Quality Characteristics and Manufacture of Extruded Noodles Mixed with Cereals

Abstract We conducted this study to investigate the quality characteristics of extruded noodles(EN) mixed with cereals. The EN were evaluated for cooking properties(weight, water absorption, volume, and turbidity), Hunter`s color values, texture characteristics, and sensory characteristics. The cooked weight, water absorption, and volume of the cooked EN were significantly decreased relative to that of control noodles, whereas the turbidity increased. Hunter`s color L- and b-value of EN were decreased compare with the control noodles, but a-value was increased. Hunter`s color L-value of cooked EN was increased, whereas a- and b-value was increased. The texture characteristics(hardness, adhesiveness, springiness, gumminess, and chewiness) of the cooked EN-2 and EN-3 were similar to the cooked control noodles. A sensory characteristics (appearance, flavor, texture during mastication, taste, and overall quality) of EN-1 were significantly decreased relative to that of control noodles, but EN-2 and EN-3 was not different to control noodles. As the results of this study indicate that extrusion processing could be used to make the EN mixed with cereals. Key words: extrusion processing, noodles, cereal, quality characteristics
