Yellow Color Extraction from Saffron Stamens

Yellow color extraction from saffron stamens involves isolating natural pigments such as crocin and flavonoids, which contribute to the bright yellow hue and antioxidant properties of the stamens. The process begins with harvesting and carefully cleaning the saffron stamens, followed by drying and grinding them into a fine powder to enhance extraction efficiency. Extraction is typically performed using food-grade solvents like ethanol or water under controlled temperature and pH conditions to preserve pigment stability and maximize yield. Advanced techniques such as ultrasound-assisted or microwave-assisted extraction may be employed to improve pigment recovery and reduce processing time. After extraction, the solution is filtered and concentrated to produce a vibrant yellow extract widely used in food coloring, cosmetics, and pharmaceuticals. Maintaining optimal extraction parameters ensures the retention of color intensity and bioactive compounds.
