【摘要】 采用2个面筋强度不同的冬小麦品种为材料,在其籽粒灌浆的不同时期(开花后15天、20天和25天)进行适度高温?日平均温度<32℃,未达到热胁迫水平)处理,研究了不同处理条件下对小麦蛋白组分、面粉品质和面条加工品质的影响。结果表明:适度高温处理对不同筋力小麦醇溶蛋白的影响趋势一致,但对谷蛋白的影响却有较大差异;不同筋力小麦的蛋白组分对适度高温处理的反应不同;适度高温处理对筋力强的小麦淀粉品质的影响程度优于筋力弱的小麦;小麦开花后20天时适度高温处理利于优质面团品质的形成;适度高温处理利于面条的弹性和面条评分,不同处理间的影响程度不同。更多还原

【Abstract】 Two winter wheat cultivars with different gluten strength were used to study the influence of moderate high temperature(average daily temperature lower than 32℃) during grain filling stages(15 days,20 days and 25 days after anthesis) on protein compositions,flour quality and noodle quality.The results indicate that the effects of the temperature treatments on gliadins of the cultivars with different gluten strength are at the same trend,while the effects on the glutenins are different,and the effects on the starch quality of the cultivars with strong gluten strength are superior to those with weak gluten strength.The moderate high temperature during 20 days after anthesis avails for development of good dough quality.The moderate high temperature treatments are also benefit for noodle spring and noodle score,although the affected degree are different.更多还原
