As awareness about natural nutrition grows, many consumers are moving away from refined oils and choosing minimally processed alternatives such as cold-pressed and wood-pressed oils. While these two terms are often used interchangeably, they are not exactly the same. Understanding the difference helps consumers make better decisions when selecting cooking oils for everyday use.
What Is Cold-Pressed Oil?
Cold-pressed oil is extracted using mechanical pressing without excessive heat. The seeds are crushed using metal presses that operate at controlled temperatures to prevent nutrient damage.
The key goal of cold pressing is to extract oil while maintaining the oil’s natural nutrients, aroma, and flavor.
Key characteristics of cold-pressed oils:
• extracted through mechanical pressing
• minimal heat generation during extraction
• no chemical solvents used
• retains natural flavor and nutrients
Research comparing cold-pressed oils with refined oils shows that cold-pressed oils generally contain higher levels of antioxidants, phenolic compounds, and vitamin E because they are not exposed to aggressive refining processes.
What Is Wood-Pressed Oil?
Wood-pressed oil, traditionally known in India as Lakdi Ghani oil, is extracted using a wooden churner powered by slow mechanical rotation.
This method has been used in Indian households for centuries and is deeply rooted in traditional oil-making practices.
The process involves slowly crushing oilseeds inside a wooden chamber using a wooden pestle.
Key characteristics of wood-pressed oils:
• extracted using a wooden ghani (traditional press)
• operates at very slow speeds, usually around 15–18 RPM
• produces very little heat during extraction
• preserves natural nutrients and aroma
Because the process is slower than modern pressing methods, the oil experiences less friction and lower temperature rise, helping preserve delicate bioactive compounds.
Key Differences Between Cold-Pressed and Wood-Pressed Oils
Both methods avoid chemical solvents and heavy refining. However, the main difference lies in extraction speed and equipment.
Cold-pressed oils are typically extracted using modern steel presses, which operate faster and produce oil more efficiently.
Wood-pressed oils use traditional wooden equipment and slower extraction speeds.
Key differences include:
Cold-Pressed Oil
• extracted using metal mechanical presses
• faster extraction process
• moderate temperature control
• commonly used in modern oil production
Wood-Pressed Oil
• extracted using wooden ghani equipment
• very slow extraction speed (15–18 RPM)
• minimal heat generation
• deeply rooted in traditional Indian practices
Why Extraction Speed Matters
One of the most important factors in oil extraction is temperature.
High friction during fast pressing can increase temperature, which may affect sensitive nutrients present in oil.
Slow pressing methods help preserve important natural compounds such as:
• antioxidants
• phytosterols
• tocopherols (vitamin E)
• natural flavor compounds
Scientific studies on mechanically extracted oils indicate that lower temperature processing helps retain more bioactive compounds compared to oils exposed to high heat during industrial refining.
Why Many Consumers Prefer Wood-Pressed Oils
In recent years, there has been growing interest in traditional oil extraction methods.
Consumers often choose wood-pressed oils because they are associated with:
• traditional food practices
• minimal processing
• natural flavor and aroma
• closer connection to farm-based production
These oils are often valued not only for their nutritional properties but also for their cultural and traditional significance.
Final Thoughts
Both cold-pressed and wood-pressed oils are significantly less processed than refined oils and preserve more of the oil’s natural properties.
However, wood-pressed oils represent a slower and more traditional extraction method, often associated with lower processing temperatures and heritage oil-making practices.
Understanding these differences helps consumers make informed choices and reconnect with traditional approaches to food and nutrition.
