| In order to explore the influence of different thermal treatments of millet flour on the wheat dough quality,the millet flour were processed by inflating,steaming and stir-frying,respectively. The steamed millet flour and stir-fried millet flour were added to the wheat flour according to the proportion of 0,5%,10%,15%,20%,25%,30% and 35%,while the inflating millet flour was added to the wheat flour according to the proportion of 0,2%,4%,6% and 8%. The rheological property of the mixed flour dough was investigated. The results showed that,under different thermal treatments,the ash,protein,fat,total starch and total dietary fiber content of millet flour were decreased; but the soluble dietary fiber was increased(except stir-fried group).The farinographical properties and tensile properties were significantly different(P<0.05) among different millet flour content in each group,and the farinographical properties were weakened with the increase of millet flour content,the farinographical properties in steaming group and stir-frying group were better. With the increase of millet flour content in each group,the tensile properties of the inflating group were enhanced first and weakened latter,but those in steaming group and stir-frying group were weakened,and the tensile properties of three groups were enhanced with the extension of fermentation. However,the tensile properties were not quite different among different treatments. |
