Recently, the US Food and Drug Administration (FDA) approved the water extract of butterfly pea flower (Clitoria ternatea) as a natural blue pigment additive, which is a plant native to Southeast Asia. This time, the approval of the US FDA regulations is regarded as a "milestone" breakthrough point, because the approval of pigment additives is like "rare birds" and does not happen often.
The butterfly pea flower is a very popular ingredient in Southeast Asia, and it has also gained a lot of attention on social platforms in the past two years. The butterfly pea flower, also known as the blue butterfly, is a natural antioxidant plant rich in vitamins A, C, and E. People in Southeast Asian countries often use dried flowers to make tea, and the tea is blue. This is because butterfly pea flowers contain a lot of natural anthocyanins, which can be used as natural food coloring agents or cocktails. This kind of pigment is commonly used in Southeast Asia to make blue.
