THE CORRELATION BETWEEN GLUTEN PROTEIN COMPOSITION AND RHEOLOGICAL PROPERTIES OF WHEAT DOUGH
摘要
Abstract
This research investigated the relationship of mixing time and rheological properties on three different wheat flour systems: bread-flour, multiple wheat flour and cake flour selected according to their baking performance. The results showed the dough of strong and moderately strong wheat cultivars required a longer mixing time (4~5 min) than weak cultivars (2~3 min). Doughs from strong cultivars exhibited higher storage modulus (G') and lower tanδ values at all frequencies compared to moderately strong and weak cultivars in small strain rheological measurements. The relaxation behaviour was measured for gluten and its subtractions, i.e. gliadin, soluble glutenin and gel protein's relaxation properties. The result showed gel protein and glutenin had higher (G') storage modulus and longer relaxation time compared with that of gliadin, which indicated gel and glutenin having larger molecular weight (MW) than that of gliadin.关键词
