Cold Pressed Oil vs Refined Oil: Which Is Better?

Cold Pressed Oil vs Refined Oil: Which Is Better?

Cold pressed oil is better than refined oil for health, flavour, and nutritional value. Cold pressed oil is extracted without heat or chemicals, preserving its natural vitamins, antioxidants, and aroma. Refined oil uses chemical solvents and high-temperature processing that strips away most of these benefits. The trade-off is that refined oil is cheaper and has a longer shelf life.

This article explains exactly what the difference is, why it matters, and how to make the switch without breaking your budget.

How Cold Pressed Oil Is Made

Cold pressed oil is produced by mechanically pressing seeds or nuts at low temperatures — typically below 40°C — with no chemical solvents involved. The traditional method uses a wooden press called a chekku (mara chekku in Tamil), which slowly grinds the seeds and collects the oil that runs out naturally.

The process:

1. Raw seeds or nuts are cleaned
2. Placed into a wooden or mechanical press
3. Pressed slowly at low temperature
4. Oil is collected, filtered naturally, and bottled

No hexane. No deodourising. No bleaching. No hydrogenation.

How Refined Oil Is Made

Refined oil starts with the same seeds but goes through an industrial process designed to maximise yield and shelf life at the cost of nutritional value:

1. Seeds are crushed and mixed with chemical solvents (typically hexane)
2. Heated to high temperatures (160–220°C) to extract maximum oil
3. Degummed, bleached, and deodourised with additional chemicals
4. Hydrogenated in some cases to extend shelf life

The result is a neutral, odourless oil that is consistent and cheap — but largely stripped of the nutrients the seed originally contained.

Nutritional Differences: Why It Matters

Vitamin E: Cold pressed oils retain significant Vitamin E (tocopherols), a fat-soluble antioxidant that protects cells from oxidative damage. Refining destroys up to 80% of Vitamin E content.

Polyphenols and antioxidants: Cold pressed sesame oil retains sesamol and sesamin — powerful antioxidants linked to anti-inflammatory effects. These are almost entirely absent in refined sesame oil.

Essential fatty acids: The natural balance of Omega-3, Omega-6, and Omega-9 fatty acids is better preserved in cold pressed oils. High-heat refining can cause these to degrade or oxidise.

Natural phytosterols: These plant compounds help lower LDL cholesterol. Cold pressed oils retain them; refined oils largely do not.

What About Smoke Point?

This is the most common reason people hesitate to switch to cold pressed oil. Refined oils have a higher smoke point because the compounds that burn at lower temperatures (antioxidants, fatty acids, flavour molecules) have been removed.

Cold pressed oil smoke points:

• Cold pressed groundnut oil: ~160°C — suitable for most Indian cooking, stir-frying, and light frying
• Cold pressed coconut oil: ~177°C — suitable for sautéing and baking
• Cold pressed sesame oil: ~177°C — suitable for cooking; also used as a finishing oil

For deep frying at very high temperatures, you can blend a small amount of cold pressed oil with a neutral oil, or simply reduce the frying temperature slightly. Most everyday Indian cooking — tempering, sautéing, curry bases — is done well below 160°C, making cold pressed oil perfectly practical.

Is Cold Pressed Oil Worth the Higher Price?

Cold pressed oil typically costs 20–40% more than refined oil. Here is why that is worth it for most households:

• You use less oil because the flavour is more intense — a smaller amount goes further
• You eliminate the ongoing cost of chemical residues in your food
• You get the nutritional value you are paying for — oil that actually contains Vitamin E and antioxidants
• For non-cooking uses (hair, skin, Ayurvedic wellness), cold pressed oil is significantly more effective

How to Make the Switch

Switching from refined to cold pressed oil does not have to be all-or-nothing. Here is a practical approach:

1. Start with one oil — replace your everyday cooking oil first. If you cook Indian food, start with chekku groundnut oil.
2. Adjust your heat — turn your flame down slightly when cooking. Cold pressed oils do not need to be heated as high as refined oils to cook food properly.
3. Embrace the aroma — the rich smell of cold pressed oil is a sign of quality, not a flaw. It will make your curries and rice dishes more flavourful.
4. Store correctly — keep cold pressed oil away from direct sunlight and heat to preserve its shelf life. A dark cupboard is ideal.

Frequently Asked Questions

Is cold pressed oil safe for frying? Yes, for most everyday frying and sautéing. Cold pressed groundnut oil and coconut oil handle moderate frying temperatures well. For very high-temperature deep frying, keep the oil below its smoke point.

Does cold pressed oil go rancid faster? It has a shorter shelf life than refined oil — typically 6–12 months — because it retains the natural compounds that eventually oxidise. Buy in a size you will use within that period. Sathva offers 500ml, 1 litre, and 5 litre options to suit different household sizes.

Can I use cold pressed oil for hair and skin as well as cooking? Yes — this is one of the biggest advantages of cold pressed oil. Sathva's sesame oil, coconut oil, castor oil, and almond oil are all used for both cooking and personal care.
