ABSTRACT:
The present invention relates to an efficient method for the extraction of high stability, superior quality, value added, standardized, ready-to-use saffron pigments and flavor concentrate, the process comprising steps of mixing saffron with one food-grade solvent or a combination of more than one food graded-solvents, macerating and agitating the mixture with continuance protection from light condition, centrifuging the macerated mixture to remove undesirable fibrous plant material, cooling the centrifuge immediately, lyophilizing the cooled centrifuge under reduced pressure to obtain crude material, isolating the concentrate by column chromatography, and obtaining brilliant orange color shining saffron pigments and flavor concentrate with recovery of about 95%, and use of the saffron pigments and flavor concentrate of range between 0.05 to 3% in food, pharmaceutical, and allied industries for flavor, and color.
