Quality improvement effects of electrolyzed water on rice noodles prepared with semidry-milled rice flours.

To investigate the effects of electrolyzed water treatment on the qualities of rice noodles prepared with semidry- milled rice flour, pasting properties and thermal properties of rice flour, and the cooking and textural properties of rice noodles were determined. Higher peak viscosity and lower melting enthalpy were observed in electrolyzed water (EW) treated rice flour. The hardness, gumminess and chewiness of rice noodle in slightly acidic electrolyzed water treated rice noodles with available chlorine concentration (ACC) 20.32 mg/L were increased significantly (p < 0.05). The cooking loss decreased significantly in strong acidic electrolyzed water treated noodles with ACC 10.09 mg/L treatment (p < 0.05). The results indicated that EW could promote the gelatinization of rice flour, and improve the textural qualities of rice noodles. Therefore EW was appropriate to be used in rice noodle production. © The Korean Society of Food Science and Technology 2021.
