摘　　要：为提高纯苦荞挂面的加工适应性及面条品质,将挤压处理后的苦荞粉与生苦荞粉混合后制作纯苦荞挂面,将挤压苦荞粉的添加量及和面加水量结合探究其对纯苦荞挂面加工品质及面条品质的影响。通过面带的质构品质、面条的蒸煮及质构特性评价纯苦荞挂面的加工性能和食用品质。结果表明,随着挤压苦荞粉添加量的增加,面带的表面黏附力和抗拉伸力及面条的蒸煮损失率显著(P<0.05)增加;随着和面加水量的增加,面带的表面黏附力显著(P<0.05)增加,抗拉伸力下降,面条的硬度、咀嚼性和蒸煮损失率均显著(P<0.05)增加,当挤压苦荞粉的添加量为30%,加水量为34%时,面带的表面黏附力最低,抗拉伸力适中,蒸煮损失率最小,质构品质较好,综合评价最高。In order to improve the processing adaptability and noodle quality of the whole tartary buckwheat noodles,the extruded tartary buckwheat flour was mixed with raw tartary buckwheat flour to make the whole tartary buckwheat noodles.The effects of the amount of extruded tartary buckwheat flour added and the amount of water added in dough mixing process on the processing and noodle quality of the whole tartary buckwheat noodles were explored.The textural property of dough sheet,and cooking quality,and textural property of cooked noodles were used for the evaluation indexes.The results showed that with the increase amount of extruded tartary buckwheat flour,the surface stickiness and tensile strength of the dough sheet and the cooking loss of cooked noodles increased significantly(P<0.05).Meanwhile,with the amount of water increased,the surface stickiness of the dough sheet increased significantly(P<0.05).But the tensile strength decreased,and the hardness,chewiness and cooking loss rate of noodles increased significantly(P<0.05).After optimization,the dough sheet had the lowest stickiness and appropriate tensile strength,and the whole tartary buckwheat noodles had the lowest cooking loss and appropriate textural property when 30%of extruded tartary buckwheat flour and 34%amount of water was added.
