What Is Cold-Pressed Oil? Why Traditional Wood-Pressed Beats Refined Every Time

Discover the real difference between cold-pressed and refined cooking oils. Learn why traditional wood-pressed oils are better for your health — and shop certified, farm-direct oils at Nutraley

You probably have a bottle of cooking oil in your kitchen right now. But do you know how it was made?

Most supermarket oils go through a refining process that involves high heat, chemical solvents, and deodorization. By the time the oil reaches your bottle, much of its natural nutrition has been stripped away. Cold-pressed oil takes a completely different approach — and the difference matters more than most people realize.

At Nutraley, every oil we sell is extracted using traditional wood-press (Chekku) methods — the same technique Indian households have trusted for centuries. In this guide, we break down exactly what cold-pressed means, why it's superior, and how to choose the right oil for your kitchen.

What Does 'Cold-Pressed' Actually Mean?

Cold-pressed oil is extracted by mechanically pressing seeds or nuts at low temperatures — typically below 120°F (49°C). No external heat is applied, and no chemical solvents are used. The result is an oil that retains its natural color, aroma, flavor, and nutritional profile.

Compare this to refined oil, which is extracted using high-heat processing and chemical solvents like hexane, then bleached and deodorized. While this produces a neutral-tasting, shelf-stable oil at lower cost, the process destroys much of the natural goodness.

The Wood-Press (Chekku) Method: How Nutraley Does It

The traditional Indian method for extracting oil is called Chekku or Ghani pressing. A wooden pestle rotates slowly inside a wooden drum, pressing seeds at a natural pace that generates minimal heat. This is the exact method our farm partners use for every batch of Nutraley oil.

Why wood specifically? Wood is a natural insulator that absorbs heat during pressing, keeping temperatures lower than metal presses. It also contributes trace compounds that are believed to enhance the oil's stability and flavor.

Cold-Pressed vs. Refined: A Nutritional Comparison

Here is how cold-pressed and refined oils compare across key nutritional markers:

Property	Cold-Pressed Oil	Refined Oil
Processing Temperature	Below 120°F	Above 400°F
Chemical Solvents	None	Hexane used
Vitamin E Retained	High	Largely destroyed
Natural Antioxidants	Intact	Removed in refining
Omega Fatty Acids	Preserved	Degraded by heat
Natural Aroma & Flavor	Full	Removed / neutral

How to Spot Fake 'Cold-Pressed' Labels

Unfortunately, 'cold-pressed' has become a marketing buzzword that isn't always backed by genuine practice. Here's how to identify genuinely cold-pressed oil:

•       Check for certifications: Look for USDA Organic, FSSAI, or third-party verification. Nutraley carries all three.

•       Check the color: Cold-pressed oils have a natural color — golden sesame, pale yellow groundnut, white coconut. Clear and colorless usually means refined.

•       Check the smell: Real cold-pressed oils have a distinctive, natural aroma. No smell = refined.

•       Check the price: Genuine cold-pressed oil costs more to produce. If the price seems too good, it probably isn't authentic.
