Wood Pressed Oil vs Refined Oil: The Truth About What You're Cooking With

By Thinai Organics • Thinai Wellness

Why Indian kitchens are switching back from refined oil to wood pressed chekku oil, and which wood pressed oil to use for each kind of cooking.

Wood pressed oil is extracted in a traditional wooden mill (chekku or ghani) at low temperature, keeping natural vitamins, antioxidants and flavour. Refined oil uses chemical solvents and high heat, which strip out most of them. For everyday Indian cooking, wood pressed sesame, groundnut and coconut oils are the more traditional choice.

Why the Oil in Your Kitchen Matters

Most Indian households grew up with oil from the local chekku. Then came "light" and "refined" oils, marketed as modern. Decades later, many families are going back to the old way.

What Is Wood Pressed Oil?

Wood pressed oil, also called marachekku ennai or kachi ghani oil, is pressed from seeds in a slowly rotating wooden mill. Very little heat is generated, so the oil comes out without any chemical treatment.

  • Mechanically extracted, with no solvents
  • Low temperature keeps heat-sensitive nutrients
  • Natural colour, aroma and flavour
  • Shelf life of 3–6 months

What Happens During Refining?

  1. Extraction with hexane, a chemical solvent
  2. Degumming
  3. Neutralisation with caustic soda
  4. Bleaching
  5. Deodorisation at 200–250°C

Each step removes something, including much of the natural vitamin E and antioxidants.

Why Families Are Switching to Wood Pressed Oil

1. Natural fats left as they are

Sesame and groundnut oils are rich in monounsaturated and polyunsaturated fats. Wood pressing leaves them unaltered, while high-heat refining and hydrogenation can create oxidised fats and trans fats.

2. More natural antioxidants

Sesame oil naturally contains sesamol and sesamin, antioxidants that are better retained in unrefined oil.

3. Fat-soluble vitamins

Vitamins A, D, E and K need dietary fat to be absorbed, and unrefined oil keeps more of its own vitamin E.

4. No chemical solvents

Wood pressing uses no hexane at all. For families focused on clean eating, this alone is reason enough to switch.

Which Wood Pressed Oil for Which Dish?

How to Switch

  1. Replace one oil at a time, starting with your tempering oil.
  2. Store wood pressed oils away from heat and light.
  3. Expect to use a little less, because the flavour is fuller.

Frequently Asked Questions

Is cold pressed oil the same as wood pressed oil?

The terms are often used interchangeably in India. Strictly, wood pressed means a traditional wooden chekku, while cold pressed can also mean a steel expeller run without added heat.

Can I use wood pressed oil for frying?

Yes. Groundnut and coconut oil handle frying well. Don't let any oil smoke, and avoid re-using frying oil.

Why does wood pressed oil cost more?

A wooden press gets less oil out of each kilogram of seed than chemical extraction, and it is slower.
