This study was performed to evaluate the physicochemical and quality characteristics of dried noodles when different concentrations of Enteromorpha intenstinalis powder (EIP) were added to the wheat flour, thereby determining which noodle recipe was preferred. The cooking quality, mechanical texture properties, and viscosity of the prepared with noodles were measured, and then a sensory evaluation was conducted on them. The gelatinization points of the composite Enteromorpha intenstinalis powder-wheat flour were shown to have an increased viscosity at $95^{circ}C$ after 15 minutes. As measured via amylograph, the maximum viscosity values of those samples decreased with increasing EIP content. Also, when increased amounts of EIP were added, both the L and b values were reduced, whereas the a value was increased. The color values, weight and volume of the cooked noodles increased, as did the turbidity of the soup. With regard to the textural characteristics, the EIP additive increased hardness and reduced adhesiveness, cohesiveness and springiness. Overall, according to the results of our sensory evaluations, the noodles prepared with 5% EIP were preferred over other noodles.
