Effects of potato starch on the properties of wheat dough and the quality of fresh noodles

Abstract

ABSTRACT The effects of potato starch on the pasting, rheological, and thermal properties of the dough, and the quality of the noodles were analyzed. The results showed that the addition of potato starch increased the pasting properties parameters of the dough, and increased the adhesiveness and hardness of the noodles; reduced the elastic and viscous modulus of the dough, and increased the springiness of the noodles; increased the freezable water content of the dough, decreased the semi-bound water content, and increased the water absorption of the noodles. The gluten network structure of the dough was destroyed, and the cooking loss and breaking rake of the noodles increased. The color and smoothness of the noodles were improved, the taste was worse. The quality of the noodles was acceptable when no more than 20% potato starch was added.
