Butterfly Pea Flower Extract: A Plant-Based Blue Colorant for the Clean Label Era

As consumers worldwide increasingly seek healthier, more natural, and transparent food products, clean label ingredients have become a key driver of innovation in the food and beverage industry. In this clean-label era, butterfly pea flower extract offers brands a promising plant-based colorant that supports natural product positioning while meeting evolving consumer expectations.

Derived from the flowers of Clitoria ternatea, butterfly pea flower extract is a natural plant-based ingredient rich in anthocyanins, particularly ternatins, which contribute to its vibrant blue color. Beyond its characteristic blue hue, butterfly pea flower extract offers pH-responsive color transformation, creating shades ranging from blue and purple to pink and green for innovative product development. As a unique plant-based colorant, it has become an attractive alternative to synthetic food colors across a wide range of food and beverage applications.

Butterfly Pea Flower Extract: A Functional Ingredient Beyond Color

Antioxidant Potential of Natural Anthocyanins

Butterfly pea flowers are naturally rich in ternatin anthocyanins. Research has demonstrated that these plant-derived pigments exhibit significant free radical scavenging activity in in vitro antioxidant assays, including DPPH, ABTS, and FRAP, as well as antioxidant activity in cell-based studies^[1].

In addition, recent research suggests that butterfly pea is a promising natural source of antioxidants. Its bioactive compounds have been studied for their potential role in the prevention and management of oxidative stress-related chronic conditions, including diabetes, hypertension, and neurodegenerative diseases, and it has shown potential applications in functional foods, botanical products, and dietary supplements^[2].

For food manufacturers, the value of butterfly pea flower extract extends beyond natural coloring. It is not simply a colorant, but a functional pigment that combines visual appeal with added brand value.

Butterfly Pea Flower Extract: Global Regulatory Overview

Regulatory compliance is a key consideration when developing products with butterfly pea flower extract for different markets. Understanding local requirements for ingredient status, labeling, and permitted applications helps brands reduce compliance risks, improve product development efficiency, and support successful market entry.

United States

The U.S. Food and Drug Administration (FDA) has approved butterfly pea flower extract as a color additive exempt from certification for specified food categories. According to 21 CFR §73.69, butterfly pea flower extract is subject to specific requirements regarding product specifications and permitted food applications. Therefore, companies exporting to the U.S. market should ensure full compliance with these regulatory requirements^[3].

Southeast Asia

Butterfly pea has a long history of traditional culinary use in countries such as Thailand, Malaysia, Singapore, and Indonesia. It is widely used in beverages, desserts, rice dishes, and traditional foods as one of the region’s most recognized plant-based blue colorants. However, regulatory requirements still vary by country, and manufacturers should verify local compliance before market entry.

Europe and China: Regulatory Review Required

In the EU, Butterfly pea flower extract has not been authorized as a food color additive or included in the Union List of Novel Foods. In China, it is not listed in the permitted food additive standard (GB 2760) and has not been approved as a conventional food ingredient. Therefore, companies planning to commercialize butterfly pea flower extract in these markets should carefully evaluate the applicable regulatory requirements before market entry^[4].
