The Origins of Cooking Oil
Believe it or not, cooking oil has been around for thousands of years—long before fancy oil presses and modern extraction methods. Ancient humans were resourceful when it came to making use of natural fats and oils. The earliest evidence of cooking oil dates back to ancient civilizations that relied on whatever nature had to offer.
One of the first oils ever produced was olive oil, which traces its roots to around 6000 BCE in the Mediterranean region. Ancient people would crush olives using stones to extract the precious golden liquid. It wasn’t just for cooking, though—olive oil was also used for lamps, cosmetics, and even rituals. Talk about multipurpose!
But olives weren’t the only source of cooking oil. In ancient Egypt, sesame seeds were ground and pressed to make sesame oil, while ancient China developed methods to extract soybean and peanut oils. The techniques were primitive—think manual grinding and crude pressing—but they got the job done.
Some civilizations even used animal fats, like lard and tallow, for cooking before plant-based oils became mainstream. These fats were typically rendered from animal tissues and used as both a cooking medium and a source of energy.
Ancient Oil Sources and Methods
Civilization | Primary Oil Source | Extraction Method | Uses |
Ancient Greece | Olive | Stone crushing and pressing | Cooking, lighting, rituals, cosmetics |
Ancient Egypt | Sesame | Manual grinding and pressing | Culinary use, medicinal purposes |
China | Soybean, Peanut | Boiling and manual pressing | Cooking, medicinal applications |
Native America | Animal fats (lard) | Rendering animal tissues | Cooking, preservation |
Cooking Oils in Ancient Civilizations
Cooking oils were more than just kitchen essentials in ancient times—they were deeply woven into cultural and religious practices. Let’s take a quick tour of how different civilizations utilized cooking oils throughout history.
Ancient Egypt: The Birthplace of Sesame Oil
Ancient Egyptians had a knack for innovation, and their love for oils was no exception. Sesame oil was particularly valued, often used not just for cooking but also for medicinal and cosmetic purposes. They would grind sesame seeds into a paste and then press them to release the oil.
Greece and Rome: Masters of Olive Oil
When you think of olive oil, your mind might go straight to Italy. But it was the ancient Greeks who first made olive oil a culinary superstar. They extracted it by crushing olives with heavy stones, then collecting the oil as it seeped out. The Romans took it a step further, developing more sophisticated presses to boost production. It wasn’t just for cooking—olive oil was a symbol of wealth and was often used in religious ceremonies and personal care products.
Asia: Diverse Oils from Sesame to Coconut
In ancient China and India, oils from sesame, coconut, and soybeans were common. Asian civilizations used simple pressing techniques to extract oil from seeds and nuts. Unlike the West, where animal fats dominated, Asia leaned more toward plant-based oils, partly because of religious beliefs and dietary preferences.
The Americas: Animal Fats and Native Oils
Long before Europeans arrived, Native Americans were using animal fats like lard and tallow for cooking and preserving food. These fats provided essential calories and were often mixed with dried meat and berries to create pemmican—a staple survival food.
Cooking Oils Used by Different Civilizations
Civilization | Common Oils | Key Uses |
Ancient Egypt | Sesame, Castor | Cooking, cosmetics, medicinal |
Greece and Rome | Olive | Cooking, lighting, religious rituals |
Ancient China | Soybean, Peanut | Cooking, medicinal, skincare |
Native Americans | Lard, Tallow | Cooking, preservation, survival food |

Evolution of Cooking Oil Extraction Techniques
As civilizations advanced, so did their methods of extracting cooking oils. The crude stone-crushing methods of ancient times slowly gave way to more efficient techniques, transforming the oil industry.
From Manual Pressing to Mechanical Extraction
The first major leap came with the invention of mechanical presses. Around the 1st century CE, the Romans developed a lever press that significantly increased oil yield compared to traditional stone crushing. This invention made olive oil production faster and more efficient, allowing it to become a staple in both culinary and non-culinary applications.
Fast forward to the 18th and 19th centuries, and we see the emergence of hydraulic presses. These machines used water pressure to crush seeds and nuts, extracting a higher quantity of oil with less labor. By the 20th century, the oil industry witnessed the birth of industrial expellers, which used a screw mechanism to continuously press seeds and extract oil on a large scale.
Modern Extraction Techniques: A Technological Revolution
Today, most cooking oils are produced using solvent extraction and refining methods. One of the most common solvents, hexane, is used to draw oil from seeds like soybeans and canola. The extracted oil then goes through refining, bleaching, and deodorizing (RBD) to remove impurities and enhance flavor.
Another technique that’s gained popularity is cold pressing, especially for oils like extra virgin olive oil and coconut oil. This method preserves more nutrients by avoiding high temperatures, resulting in healthier and more flavorful oils.
Evolution of Oil Extraction Techniques
Era | Technique | Characteristics |
Ancient Times | Stone Crushing | Manual, labor-intensive, low yield |
Roman Era | Lever Press | Increased efficiency, more consistent output |
Industrial Era | Hydraulic Press | Water pressure, higher yield, less labor |
Modern Times | Industrial Expellers, Cold Pressing | High yield, mechanical efficiency, nutrient preservation |
Modern Cooking Oils and Their Impact
The landscape of cooking oils today is a diverse blend of traditional favorites and modern innovations. Supermarkets are stocked with oils like olive, canola, coconut, avocado, and sunflower—each boasting unique health benefits and culinary uses.
Refined vs. Unrefined Oils
Refined oils undergo processes that remove impurities and neutralize flavor, making them suitable for high-heat cooking. On the other hand, unrefined oils maintain their natural flavors and nutrients but are more suitable for low to medium-heat applications.
