Delphinidin Transition Indicator
Butterfly Pea Flower Lemonade
The brilliant color in this drink comes from delphinidin, a brightly-colored anthocyanin. Its color changes from blue in a neutral solution to red in acidic solution and yellow in basic. The lemon juice (pH = 2) in this drink creates a bilayer concoction that swirls to a beautiful purple—perfect for celebrating the transitions in your life!
