摘要: 摘 要:该研究将一定比例的全麦粉添加到精粉中,制成油馕面团,利用专业面粉仪器设备研究全麦粉的添加量对油馕面团结构、粉质、拉伸以及糊化等特性的影响。当全麦粉完全取代精粉时面团吸水率、形成时间分别提高了15.12%、29.30%,稳定时间、弱化度和质量指数则分别下降了28.32%、34.98%、18.53%;拉伸能量由87cm2降低到30 cm2,延展度由156 mm降低到92 mm,拉伸阻力由302 EU降低到242 EU,全麦粉的添加对面团的加工特性造成不良的影响;全麦粉的添加导致面团峰值粘度显著下降,谷值粘度、衰减值、回升值也有类似的现象,全麦粉的加入会改变混合粉的溶剂保留率,SRC的变化说明全麦粉中破损淀粉、戊聚糖水平较高麦谷蛋白水平较低;当全麦粉完全取代精粉时,α-螺旋和β-折叠的总含量由68.6%下降为50.9%,无规则卷曲含量增加了31.5%,面筋蛋白稳定性变差。

Abstract: Abstract:In this study, a certain proportion of whole wheat flour was added to the refined flour to make naan dough, and the effects of the addition amount of whole wheat flour on the structure, flour quality, stretching and gelatinization of naan dough were studied by using professional flour equipment. The water absorption and formation time of dough were increased by 15.12% and 29.30%, respectively, while the stability time, weakening degree and quality index were decreased by 28.32%, 34.98% and 18.53%, respectively. The tensile energy decreased from 87cm2 to 30 cm2, the elongation decreased from 156 mm to 92 mm, and the tensile resistance decreased from 302 EU to 242 EU. The addition of whole wheat flour had adverse effects on the processing characteristics of dough. Graham added to the dough a significant reduction in the peak viscosity, valley viscosity value appreciation, attenuation value, back has a similar phenomenon, whole wheat powder mixed with change of solvent retention rate,whole wheat flour with the SRC changes of higher levels of damaged starch, pentosan glutenin level is low; When the whole wheat flour completely replaced the refined flour, the total content of α -helix and β -fold decreased from 68.6% to 50.9%, the random curl content increased by 31.5%, and the gluten stability became worse.

Key words: whole wheat flour, oil naan, dough, gelatinizing properties, tensile properties
