The Appropriate Way to Serve Butterfly Pea Flower Drink at Home

Abstract

This study conducted to find the appropriate way to serve butterfly pea flower drink at home. The colorless, red, purple, and green transparent glass and colorless glass covered by aluminum foil used to contain four grams butterfly pea petal. A 250 ml of boiling water poured to the glass to soak the petal for 60 minutes. The color intensity and total anthocyanin of the liquid measured every five minutes. The regression slope analysis exhibited that light gave no significant decrease in color intensity and total anthocyanin. About 83% of color and anthocyanin extracted within 5 minutes. There was no significant increase of the color and anthocyanin after 30 minutes. Therefore, the maceration of butterfly pea flower in boiling water for five minutes was appropriate to serve the drink. Furthermore, to reach the maximum color and anthocyanin content the 30 minutes maceration is needed. The maximum anthocyanin content of the drink was 19.57 ± 1.16 mg/l or equal to 1.22 ± 0.07 mg per gram fresh petal.
