Yellow color extraction from bay leaves and various tree leaves involves isolating natural pigments such as flavonoids, carotenoids, and xanthophylls responsible for their characteristic yellow hues. The process starts with harvesting, cleaning, and drying the leaves, followed by grinding them into fine powder to increase the surface area for effective extraction. Food-grade solvents like ethanol, methanol, or water are commonly used to extract the pigments, often assisted by techniques such as ultrasound or microwave-assisted extraction to enhance yield and preserve color stability. After extraction, the solution is filtered and concentrated to obtain a vibrant yellow extract used in natural dyes, food colorants, cosmetics, and pharmaceutical products. Careful control of extraction parameters including temperature, solvent concentration, and pH ensures maximum pigment retention and color intensity.
