Yellow color extraction from turmeric roots involves isolating curcuminoids, primarily curcumin, which give turmeric its characteristic bright yellow color and potent antioxidant properties. The process begins with cleaning, drying, and grinding the turmeric rhizomes into a fine powder to increase extraction efficiency. Extraction is typically performed using food-grade solvents such as ethanol, methanol, or a mixture of ethanol and water, often under controlled temperature to preserve pigment stability and bioactivity. Advanced techniques like ultrasound-assisted or microwave-assisted extraction are employed to enhance pigment yield and reduce processing time. After extraction, the solution is filtered and concentrated to obtain a vibrant yellow extract widely used in food coloring, cosmetics, pharmaceuticals, and natural dyes. Careful control of extraction parameters like temperature, solvent concentration, and pH ensures high-quality pigment retention and color intensity.
