GreenPro Africa’s expertise in oil extraction technology spans both essential oils from aromatic plants and edible oils like soybean and sunflower, combining modern technology with sustainable practices to maximize yield, quality, and farmer value.
Essential Oil Extraction
Essential oils are derived from aromatic and medicinal plants, and GreenPro Africa applies advanced extraction techniques to preserve purity and bioactivity:
- Steam Distillation – the most common method, using steam to release volatile compounds.
- Solvent Extraction – applied for delicate flowers where heat may degrade compounds.
- Cold Pressing – used for citrus oils, preserving natural aroma and nutrients.
- Supercritical CO₂ Extraction – a modern, eco‑friendly method that yields high‑quality oils without solvent residues.
These methods ensure oils retain their therapeutic properties, making them valuable for cosmetics, food, and wellness industries.
Soybean Oil Extraction
Soybean oil is one of the most widely consumed edible oils globally. GreenPro Africa emphasizes efficiency and scalability:
- Preparation Steps – cleaning, cracking, dehulling, and flaking to increase surface area.
- Mechanical Pressing – suitable for small plants; simple but leaves residual oil.
- Solvent Extraction – preferred for large‑scale operations; uses hexane to dissolve oil, achieving >98% recovery.
- Refining – degumming, neutralization, bleaching, and deodorization to improve taste, stability, and shelf life.
This dual approach (pressing + solvent extraction) balances cost efficiency with maximum yield.
Sunflower Oil Extraction
Sunflower oil is prized for its mild flavor and high nutritional value. GreenPro Africa’s process includes:
- Seed Cleaning & Dehulling – removing impurities and hulls to improve oil quality.
- Pressing – mechanical screw presses extract crude oil.
- Solvent Extraction – recovers residual oil from pressed cake, maximizing efficiency.
- Refining – degumming, neutralization, decolorization, and deodorization to ensure clarity and flavour.
- Dewaxing – a unique step for sunflower oil, removing natural waxes to prevent cloudiness at low temperatures.
This integrated system ensures high recovery rates and premium food‑grade oil
