Cold-pressed oil does something radical: it presses the seed, and stops. What comes out is oil in its most complete, natural form — exactly as nature packed it into that seed. Let us break down why that matters.

What is Refined Oil, Really?

When oil companies extract oil from seeds at industrial scale, they use a multi-step process called RBD — Refining, Bleaching, and Deodorising. Each step strips the oil further.

Seeds are first crushed under high heat (often above 150–200°C) and mixed with a chemical solvent called hexane — the same compound found in petrol — to extract every last drop. The hexane is distilled off afterwards, but trace amounts can remain. The oil then goes through:

• Degumming — treated with phosphoric acid to remove gum-like compounds
• Neutralisation — caustic soda (sodium hydroxide) added to strip free fatty acids
• Bleaching — activated clay and chemicals remove natural colour — including carotenoids, which are natural antioxidants
• Deodorising — steamed above 200°C under vacuum to erase all smell — along with any remaining vitamins and phenolic compounds

The result is an oil that is clear, odourless, tasteless, and long-lasting. It is also, nutritionally speaking, fairly hollow.

What is Cold-Pressed Oil?

Cold-pressed oil is extracted by mechanically pressing seeds at temperatures below 49°C — no external heat, no chemical solvents, no bleaching, no deodorising. The press does the work; nature keeps the nutrition.

In India, this method has a name most people recognise from their grandparents: Kachi Ghani, or the wooden kolhu. Seeds go in whole. The press turns slowly. Oil comes out. Because nothing is removed or added, cold-pressed oil retains:

• Vitamin E (tocopherols) — powerful antioxidants that fight cell damage
• Omega-3 and Omega-6 fatty acids — essential for heart and brain health
• Natural polyphenols and phytosterols — which support cholesterol balance
• Its original colour, aroma, and flavour — which refined oils completely lose
• Zero trans fats — research confirmed cold-pressed oils show no trans fatty acid isomers (Advait Living Research, 2021)

The Comparison — Side by Side

But Wait — What About Smoke Points?

This is the most common concern, and it deserves a straight answer.

Cold-pressed oils generally have a lower smoke point than refined counterparts. Refined oils are specifically processed to raise their smoke point — which is why they are marketed for "high-heat frying". However:

Cold-pressed coconut oil has a smoke point around 175°C, and cold-pressed groundnut oil reaches 160–180°C — both perfectly adequate for everyday Indian cooking, tempering, and sautéing. For repeated high-heat deep-frying, refined oils may be more stable. But at the cost of everything else.

The Health Bottom Line

The link between heavily refined oils and long-term health concerns is well-documented. Research associates regular consumption of refined, trans-fat-containing oils with elevated LDL cholesterol, reduced HDL, increased blood sugar, and heightened cardiovascular risk. The WHO has called for global elimination of industrially produced trans fatty acids. India has set a limit of 2% trans fat in fats and oils — cold-pressed contains 0%.

Cold-pressed oils provide:

• Heart-protective MUFAs and essential fatty acids
• Natural antioxidants that reduce oxidative stress
• Anti-inflammatory compounds that support long-term wellness
• Authentic flavour that reduces the need for artificial seasoning
