Walk into any Indian supermarket and you will find two types of cooking oil sitting next to each other. One is crystal clear, odourless, and cheap. The other is darker, slightly cloudy, smells like the seed it came from, and costs more. The difference between them is not just price — it is what happened to the oil before it reached the bottle.
Cold pressed oil retains the natural nutrients, antioxidants, and fatty acid structure of the original seed. Refined oil is processed with high heat, chemical solvents, and bleaching agents — a process that extends shelf life but removes most of what made the oil nutritionally useful in the first place.
What Cold Pressed Actually Means
Cold pressing — known as kachi ghani in North India — extracts oil by crushing seeds mechanically at temperatures below 50°C. No external heat is applied. No chemical solvents are used. The oil that comes out retains its natural colour, smell, and nutritional compounds.
The yield is lower than industrial refining — approximately 30–40% less oil per kilogram of seeds. That is why cold pressed oil costs more. It is not a marketing premium. It is the actual cost of not using hexane solvent to extract every last drop.
The result is an oil that looks and smells like the seed it came from — slightly cloudy, distinctly flavoured, and nutritionally intact.
What Refining Actually Does to Oil
Refined oil goes through multiple industrial stages before it reaches your kitchen. Each stage removes something from the oil:
- Solvent extraction (hexane) — chemical solvent dissolves the oil out of seeds, increasing yield significantly. Hexane is then evaporated off, but trace amounts may remain
- Degumming — removes phospholipids and natural gums
- Neutralisation — removes free fatty acids using sodium hydroxide
- Bleaching — removes colour compounds and pigments using activated clay
- Deodorisation — steam distillation at 230–260°C removes smell and taste
The deodorisation stage is the most nutritionally damaging. At 230–260°C, most naturally occurring antioxidants, polyphenols, and vitamin E are destroyed. Research suggests the deodorising stage can produce small amounts of trans fats — a 2024 peer-reviewed study on deodorised sunflower oil (PubMed) confirmed higher trans fatty acid levels in repeatedly deodorised oils compared to cold pressed versions.
What remains is a neutral, stable, long-shelf-life fat — but one that has lost most of what made it nutritionally useful.
The Nutrition Difference — What the Numbers Show
Per 100ml, cold pressed oils typically retain:
- Vitamin E (tocopherols): up to 30–40mg in cold pressed groundnut oil vs under 10mg in refined versions — a loss of 60–70% through processing
- Polyphenols and antioxidants: sesamol in sesame oil, resveratrol in groundnut oil — largely intact in cold pressed, largely destroyed in refined
- Natural fatty acid balance: preserved in cold pressed; MUFA content survives refining reasonably well, but the absence of protective antioxidants means the fat oxidises faster once opened
One important nuance: ICMR dietary guidelines do not categorically condemn refined oils — they recommend limiting total fat intake and diversifying fat sources. The concern with refined oils is not one meal. It is daily use over years, where the cumulative absence of protective antioxidants adds up.
The Smoke Point Question — What Most Posts Get Wrong
This is where most cold pressed oil content misleads people — either by ignoring smoke points entirely or by claiming cold pressed oils can handle any cooking temperature.
Smoke point is the temperature at which an oil begins to break down and produce harmful compounds. Exceed it — with any oil, cold pressed or refined — and you produce aldehydes and free radicals that are genuinely damaging. The oil type matters less than whether you stay below its smoke point.
Here are the realistic smoke points for cold pressed oils commonly used in Indian kitchens:
- Cold pressed mustard oil: 250°C — highest of any traditional Indian oil. Safe for deep frying, high-heat tadka, and roasting
- Cold pressed groundnut oil: 230°C — excellent for frying, stir-frying, and everyday cooking
- Cold pressed sesame oil: 177–210°C depending on grade — good for sautéing and tadka, not ideal for sustained deep frying
- Cold pressed virgin coconut oil: 177°C — best for low-to-medium heat cooking, South Indian curries, and baking. Not recommended for deep frying
Practical rule: match the oil to the cooking method. For high-heat Indian cooking — kadai sabzi, deep-fried snacks, North Indian tadka — cold pressed mustard oil is the most suitable choice. For medium-heat cooking, dressings, and South Indian dishes, cold pressed sesame oil is excellent.
Which Cold Pressed Oil for Which Indian Cooking Purpose
- Deep frying and high-heat tadka: Cold pressed mustard oil (250°C) or cold pressed groundnut oil (230°C)
- Everyday sabzi and dal: Cold pressed mustard oil in North/East India; cold pressed groundnut oil in South/West India
- South Indian cooking and curries: Cold pressed virgin coconut oil or cold pressed sesame oil
- Salad dressings and finishing: Cold pressed sesame oil — use raw, do not heat
- Baking: Cold pressed virgin coconut oil — neutral enough for most recipes
One common myth worth addressing: extra virgin olive oil is often marketed as the healthiest cooking oil for Indians. It has a smoke point of 160°C — well below the 180–220°C range of most Indian deep frying. It is genuinely useful for salads and light sautéing. It is not appropriate for everyday Indian cooking methods.
How to Identify Genuine Cold Pressed Oil Before Buying
The cold pressed category has a growing greenwashing problem in India. "Natural," "pure," and even "kachi ghani" are used loosely on labels without any regulatory requirement to back them up. Here is what to actually check:
- Look for FSSAI licence number — mandatory on all packaged food products in India. Absence of a licence number is a red flag regardless of claims on the label
- Check for certification: As per FSSAI's Organic Food Standards, only products certified under NPOP or PGS-India are permitted to carry the India Organic or Jaivik Bharat mark. If the label says "organic" without one of these marks, it is an unverified claim
- Colour and smell: Genuine cold pressed oils are darker, slightly cloudy, and smell distinctly of the source — mustard oil is pungent, sesame oil is nutty, coconut oil is mildly sweet. Crystal-clear, odourless oil claiming to be cold pressed is a contradiction in terms
- Shelf life: Cold pressed oils have a shorter shelf life than refined because their natural antioxidants, while protective in the body, do not prevent rancidity as effectively as chemical preservatives. 6–12 months is typical. A claimed shelf life of 24+ months on cold pressed oil warrants scrutiny
- Price: Genuine cold pressed oil from a traceable source costs more than refined oil. If it is priced the same as refined oil on a supermarket shelf, ask why
At PureStora, every vendor selling cold pressed oil is verified for FSSAI compliance before listing. You can browse certified cold pressed cooking oils available on the platform.
Frequently Asked Questions
Is cold pressed oil better than refined oil for daily Indian cooking?
For most daily cooking purposes, yes — cold pressed oil retains natural antioxidants and nutrients that refining destroys. The key condition is matching the oil to the cooking temperature. Cold pressed mustard oil (250°C smoke point) and cold pressed groundnut oil (230°C) handle high-heat Indian cooking well. Cold pressed sesame and coconut oils are better suited to medium-heat cooking.
Can I use cold pressed oil for deep frying?
It depends on which cold pressed oil you choose. Cold pressed mustard oil at 250°C and cold pressed groundnut oil at 230°C are both suitable for deep frying at typical Indian temperatures of 180–200°C. Cold pressed coconut oil (177°C) and cold pressed sesame oil are not recommended for sustained deep frying — they will exceed their smoke point and break down.
How do I know if cold pressed oil is genuine?
Check for FSSAI licence number on the packaging — mandatory for all packaged food in India. Genuine cold pressed oil is darker, slightly cloudy, and smells of the source seed. Crystal-clear, odourless oil claiming to be cold pressed is unlikely to be unrefined. For certified organic cold pressed oils, look for the India Organic (NPOP) or Jaivik Bharat mark on the label. You can find verified cold pressed and organic cooking products on PureStora — each vendor is checked for valid certification before listing.
Is cold pressed oil safe for people with heart conditions?
Research suggests cold pressed oils — particularly groundnut, sesame, and mustard — contain natural antioxidants and healthy fatty acid profiles that may support cardiovascular health as part of a balanced diet. However, all oils are calorie-dense, and total fat intake matters regardless of oil type. Always consult your doctor or a registered dietitian if you have a specific heart condition before making significant dietary changes.
Conclusion
The difference between cold pressed and refined oil is not about one being "good" and the other "poison" — it is about what survives the extraction process and whether it matches how you cook. Cold pressed oils retain nutrients and antioxidants that refining removes, and for most Indian cooking temperatures they perform well — provided you choose the right oil for the right method.
