Yellow Color Extraction from Osage Orange (Maclura pomifera) Inner Bark or Shavings
Osage Orange, also known as Maclura pomifera, is a well-known natural source of yellow to golden-orange dyes. The inner bark and wood contain flavonoids such as morin and maclurin, which produce strong yellow hues.
Collection & Preparation
- Harvesting: The inner bark or wood shavings are collected from mature Osage Orange trees.
- Cleaning: Bark is stripped and washed to remove dirt.
- Drying: The bark and shavings are dried in shade to preserve pigment content.
- Chopping/Shredding: The dried material is chopped into small pieces or ground into a coarse powder for efficient extraction.
Extraction Methods
- Water-Based Extraction (For Dyeing & Pigments)
- Alcohol Extraction (For High-Purity Pigments)
- Fermentation Extraction (Enhances Color Strength)
Filtration & Purification
- The extracted pigment is purified through centrifugation or fine filtration.
- Mordants like alum, tin, or iron can be used to modify the shade.
Applications of Yellow Pigment
- Textile Dyeing: Used for cotton, silk, and wool to achieve bright yellow to golden-orange shades.
- Natural Inks & Paints: Provides strong yellow pigments.
- Cosmetic & Food Applications: Potential use in organic colorants, subject to safety approvals.
