Roasted Liriopis tuber powder (LTP) was added in different amounts based on wheat flour (1%, 3%, 5%, 7% and 9%). Cooked noodles containing LTP exhibitedsignificantly lower values for weight, volume, and water absorption; in contrast, higher values were exhibited for turbidity. The Hunter L value (for lightness) of uncooked and cooked noodles decreased but the a value (for redness) and b value (for yellowness) increased with the addition of Liriopis tuber. Textural properties (springiness, cohesiveness, chewiness, and brittleness) measured with a texture analyzer significantly decreased with the addition of Liriopis tuber. From the sensory evaluation results, noodle containing 7% Liriopis tuber was considered the best. To improve the quality of noodle containing 7% LTP, activated gluten was added at different percentages of flour (1%, 2%, 3%, 4% and 5%). Cooked noodles containing activated gluten exhibited significantly higher values for weight, volume, and water absorption; in contrast, lower values for turbidity were exhibited. In addition, the textural properties significantly increased with the addition of activated gluten. From the sensory evaluation results, noodle containing 3% activated gluten was considered the best. In conclusion, noodle with 7% LTP and 3% activated gluten exhibited the most desirable qualities. 收起
