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 miscellas 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. |
