Cooking oil is an essential part of almost every Indian kitchen, whether it is used for preparing everyday sabzi, frying snacks or cooking traditional dishes. While mustard oil, sunflower oil and refined oils have long been popular choices, cold-pressed oils are increasingly attracting attention among people looking for minimally processed food products.

But what exactly is cold-pressed oil? How is it extracted, and does it offer any advantages over conventional cooking oils? With numerous varieties available in the market, understanding the extraction process and reading product labels can help you make a more informed choice.

What Is Cold-Pressed Oil?

Cold-pressed oil is extracted from oilseeds, nuts or other oil-bearing ingredients using mechanical pressure, without deliberately applying high heat during extraction.

Unlike some conventional extraction methods that involve higher temperatures or chemical solvents, cold pressing relies primarily on physical pressure to release the oil. Traditional Indian methods using a ghani or kolhu are examples of mechanical oil extraction.

The process generally involves minimal processing, although filtration and other permitted steps may be used depending on the manufacturer. Cold-pressed oils often retain the characteristic aroma, flavour and colour of their source ingredients.

However, the term does not automatically mean that an oil is healthier in every respect. Its nutritional profile depends largely on the source ingredient, fatty acid composition, processing and storage conditions.

How Is Cold-Pressed Oil Made?

The journey from seeds to the finished bottle involves several important stages.

1. Selecting and Cleaning the Seeds

The process begins with selecting suitable raw materials, such as mustard seeds, sesame seeds, groundnuts or coconuts. The seeds are cleaned to remove dust, stones and other unwanted particles before extraction.

The quality of the raw material can influence the flavour, aroma and overall quality of the final oil.

2. Mechanical Pressing

The cleaned seeds are placed in a mechanical press or traditional ghani. Pressure is applied to release the oil without deliberately using high extraction temperatures.

The amount of oil obtained depends on the type of seed, its moisture content and the extraction equipment.

3. Separation and Filtration

After pressing, the extracted oil may contain small particles of seed material. It can be allowed to settle or passed through suitable filters to remove these suspended solids.

Some cold-pressed oils are sold in a relatively unfiltered form, while others undergo additional filtration for a clearer appearance.

4. Packaging and Storage

The finished oil is packed in suitable containers to protect it from contamination, light and air exposure. Proper packaging and storage are important because oils can deteriorate through oxidation, affecting their flavour and quality.

Which Cold-Pressed Oil Should You Choose for Your Kitchen?

Different oils have different flavours and nutritional characteristics. The best choice depends on what you cook, how you cook it and your overall dietary needs.

• Cold-pressed mustard oil: Has a strong, distinctive flavour and is commonly used in traditional Indian cooking. Check that the product is legally marketed for edible use in your region.

• Cold-pressed groundnut oil: Offers a mild, nutty flavour and can suit several everyday cooking applications. Its suitability for high-heat cooking depends on the specific product and its stability.

• Cold-pressed sesame oil: Has a characteristic nutty aroma and works well in many regional Indian recipes, dressings and finishing applications.

• Cold-pressed coconut oil: Provides a distinct coconut flavour and is used in various traditional dishes. It is relatively high in saturated fat, so portion size matters.

• Cold-pressed sunflower oil: Generally has a mild taste and is rich in unsaturated fats, although its fatty acid profile varies by variety.

No single oil is ideal for every dish. Choosing oils with different unsaturated fatty acid profiles and using them in appropriate quantities can help support a balanced diet.

7 Things to Check Before Buying Cold-Pressed Oil

Before choosing a bottle from the supermarket or an online store, pay attention to these factors.

1. Check the Source Ingredient

Look for clear information about whether the oil is made from mustard, groundnut, sesame, sunflower or another ingredient. Avoid products with unclear descriptions of their composition.

2. Read the Extraction Method

Look for an explicit description of mechanical or cold-press extraction. Terms such as natural, traditional and premium are not, by themselves, proof of a particular manufacturing process.

3. Verify Food Safety Information

Check the manufacturer's details, batch number, manufacturing or packing date, best-before date and applicable food safety licence information. In India, packaged edible oils should comply with the relevant Food Safety and Standards Authority of India requirements.

4. Examine the Ingredients

If you want a single-source oil, check whether the product contains only the oil named on the label. Do not assume that every product marketed as cold-pressed contains only one type of oil.

5. Choose Suitable Packaging

Dark or opaque packaging can help protect oil from light exposure. Once opened, store the bottle tightly closed in a cool, dry place, away from direct sunlight and heat.

6. Consider Your Cooking Temperature

Different oils behave differently when heated. Check the manufacturer's guidance and avoid repeatedly overheating oil or using oil that has become smoky, unusually dark or rancid.

Cold-pressed oil is not automatically suitable for every high-temperature cooking method simply because it is minimally processed.

7. Compare Price With Quality

Cold-pressed oils can cost more because of the extraction method, raw material and production scale. However, a higher price does not automatically guarantee better nutritional quality. Compare the ingredient, product information, freshness, packaging and intended use before making a decision.

Is Cold-Pressed Oil Healthier Than Refined Oil?

Cold-pressed oils may retain more of certain naturally occurring compounds, depending on the source ingredient and processing method. They may also preserve more of the characteristic flavour and aroma of the original seeds.

However, refined oils can offer advantages such as a more neutral flavour, improved clarity and greater suitability for certain high-temperature applications. The health impact of a cooking oil depends significantly on its fatty acid composition, how much is consumed and how it is used.

For cardiovascular health, replacing some saturated fats with unsaturated fats is generally beneficial. Therefore, the distinction between cold-pressed and refined oil should not be the only factor in your decision.

Expert Advice: Make an Informed Choice

Dr. Shilpa Vora, Chief R&D Officer at Marico Limited and a food expert associated with Saffola, has highlighted the growing consumer interest in understanding where food comes from and how it is produced.

This awareness is also influencing the cooking oil market, where traditional extraction methods and less processed ingredients are receiving greater attention.

Nevertheless, consumers should look beyond marketing claims and evaluate the actual product, its composition, quality and suitability for their cooking habits.

The Bottom Line

Cold-pressed oil offers an alternative for people who prefer mechanically extracted oils with their characteristic flavour and aroma. From mustard and groundnut to sesame and coconut, each variety has its own culinary uses and nutritional profile.

Before buying, check the ingredients, extraction method, food safety details, packaging and intended cooking application. Most importantly, remember that no cooking oil should be consumed in unlimited quantities.

A balanced diet, appropriate portion sizes and sensible cooking practices matter more than choosing an oil solely because its label says cold-pressed.
