10 uses of natural colour sources

Anthocyanins are the mysterious pigments that give flowers, berries, leaves and fruits their bright red, purple or blue colours. They act as natural shields against UV radiation, cold and predators, influence the attraction of pollinators and may be nutritionally relevant. But what surprising abilities do they really hide?
  • Pay attention to colour depth

Deliberately choose deep-red, purple and blue fruits and vegetables. Intense colour is often a reliable clue to a high anthocyanin content. This simple shopping tip saves you from having to study nutrition tables.

  • Use red cabbage in many ways

  • Aronia juice as a quick substitute

If you’re short on time, drink a small glass of aronia juice (e.g. 200 ml). Aronia is among the top sources of anthocyanins and therefore makes a practical daily portion. If needed, you can mix the juice with orange juice to mellow the taste.

  • The hue of anthocyanins reveals the pH state, because it shows a colour change that depends on the amount of acidity. Thus a shift from red to purple or from purple to bluish is possible, depending on whether the pH is acidic, neutral or alkaline. That is why red cabbage changes colour when vinegar or baking soda is added.
  • The anthocyanin group is large – around 250 different compounds have been described, which contributes to the wide palette of colours and bioactive properties.
  • How many anthocyanins a plant produces depends on the species or variety, the stage of development and external factors such as light, temperature, water and soil quality. Stress can additionally stimulate production.
  • There is no official recommended daily intake for anthocyanins. Experts nevertheless recommend regularly including anthocyanin-rich foods in the diet.
