Effect of Compositional Variation of Gluten Proteins and Rheological Characteristics of Wheat Flour on the Textural Quality of White Salted Noodles

Protein quality parameters of wheat flour, as well as protein content, showed significant relationship with hardness, cohesiveness, springiness, adhesiveness, chewiness, and gumminess of the cooked noodles. A significant positive correlation (0.54) was observed between glutenins and hardness of noodles. Chewiness of the noodles increased with the protein content, sodium dodecyl sulfate sedimentation volume, dough development time, dough stability, and glutenins. Hardness, springiness, cohesiveness, gumminess, and chewiness of the noodles were negatively affected by gliadin to glutenin ratio. Multiple regression analysis depicted significant relationships of the various noodle quality parameters with wheat flour characteristics. The results revealed that the relative composition of the gliadins and glutenins had a considerable effect on the textural profile of noodles indicating their defining contribution on the noodle quality. The resulting information could be useful in predicting the noodle-quality potential of the varieties.
