Abstract:
The effect of extruded brown rice flour (EBR) contents (0–50%) on antioxidant activity, phenolics, in vitro digestibility, color, and cooking quality of noodles containing mixtures of wheat and EBR was investigated. The antioxidant activity and phenolic content increased, especially ferulic and coumaric acids in bound forms, whereas the in vitro glycemic index, optimal cooking time, water absorption, hardness, and color were diminished in noodles with the addition of EBR; cooking loss increased as a function of the EBR percentage. The partial replacement of wheat flour with EBR can be favorably used in the wheat noodle formulation. The results provide the basis for the development of staple foods with nutritional characteristics for today’s functional food markets.
