Bull-driven Oil Extraction Method
The bull-driven oil extraction method, also known as Ghani oil extraction or Kolhu oil pressing, is a traditional method used in India and other parts of the world for extracting oil from seeds. This process involves a large wooden or stone mortar (Ghani/Kolhu), in which a wooden or iron pestle is rotated using a bull, manually or with minimal mechanical assistance.
How It Works
- Loading Seeds – Oilseeds (such as sesame, coconut, mustard, groundnut, or sunflower) are placed inside the mortar.
- Crushing Process – A wooden pestle is rotated by a bull or an animal-driven mechanism, crushing the seeds and slowly extracting oil.
- Natural Filtration – The oil is naturally filtered and collected without applying external heat or chemicals.
- Residue Utilization – The leftover seed cake is rich in nutrients and used as cattle feed or organic manure.
Benefits of Bull-Driven Oil Extraction
1. Cold-Pressed & Nutrient-Rich
- Since no heat is applied during extraction, the oil retains natural antioxidants, vitamins, and minerals.
- This makes it healthier compared to industrially refined oils.
2. Chemical-Free & Pure
- Unlike commercial refining processes that use solvents and chemicals, this method ensures pure and natural oil.
- No artificial preservatives or additives are required.
3. Environmentally Friendly
- It is a sustainable and eco-friendly process as it consumes minimal energy and does not generate industrial waste.
- Promotes biodiversity by encouraging traditional farming practices.
4. Supports Local Farmers & Rural Economy
- Encourages traditional livelihoods for farmers and bull keepers.
- Helps in preserving ancient agricultural techniques.
5. Better Taste & Aroma
- Cold-pressed oils from this method have a richer aroma, deeper color, and natural flavor compared to refined oils.
Challenges
- Lower yield compared to modern mechanical pressing.
- Time-consuming process as it is slow and labor-intensive.
- Requires maintenance of traditional wooden or stone pressing units.
Why It’s Gaining Popularity Again
With growing awareness about healthier, organic, and sustainable food choices, more people are shifting towards bull-driven and cold-pressed oils. Consumers prefer these oils over chemically refined options due to their health benefits and environmental sustainability.
