Wood Pressed Oil vs Refined Oil — The Complete Comparison (2026)

By Bhurasa Team··8 min read

The shelves of every Indian supermarket are lined with bottles labelled “groundnut oil”. Some say “cold pressed”. A few say “wood pressed”. Most are simply refined. The difference between them is not a matter of marketing — it is a fundamental difference in chemistry, nutrition, and what ends up in your food.

What is Wood Pressed Groundnut Oil?

Wood pressed groundnut oil — known across India as kachi ghani tel (raw pressed oil) — is extracted using a centuries-old technique involving a traditional wooden churner (ghani) that rotates at low speed and low temperature.

The defining characteristic is temperature: the pressing process stays below 35°C throughout. Because no external heat is applied, the oil retains all its natural fatty acids, antioxidants, Vitamin E, and the distinct nutty aroma of the source groundnut.

The process is slow and yields less oil per kilogram of groundnut compared to industrial methods. That is exactly the point: every molecule of nutrition that industrial processing strips away, cold pressing preserves.

At Bhurasa, we source Kathiyawadi groundnuts from Agro Zone VI, Jamnagar — a narrow belt of alkaline red soil with pH 7.6–9.0, found nowhere else in India. The G20 varieties grown here contain 79–81% oleic acid — among the highest concentrations in the world.

What is Refined Oil? How is it Made?

“Refined” sounds like purity. In reality, refining is an industrial sequence designed to strip the oil of every natural characteristic — colour, smell, flavour, and often nutrition — to create a neutral, shelf-stable commodity.

Here is what standard refined groundnut oil goes through:

  1. High-heat pressing (90–300°C) — destroys heat-sensitive nutrients immediately
  2. Solvent extraction — residual oil extracted using hexane, an industrial petroleum-derived solvent
  3. Degumming — phosphoric acid removes phospholipids and gums
  4. Neutralization — caustic soda (sodium hydroxide) neutralizes free fatty acids
  5. Bleaching — activated clay removes colour and with it, natural antioxidants and carotenoids
  6. Deodorizing — steam distillation at 240–270°C removes the natural aroma
  7. Preservatives added — BHA, BHT, or TBHQ extend shelf life to 12–24 months

The result is a colourless, odourless product that is nutritionally hollow — but cheap, consistent, and indefinitely shelf-stable.

Health Benefits of Wood Pressed Oil

1. High Oleic Acid Content

Oleic acid is a monounsaturated fatty acid (MUFA) associated with cardiovascular health, reduced LDL cholesterol, and anti-inflammatory properties. Bhurasa contains 79–81% oleic acid — significantly higher than industrial groundnut oils (45–55%) because the G20 variety from Zone VI, Jamnagar is specifically cultivated in alkaline-red soil conditions that concentrate oils in the seed.

2. Natural Vitamin E (Tocopherols)

Wood pressed oil retains naturally occurring tocopherols — the Vitamin E family. These are powerful antioxidants. High-temperature refining destroys tocopherols. Some manufacturers synthetically re-add Vitamin E after refining — but synthetic tocopherols have lower bioavailability than the naturally occurring form.

3. Zero Industrial Chemicals

Refined oils carry trace residues of the solvents and chemicals used in processing. Bhurasa contains zero chemicals, zero solvents, zero preservatives. What is in the tin is exactly what came out of the wooden ghani.

4. Preserved Antioxidants and Polyphenols

The carotenoids, polyphenols, and natural antioxidants in groundnut oil are heat-sensitive. Cold pressing preserves them. High-heat refining and the bleaching step destroy them entirely.

How to Identify Real Wood Pressed Groundnut Oil

The market contains many products labelled “cold pressed” or “wood pressed” that are not. Here is how to verify:

1. Check for Sediment

Turn the bottle upside down gently. Authentic unrefined oil will have visible sediment — fine particles of natural groundnut residue. Refined oil appears perfectly clear because all sediment has been chemically removed.

2. Smell It

Open the container and smell before heating. Real wood pressed groundnut oil smells distinctly like roasted groundnuts — rich, warm, unmistakable. If the oil is odourless, it has been deodorized.

3. Check the Colour

Authentic wood pressed oil is deep golden-amber — not pale yellow or clear. Pale colour means bleaching and chemical refining.

4. Verify the Pressing Temperature

Ask the producer or check the label for pressing temperature. Genuine cold-pressed oil is pressed at below 35°C.

5. Check the Shelf Life

Real cold-pressed oil without preservatives has a shelf life of 9 months. A "natural" oil claiming 12–24 months almost certainly contains preservatives.

The Bottom Line

The difference between wood pressed and refined cooking oil is not subtle — it is fundamental. One is a living food product that retains its nutritional character. The other is an industrial commodity that has been chemically stripped to a neutral, stable, shelf-friendly product.

If you cook with oil every day, the cumulative difference in what you are consuming matters. Bhurasa is single-origin wood-pressed groundnut oil from the alkaline red soil of Agro Zone VI, Jamnagar, Gujarat — cold-pressed below 35°C, zero chemicals, zero preservatives.
