Butterfly pea (Clitoria ternatea) (CT), a climbing ornamental plant, is widely distributed in tropical zones such as Asia and Central and South America, and its edible flowers have been used in foods, drinks, and deserts as a natural colorant (Gamage et al., 2021). CT flower is rich in phytochemicals including anthocyanins, flavonols, and phenolic acids, and its extracts possess antidiabetic, antioxidative, anti-inflammatory, and antimicrobial properties (Escher et al., 2020;

Clitoria ternatea (CT) flowers are rich in phytochemicals. An innovative approach was taken to utilize CT flower extract (CTFE) as a functional ingredient with natural pigment by incorporating it into noodles. The aim of this study was to examine the effect of the CTFE amount (0–30%) on the color, texture, phytochemicals, and sensory quality of both dried and cooked noodles. Dried noodles with 30% CTFE had the highest total anthocyanins (9.48 μg/g), polyphenols (612 μg/g), DPPH radical scavenging capacity (165 μg TE/g), and reducing power (2203 μg TE/g). Cooking resulted in a significant decrease in the anthocyanin levels and blue color, while also increasing the greenness of the noodle. Both dried and cooked noodles with 20–30% CTFE showed a significantly higher color preference compared to the control sample. Despite a significant reduction in the cutting force, tensile strength, and extensibility of cooked noodles with 20–30% CTFE, the sensory attributes such as flavor, texture, and overall preferences were similar to those of noodles with 0–30% CTFE. Blue noodles with high phytochemicals, antioxidant activities, and desirable sensory qualities can be produced by the incorporation of 20–30% CTFE.
