Anthocyanins 101

What are Anthocyanins?

Anthocyanin is an umbrella term for a group of pigments that are primarily found in fruits and vegetables. Every type of anthocyanin has a different shade which changes according to the pH of the applications it’s used in.

Anthocyanins are best suited to low pH applications, giving off a variety of shades. We don’t recommend using anthocyanins above pH 4.2 as the colour won’t be as stable, and may fade over time.

Anthocyanins are extracted from Black Carrot, Radish, Red Cabbage, Purple Sweet Potato, Elderberry and Grape Skin. And deliver rich food colours from vibrant pinks, reds, and purples.

How are anthocyanins produced?

Anthocyanins are produced by selectively extracting the pigment from the relevant fruit or vegetable required. Plant-Ex then processes this pigment, using emulsifiers, stabilisers and carriers, giving the desired concentration and shade, producing either a liquid food colour or a powder food colour for customers.

Are they heat or light stable?

Anthocyanins are heat stable and light stable. However, they are only suited to acidic pH.

In which applications are they mostly used?

Plant-Ex recommends using anthocyanins in acidic pH. They perform very well in beverages and confectionery, and we have achieved some great shades in our applications kitchen when baked, such as our Sweet Potato Extract Powder pictured left.
