Orange Color Extraction from Giant Coreopsis & Barberry Plant
Both Giant Coreopsis (Coreopsis gigantea) and Barberry (Berberis spp.) contain natural pigments that can be extracted for orange color.
Collection & Preparation
- Giant Coreopsis: The flowers and petals are collected when fully bloomed.
- Barberry: The roots, bark, and berries contain alkaloid pigments like berberine, which contribute to yellow-orange hues.
Extraction Methods
- Water Extraction (For Mild & Natural Coloring)
- Alcohol Extraction (For Stronger Pigment & Stability)
- Oil Extraction (For Oil-Soluble Pigments)
Purification & Stabilization
- pH Adjustments: Acidic conditions (pH 4–5) stabilize the color.
- Preservation: Antioxidants like ascorbic acid can enhance shelf life.
Applications of Yellow Pigment
- Food Industry: Natural orange coloring for beverages, confectionery, and sauces.
- Cosmetics: Used in lip balms, creams, and natural dyes.
- Textiles: Traditional dyeing of fabrics (silk, cotton, wool).
