摘要
采用改进的面筋测定仪系统地研究小麦水不溶性戊聚糖对面筋形成及品质的影响。结果表明 :小麦水不溶性戊聚糖不仅降低面筋产率 ,而且影响面筋成分及品质。延长和面时间及增加和面加水量在很大程度上克服其对面筋产率的负作用 ,但不能完全消除其负作用。添加木聚糖酶可增加面筋产率 。
A modified glutomatic system was used to study the effect of water unextractable pentosans on gluten formation and properties. The results showed that water unextractable pentosans not only have a negative effect on gluten yield, but also affect gluten composition and properties. The negative effect of water unextractable pentosans on gluten yield could be compensated for to a large extent,but not completely, by increasing mixing time and mixing water. Adding xylanase can increase gluten yield and effectively improve gluten properties.
