Noodles promote health as a source of essential nutrients and fiber. This study evaluated the effects of incorporating various levels of betel leaf extract on the quality and sensory acceptability of Hokkien noodles. Hokkien noodles incorporated with betel leaf extract (0, 5, 10, 15, and 20% based on flour weight) were prepared from wheat flour with a moisture content of 14%. The hardness, elongation, adhesiveness, color, and sensory evaluation of the noodles were then determined. Results clearly show that the incorporation of betel leaf extract at various levels led to the structural modification of the noodles and to a soft product compare to the control. However, the product scores in all sensory attributes were higher than the control scores. The sample was incorporated 15% betel leaf extract had the best acceptance quality wherein the beneficial effects of betel leaf polyphenols can be utilized.
