What is it used for?

Colouring of food products is required:

• To replace colour lost during preparation (e.g. preserved fruits and vegetables);
• To makeup the colour of a product whose ingredients cause it to become fade (e.g. sauces and drinks);
• To ensure consistent colour of products (e.g. confectioneries and desert products);
• To render the characteristic flavour more recognizable (e.g. synthetic syrups).
• Technical Possibilities for Colouring Food Products:
• Through the addition of colourant foods (e.g. Beetroot).
• With natural colouring agents occurring in food (e.g. Beta - carotene).
• With natural colouring agents not occurring naturally in food (e.g. Caramine).
• With permitted synthetic food colours.
• With inorganic pigments.
