Effects of wheat bran flour, oat flour, and <i>Dictyophora indusiata</i> powder on physical, chemical, sensorial, and <i>in vitro</i> digestibility of wheat noodles

Abstract Wheat bran, oat flour, and Dictyophora indusiata powder were used to substitute wheat flour in noodle production. The objective of this study was to investigate the effects of wheat bran flour, oat flour, and Dictyophora indusiata powder on physical, chemical, sensorial, and in vitro digestibility of wheat noodles. Results indicated that the addition of wheat bran flour, oat flour, and Dictyophora indusiata powder decreased the lightness, chewiness, and the reducing sugar released during digestion of noodles, and their estimated glycaemic index. The viscosity value of noodles decreased with Dictyophora indusiata powder addition solely. The protein, and dietary fibre of wheat noodle increased at 10% Dictyophora indusiata powder, and 10% oat flour blended with wheat flour, and the estimated glycaemic index lowered significantly with the addition of 10% wheat bran flour, and 10% Dictyophora indusiata powder.
