For decades, the Indian kitchen knew one kind of oil — the kind pressed the old way, in wooden mills called ghanis, slow and cold, preserving everything that made the oil worth using. Then came industrialisation, and with it, refined oils that promised longer shelf life, uniform colour, and higher smoke points. Today, millions of health-conscious households across Tamil Nadu, Bengaluru, Hyderabad, and the rest of South India are asking a simple question: were we right to switch?
The answer, backed by nutrition science and centuries of culinary tradition, is increasingly clear. Wood-pressed oils are not just a nostalgic preference — they are a genuinely superior choice. This article explores why.
What Exactly Is Wood-Pressed Oil?
Wood-pressed oil, also called cold-pressed or kachi ghani oil, is extracted by crushing oilseeds in a traditional wooden or stone press without applying external heat. The seeds whether groundnut, sesame, or coconut are fed into the press and oil is slowly extracted through mechanical pressure alone. The temperature during extraction stays naturally low, typically below 50 degrees Celsius.
Brands like Aurora Gold by GS Oil Manufacturing follow this traditional extraction method rigorously, ensuring that every bottle of Aurora Gold Groundnut Oil, Sesame Oil, and Coconut Oil carries the full nutritional integrity of the seed.
What Is Refined Oil and How Is It Made?
Refined oils go through an industrial multi-stage process that includes:
- Solvent extraction using chemical solvents like hexane to maximise oil yield
- Degumming to remove phospholipids
- Neutralisation with sodium hydroxide (caustic soda) to reduce acidity
- Bleaching using activated clay to remove colour pigments and impurities
- Deodorisation at extremely high temperatures (200-270 degrees Celsius) to eliminate odours
Each step strips the oil of something natural. By the time refined oil reaches your kitchen shelf, it has been chemically treated, bleached, and heat-processed multiple times.
Nutrient Retention: Where Wood-Pressed Oils Win Decisively
The low-temperature extraction in wood pressing preserves nutrients that high-heat industrial refining destroys. Here is what you retain in a genuinely wood-pressed oil:
- Natural antioxidants including vitamin E and polyphenols
- Phytosterols that support healthy cholesterol levels
- Lecithin and phospholipids beneficial for brain and liver health
- Natural omega fatty acids in their original, unaltered form
- Authentic aroma compounds that also contribute functional nutritional value
Refined oils, after deodorisation and bleaching, lose much of this nutritional complexity. What remains is primarily fat calories with minimal accompanying nutrition.
Taste and Aroma: The Difference You Can Sense
Open a bottle of Aurora Gold Wood-Pressed Groundnut Oil and compare it to a standard refined groundnut oil. The difference is immediate. The wood-pressed version carries a rich, warm, nutty aroma that signals the oil is genuine and unprocessed. The refined version, after deodorisation, is nearly odourless and flat.
In Indian cooking, the aroma of the oil is not just about smell — it is a flavour foundation that carries through the entire dish. Traditional recipes from Tamil Nadu, Karnataka, and Andhra Pradesh were designed with these natural oils in mind. Using wood-pressed sesame oil in a Chettinad curry, or wood-pressed coconut oil in a Kerala-style fish fry, reproduces a depth of flavour that refined oils simply cannot deliver.
Chemical Exposure: A Critical Concern
Perhaps the most important reason to choose wood-pressed oil is what is absent from it. Refined oils may carry trace residues of chemical solvents used during extraction, along with by-products of the high-temperature deodorisation process such as trans fats and oxidised compounds.
Aurora Gold’s wood-pressed oils are produced without chemical solvents, without bleaching agents, and without artificial deodorisation. The oil you receive is as close to natural as it can be — the seed’s oil, extracted with nothing more than mechanical pressure and traditional knowledge.
Why Consumers Are Switching Back to Traditional Oils
Across South India’s urban markets — from Bangalore’s HSR Layout to Chennai’s Anna Nagar, from Hyderabad’s Banjara Hills to Coimbatore’s RS Puram — there is a visible return to traditional cooking oils. The reasons are multiple:
- Rising awareness of the industrial refining process and its impacts
- Growing preference for chemical-free, natural food products
- A revival of traditional Indian dietary wisdom
- Increased availability of quality wood-pressed brands like Aurora Gold
- Recommendations from nutritionists and Ayurvedic practitioners
This is not a fringe movement. Major grocery retailers, organic food stores, and direct-to-consumer brands have all noted a consistent uptick in demand for wood-pressed and cold-pressed oils over the past several years.
Cooking Performance: What About Smoke Points?
A common concern raised about wood-pressed oils is smoke point. Refined oils typically have higher smoke points due to the removal of impurities. However, wood-pressed groundnut oil has a perfectly adequate smoke point of around 180-200 degrees Celsius, making it suitable for everyday frying, sauteing, tempering, and deep frying at home temperatures.
For everyday Indian cooking — dal tadka, sabzi, dosas, fish curries, and stir fries — wood-pressed oils perform excellently. Industrial deep frying at extremely high temperatures is a separate context. For home kitchens and restaurants, Aurora Gold’s wood-pressed range is fully capable.
Conclusion
The comparison between wood-pressed and refined oils is not simply about old versus new. It is about natural versus chemically processed, nutrient-rich versus nutrient-stripped, authentic taste versus artificial neutrality. Traditional wood-pressed extraction, as practiced by Aurora Gold, preserves what refining destroys.
For families, fitness enthusiasts, homemakers, and chefs across South India who care about what goes into their food, switching to wood-pressed oil is one of the most meaningful changes you can make in your kitchen.
