# 3. Extracting Moringa Oil: The Cold-Press Method

Cold-pressing is the most natural and chemical-free way to extract Moringa oil (ben oil). It preserves the oil’s nutrients, making it highly valuable for cosmetics, health products, and high-end culinary use. The process involves mechanically pressing the seeds to release the oil without applying heat or chemicals.

Here’s how it works:


# 1. Seed Preparation

Before pressing, the Moringa seeds must be prepared:

# A. Harvesting and Drying

  • If the seeds are collected fresh, they must be dried first to remove moisture and prevent mold.
  • Drying is done in the shade (not under direct sunlight) to preserve oil quality.
  • Seeds should reach a moisture content of about 5–7% before pressing.

# B. Husking (Dehulling)

  • Moringa seeds have a thin, papery outer husk.
  • The oil is inside the inner kernel, so the husk needs to be removed before pressing.
  • Husking can be done by hand, but for bulk production, a simple manual or mechanical dehuller can speed things up.

# 2. Cold-Press Extraction

The pressing itself can be done in a few ways:

# A. Traditional Hand-Pressing (Primitive Method)

If you don’t have a machine, you can still extract oil manually, but it's labor-intensive and inefficient.

# DIY Manual Pressing Methods

  1. Mortar & Pestle / Stone Grinding

    • Crush the seeds into a paste using a mortar and pestle or a grinding stone.
    • Wrap the crushed paste in a cloth and press it hard (e.g., with a stone or wooden board).
    • Some oil will seep out, but yield is very low (~5–10%).
  2. Manual Screw Press

    • A homemade wooden screw press can work.
    • Place crushed seeds inside a strong fabric bag or cylinder, then use a long screw or lever to apply force.
    • The oil drips down as pressure increases.
  3. Boiling and Floating Method (Not Cold-Pressed)

    • In some traditional methods, crushed seeds are boiled in water.
    • The oil floats to the top and is skimmed off.
    • This is NOT a high-grade method and doesn’t count as cold-pressed.

Problem: Manual methods are inefficient. They leave a lot of oil behind. To get good yields, you need a proper oil press.


# B. Using a Small Cold-Press Machine

A proper cold-press machine is the best way to extract Moringa oil efficiently.

# How a Cold-Press Machine Works

  • The dehulled Moringa seeds go into a mechanical screw press.
  • A rotating screw crushes the seeds, applying high pressure.
  • The oil gets squeezed out through a fine mesh or holes in the press.
  • The remaining seed cake (dry, compressed residue) comes out the other end.

This process does NOT use heat (hence "cold-pressed"), ensuring the oil retains its nutrients.

# Types of Cold-Press Machines

  1. Manual Screw Press

    • Hand-cranked, low volume.
    • Can press 1–5 liters of oil per hour.
    • Suitable for small-scale home or rural production.
    • Requires a lot of physical effort.
  2. Small Electric Oil Press

    • A small motorized screw press.
    • Processes 10–30 liters per hour.
    • Costs $500–$3,000 (R10,000–R60,000) depending on size.
  3. Industrial Cold-Press Machine

    • Large-scale, continuous operation.
    • Can press hundreds of liters per day.
    • Used in factories or big commercial operations.

# 3. Filtration & Purification

Freshly pressed Moringa oil contains small seed particles and some impurities. To make high-grade oil, you must filter and settle it.

# A. Natural Settling

  • Let the oil sit in a glass or stainless-steel container for a few days.
  • Heavy particles will settle at the bottom.
  • Pour off the clear oil.

# B. Filtration

For higher clarity:

  • Pass the oil through a fine cloth, coffee filter, or mesh sieve.
  • For commercial-grade oil, use a fine micron filter press to remove micro-particles.

# C. Optional Refining (Not Always Needed)

  • Some cosmetic and food companies refine Moringa oil to remove odor or cloudiness.
  • This involves bleaching or deodorizing, but it reduces nutrients.
  • Cold-pressed oil is usually NOT refined—natural color and scent are desirable.

# 4. Storing & Selling

Once filtered, the pure Moringa oil is ready for use.

# Best Storage Practices

  • Use dark glass bottles or stainless-steel containers to prevent oxidation.
  • Store in a cool, dark place (heat and light degrade oil).
  • Properly stored Moringa oil has a shelf life of 2–5 years (very stable!).

# Selling Cold-Pressed Moringa Oil

  • Wholesale: Bulk buyers (cosmetic, pharmaceutical, supplement companies) often buy in drums (20L, 50L, 200L).
  • Retail: Sold in small 100ml, 250ml, or 500ml bottles for higher profits.

# DIY Setup: Can You Build a Cold-Press?

Yes! If buying a machine is too expensive, you can build a simple mechanical press.

# DIY Moringa Oil Press

Materials Needed:

  1. Metal Cylinder (Stainless Steel)
    • Acts as the press chamber.
  2. Heavy Screw & Handle
    • To apply pressure and squeeze oil out.
  3. Press Plate (Metal or Wood)
    • Moves down inside the chamber to compress seeds.
  4. Oil Drainage Holes
    • Let oil escape while keeping solid seed cake inside.

How It Works:

  • Place seeds inside the cylinder.
  • Turn the screw to apply pressure (like a giant nutcracker).
  • Oil flows out the bottom holes.

A simple DIY press costs a few hundred Rands to build and is much better than hand-crushing.


# Conclusion: Should You Extract the Oil?

Yes! Extracting oil is far more valuable than selling raw seeds.

  • A ton of Moringa seeds (1,000 kg) yields about 250 kg of cold-pressed oil.
  • If oil sells for R500–R1,000 per kg, this means a potential revenue of R125,000–R250,000 per ton of seeds—much higher than selling seeds at R60,000 per ton.
  • Even after accounting for processing costs (R30–R100 per liter), margins are excellent.

A small cold-press setup (DIY or machine) can start producing high-value oil immediately.

  • If you have seeds, it’s better to extract the oil and sell at a premium.
  • Cosmetic, pharmaceutical, and health companies prefer oil, not seeds.

🚀 Recommendation: If investing, get a proper oil press (even a small electric one) rather than selling seeds alone. Build connections with premium buyers who need high-quality oil. Refine your process for top-grade, cold-pressed oil to get maximum profits.
