PROCESS FOR OBTAINING AN EXTRACT OF SAFFRON

摘要

The process comprises subjecting the stigmas of the saffron flower to the operative phases of dehydration, trituration by grinding, triple stirring and heating with a mixture of de-ionized water/96 DEG alcohol, filtering the resultant micellas and concentration under vacuum and low temperature conditions in order to obtain a liquid extract with solids comprised between 2 and 3 %; from said liquid extract a solid or powdery extract is obtained through dehydration by lyophilisation, sublimation under 0 DEG C, pouring and heating at temperature lower than 38 DEG C and resting. This extract can be used as a substitute for saffron and artificial dyes.
