Every Indian household uses cooking oil every single day. But have you ever stopped to think about what is actually inside that bottle of refined oil you buy from the supermarket?
The truth about refined oil will shock you. And once you understand the difference between wood pressed oil vs refined oil, you will never go back to refined oil again.
What is Wood Pressed Oil?
Wood pressed oil — also called chekku oil, cold pressed oil or ghani oil — is made using a traditional wooden press that has been used in India for thousands of years.
In this process:
- Seeds or nuts are placed inside a large wooden press (chekku)
- A wooden pestle rotates slowly at low speed — usually pulled by bullocks or a motor
- The slow rotation creates gentle pressure that squeezes out the natural oil
- No heat is applied — the oil stays below 40°C throughout the process
- No chemicals are used at any stage
- The oil is filtered naturally and packed directly
The result is pure, natural oil that retains all its original nutrients, antioxidants, vitamins and natural flavour exactly as nature intended.
What is Refined Oil?
Refined oil is what you find in most supermarket brands — Sunflower oil, Soybean oil, Rice Bran oil, Canola oil and similar products.
Here is how refined oil is actually made:
Step 1 — Extraction with Chemical Solvents
Seeds are mixed with a chemical solvent called Hexane — a petroleum byproduct — to extract maximum oil. This process extracts more oil than mechanical pressing but leaves chemical residues in the oil.
Step 2 — Degumming
The oil is treated with phosphoric acid to remove gums and phospholipids.
Step 3 — Neutralisation
Sodium hydroxide (caustic soda) is added to remove free fatty acids.
Step 4 — Bleaching
The oil is passed through bleaching clay to remove colour pigments and remaining impurities — along with most natural antioxidants.
Step 5 — Deodorising
The oil is heated to extremely high temperatures — between 180°C and 230°C — with steam to remove smell. This process destroys all remaining vitamins and creates harmful trans fats.
Step 6 — Chemical Additives
Preservatives, anti-foaming agents and artificial antioxidants like BHA and BHT are added to increase shelf life.
What you get at the end of this process is a clear, odourless, tasteless oil that has been stripped of every single natural nutrient — and loaded with chemical residues instead.
Wood Pressed Oil vs Refined Oil — Key Differences
| Feature | Wood Pressed Oil | Refined Oil |
|---|---|---|
| Extraction Method | Wooden press, slow rotation | Chemical solvent Hexane |
| Heat Used | Below 40°C — cold pressed | 180°C to 230°C — destroys nutrients |
| Chemicals Used | Zero | Hexane, caustic soda, phosphoric acid |
| Nutrients | Fully preserved | Mostly destroyed |
| Natural Antioxidants | High | Removed during bleaching |
| Vitamins | Vitamin E, A, D preserved | Destroyed by high heat |
| Taste and Aroma | Rich natural flavour | Tasteless and odourless |
| Colour | Natural colour of seed | Artificially bleached clear |
| Shelf Life | 6 to 12 months natural | 2+ years with preservatives |
| Trans Fats | Zero | Present from high heat processing |
| Price | Higher | Lower |
| Health Impact | Highly beneficial | Harmful with regular use |
Why Refined Oil is Dangerous for Your Health
1. Trans Fats Cause Heart Disease
When refined oil is heated to 180-230°C during deodorisation, natural unsaturated fats transform into trans fats. Trans fats are directly linked to:
- Increased LDL (bad) cholesterol
- Decreased HDL (good) cholesterol
- Inflammation of arteries
- Higher risk of heart attack and stroke
- Type 2 diabetes
The World Health Organisation (WHO) has called for complete elimination of trans fats from global food supply by 2023 because of how dangerous they are.
2. Chemical Residues Remain in the Oil
Even after multiple refining steps, trace amounts of Hexane solvent remain in refined oil. Hexane is a neurotoxin — meaning it is toxic to your nervous system with long term exposure.
3. Omega-6 Imbalance Causes Inflammation
Most refined oils like sunflower and soybean oil are extremely high in Omega-6 fatty acids. When the ratio of Omega-6 to Omega-3 in your diet becomes too high — as it does with regular refined oil consumption — it causes chronic inflammation throughout your body.
Chronic inflammation is the root cause of most modern diseases including:
- Heart disease
- Cancer
- Diabetes
- Arthritis
- Alzheimer’s disease
4. Zero Nutritional Value
After all the processing, bleaching and deodorising — refined oil has virtually zero nutritional value. You are consuming pure empty calories with chemical residues and no health benefit whatsoever.
Health Benefits of Wood Pressed Oil
1. Retains All Natural Nutrients
Because wood pressed oil is extracted at low temperature without chemicals, it retains:
- Natural Vitamin E — powerful antioxidant
- Natural Vitamin A — supports immunity and vision
- Natural polyphenols — fight free radicals
- Natural phytosterols — support heart health
- Natural lecithin — supports brain function
2. Rich in Natural Antioxidants
Wood pressed oils are naturally rich in antioxidants that protect your cells from oxidative damage — the primary cause of ageing and chronic disease.
3. Better Heart Health
Wood pressed oils contain natural plant sterols and healthy fatty acid profiles that actively support cardiovascular health — unlike refined oils that damage it.
4. Supports Healthy Digestion
The natural phospholipids and enzymes preserved in wood pressed oil support healthy digestion and nutrient absorption — something refined oil completely lacks.
5. Zero Chemical Exposure
No Hexane. No caustic soda. No bleaching agents. No artificial preservatives. What you get is pure oil exactly as nature made it.

Common Questions About Wood Pressed Oil
Is wood pressed oil safe for high heat cooking?
Wood pressed oils are safe for normal Indian cooking temperatures. For very high heat deep frying, groundnut oil and mustard oil are the best choices as they have higher smoke points.
Why does wood pressed oil smell stronger than refined oil?
That strong natural aroma is actually a sign of quality — not a defect. Refined oil is deodorised with high heat which removes the natural smell. Wood pressed oil retains its original natural aroma because nothing has been destroyed.
Does wood pressed oil go bad faster?
Wood pressed oil has a shorter shelf life of 6 to 12 months compared to refined oil because it contains no artificial preservatives. Store in a cool dark place and use within the recommended time. This shorter shelf life is actually proof of its purity.
Is wood pressed oil worth the higher price?
Absolutely. When you compare the health benefits of wood pressed oil vs refined oil and consider the long term health costs of consuming chemical-laden refined oils daily, wood pressed oil is not expensive — it is an investment in your health.
How to Identify Pure Wood Pressed Oil
✅ Natural colour — groundnut oil is golden, sesame oil is amber, coconut oil is clear white
✅ Strong natural aroma of the seed it came from
✅ Slightly cloudy or with natural sediment at bottom
✅ Shorter shelf life — 6 to 12 months
✅ Separates naturally when stored in cold temperature
✅ Labelled as cold pressed, chekku pressed or wood pressed
❌ Avoid oils that are completely clear and colourless
❌ Avoid oils with no smell whatsoever
❌ Avoid oils with shelf life of 2+ years without preservatives mentioned
❌ Avoid suspiciously cheap prices — pure wood pressed oil costs more to make
