Butterfly pea flower - India's natural blue colourant for beverages & dairy

AltSugar™ Butterfly Pea Flower is derived from the dried blossoms of Clitoria ternatea — a flowering vine native to Southeast Asia that grows abundantly across Tamil Nadu and Kerala in India. For centuries, this deep-blue flower has been used in Ayurvedic tradition as a brain tonic, a natural dye, and a wellness herb. Today, it is one of the most sought-after functional ingredients in global food and beverage innovation.

What makes butterfly pea flower scientifically extraordinary is the anthocyanin class it contains — called ternatins — which give it an intensely vivid blue colour that responds to pH. Add an acid (lemon juice, lime, citric acid) and the colour transforms in real time: blue shifts to violet, then purple, then magenta pink. No synthetic colourant can produce this effect. No other natural ingredient does it either. Beyond colour, butterfly pea flower carries a growing body of scientific research supporting antioxidant, antidiabetic, anti-inflammatory, and nootropic properties — making it a dual-value ingredient for both clean-label colour and functional health applications.
