,成都610039:2中国农业科学院作物育种栽培研究所/国家小麦改良屮心,北京100081;3CIMMYT屮国办事处,北京100081)摘要:以16个品质差异较大的小麦品种(系)为材料,研究籽粒和面粉特性对面条品质的影响,用色度仪和质构仪分别测泄面粉与面条的颜色及面条质地特性,按商业部1993年标准对面条品质进行感官评价。结果表明,面条的外观品质和质地结构是籽粒破度、面粉灰分、蛋白质含量和质量及淀粉特性综合作用的结果。用色度仪代替人为感官评价对煮熟面条颜色
2、进行定呈测定,二者的相关系数为0.73o质构仪TPA指标硬度能较好反映面条表观状态、适口性、韧性和总分,相关系数分别为0.54、0.70、0.56和0.66,达5%或1%显著水平;胶着性也能较好反映而条表观状态、适口性和总分,z•为0.56s0.66和0.59,达5%或1%显著水平;弹性则与而条粘性呈显著负相关,口-0.61。因此,用质构仪定量测定面条软硬度和胶着性,有助于客观评价面条的表观状态、适口性和总分。关键词:普通小麦;面条品质;色度仪;质构仪;感官评价MethodsforEvaluationofQ
