Formula and Quality Study of Multigrain Noodles

Abstract

Multigrain noodles were made by com and wheat flour as the main ingredients and with small ratios of oat flour, soybean flour and millet flour through extrusion process. Simplex centroid design was used to analyze gelatinization characteristics of the mixed flour, rheological characteristics of the doughs, cooking qualities and sensory qualities of noodles. A proper formula for multigrain noodles obtained as outcome: 45% com flour, 40% wheat flour, 4% oat flour, 11% millet flour. Compared to the wheat noodles, the multigrain noodles had higher content in fat, dietary fiber and total resistant starch, but it did content less proteins than wheat noodles.Supported by National Natural Science Foundation of China (31401642).
