California Natural Color, a supplier of grape juice concentrates, natural colors, and grape seed extracts, has expanded its portfolio with the introduction of the pure purple butterfly pea flower. Native to Thailand, this plant’s flavorless and odorless leaves make it an ideal component for natural coloring. This new product offers an alternative to spirulina, previously provided to formulators and developers as a blue food coloring solution. Spirulina, a blue-green algae rich in vitamins, minerals, and protein, struggles with certain pH levels, making it challenging to work with. Butterfly pea flower uniquely provides vibrant purple hues in applications below pH 4 and blue tones above pH 4.
