Oil extraction from seeds is one of the most lucrative value-addition opportunities in agriculture. With the rising demand for cooking oil and natural products in countries like Kenya, entrepreneurs can turn oilseed crops into a highly profitable business.
This guide explains how oil extraction works, the methods involved, and how you can start your own oil processing venture.
What is oil extraction from seeds?
Oil extraction is the process of removing oil from oil-bearing seeds such as:
- Sunflower seeds
- Soybeans
- Groundnuts (peanuts)
- Sesame seeds
- Canola seeds
The extracted oil is used for cooking, cosmetics, and industrial purposes, while the by-product (oil cake) is valuable as animal feed.
Common oilseed crops in Kenya
Farmers and agripreneurs in Kenya commonly work with:
- Sunflower (most popular for cooking oil)
- Groundnuts (peanut oil)
- Sesame (high-value export crop)
- Soybeans (used for both oil and animal feed)
These crops are widely available and suitable for small- and large-scale processing.
Methods of oil extraction
There are two main methods used to extract oil from seeds:
1. Mechanical Pressing (Cold or Hot Press)
This is the most common method for small and medium-scale businesses.
- Seeds are cleaned and dried
- They are crushed using an oil press machine
- Oil is extracted through pressure
Advantages:
- Affordable startup cost
- Easy to operate
- Produces natural, chemical-free oil
2. Solvent Extraction
This method is used in large-scale industries.
- A chemical solvent (like hexane) is used to extract oil
- Produces higher oil yield
Disadvantages:
- Expensive equipment
- Requires technical expertise
- Not ideal for beginners
Steps in oil extraction process
Starting an oil extraction business requires following a structured process:
1. Cleaning the Seeds
Remove dirt, stones, and impurities to ensure quality oil.
2. Drying
Reduce moisture content to improve oil yield.
3. Crushing or Grinding
Break the seeds to make oil extraction easier.
4. Pressing
Use an oil press machine to extract the oil.
5. Filtration
Filter the oil to remove particles and improve clarity.
6. Packaging
Package the oil in clean containers ready for sale.
Equipment needed
To start a small oil extraction business, you will need:
- Oil press machine
- Seed cleaner
- Grinder or crusher
- Filtering equipment
- Storage tanks
- Packaging materials
These machines are available locally in major towns like Nairobi.
Profitability of oil extraction business
Oil extraction is profitable due to high demand for edible oil.
Example:
- 1 kg of sunflower seeds produces about 300–400 ml of oil
- Cost of seeds: KSh 100 per kg
- Selling price of oil: KSh 250–300 per liter
Additional income comes from selling oil cake as animal feed.
Advantages of oil extraction business
