Abstract
The invention relates to a method for obtaining food colouring derived from saffron, which is based on: the use of saffron threads that are ground and mixed with a base of corn flour, wheat flour, maltodextrin or similar, in a process in which, during mixing, an alcoholic liquid is added to promote the transfer of the colour; and subsequent drying with warm air to produce a product with units of saffron colour and aroma that vary according to the proportions of saffron and base used.

- spraying an alcohol-based liquid into the atomizer while the quantities of the ground saffron and the base are being mixed;
- extracting the mixture from the atomizer;
- drying the mixture by:
