Mixed carotenoids from algae source > for food, dietary supplements and beverages

Carotenoids are plant pigments with a colour spectrum of yellow to orange and red. Mainly they appear in the chromoplasts of the plants. Animals are not able to synthesize carotenoids.
The carotenoids are divided into two groups: the carotenes (hydrocarbons) and the xanthophylls (oxygenated derivates of the hydrocarbons). The Xantophylls are responsible for the yellow colouration of leaves in autumn.
Naturally occurring carotenoids are completely insoluble in water and they are associated with lipids which they impart their colour for example milk fat, palm oil, tomatoes and carrots.
Algal carotenes can be used as nutritional substance (provitamin A source) or food colourant in several applications. However, specific regulations on the ingredients used in the respective countries and for the intended use have to be considered.
