Cold Pressed vs Kachi Ghani vs Expeller Pressed Oils: Which One to Use

Cooking oil is more than a kitchen ingredient; it is the foundation of good health and authentic flavour. Across India, different regions favour different oils such as mustard in the north, coconut in the south, sesame in the east, and groundnut in the west. Yet the real difference lies not in the type of seed but in the extraction process used to make the oil.

Cold-pressed, Kachi Ghani, and expeller-pressed oils may look similar on the shelf, but how they are made decides their purity, nutrient profile, and taste. Knowing the difference helps you choose the right oil for every kind of cooking.

What Are Cold-Pressed Oils and Why Do They Matter?

Cold-pressed oils are extracted by pressing seeds or nuts at low temperatures without adding any heat or chemicals, unlike refined oils which are extracted using high heats and chemical solvents, and temperatures going as high as 320°C. ,. This process preserves the natural antioxidants, vitamins, and essential fatty acids in the oil. The result is a pure, nutrient-rich oil that retains the true flavor and aroma of the seed. There are different methods of cold-pressing, and there is no official standard or limit to the oil pressing temperature. You can consider cold-pressing like an umbrella term, which includes even oils extracted from expellers etc, at 150°C. This temperature is lower than refined but much higher than the temperature at which the nutrients of the oilseed survive. 

When oils are truly cold-pressed, like India’s traditional Kolhu-pressing method, coconut oil will smell like fresh coconut, while cold-pressed groundnut oil will carry  a deep, nutty aroma that enhances traditional recipes. These oils are also rich in monounsaturated fats and vitamin E, making them beneficial for heart health and skin nourishment.

Understanding KachiGhani Oils

Kachi Ghani or Kolhu-pressing is the traditional Indian method of cold pressing using a wooden churner known as a kolhu. Seeds are slowly crushed to extract oil while maintaining a low temperature under 40°C so that natural nutrients and enzymes stay intact. This age-old method has been used in Indian households for centuries because it produces oil in its purest and most flavourful form.

Kachi Ghani oils are typically unrefined and chemical-free. You may find some seed sediments or a darker color, both signs of authenticity and minimal processing. The slow churning method prevents heat buildup and keeps essential compounds like omega-3 and antioxidants intact.

Mustard oil made through the Kachi Ghani process is one of the most popular examples. Its pungent aroma and rich flavor come from natural compounds that support digestion and improve circulation. The oil also has antibacterial properties, making it ideal for Indian cooking and pickling.

When to use:

 Use Kachi Ghani oils for tadkas, pickles, curries, stir-fries, and other Indian dishes. Their strong aroma and robust flavor enhance traditional recipes and make them a healthier alternative to refined oils.

What Are Expeller-Pressed Oils

Expeller-pressed oils are extracted using mechanical pressure without chemicals, similar to cold pressing, but the friction created during the process can slightly raise the temperature to about 70°C-100°C. The result is oil that is still natural but has a lighter flavor and longer shelf life than cold-pressed or Kachi Ghani oils.

These oils retain a fair amount of nutrients and are more stable for high-heat cooking. They strike a balance between health and practicality, making them suitable for both home and restaurant kitchens.

When to use:
 Expeller-pressed oils are ideal for deep frying, roasting, grilling, or baking. They handle higher temperatures better without breaking down quickly.

Refined vs Natural Oils

Refined oils undergo multiple chemical treatments such as bleaching, neutralizing, and deodorizing to remove impurities and extend shelf life. However, these processes also strip away the natural nutrients, antioxidants, and flavor of the oil. What remains is a clear, odorless oil with minimal health benefits.

Natural oils like cold-pressed and Kachi Ghani retain all their original compounds, providing plant-based nutrients and antioxidants that help reduce inflammation, support heart function, and improve metabolism. The taste difference is noticeable too; natural oils add authentic aroma and texture, while refined oils often feel flat and lifeless.

If your oil looks crystal clear or lacks aroma, it is likely refined. Real oils are nutrient-dense and may appear slightly cloudy or thick, which is a sign of purity.
