Let's begin.

What Are Cold Pressed Oils?

Cold pressed oils are extracted from seeds or nuts using a mechanical press without applying heat. This method preserves the oil's nutritional value, antioxidants, and flavor. Unlike refined oils, they are free from chemicals, high-heat processes, and artificial additives.

Benefits of cold pressed oils include:

  • Rich in antioxidants
  • Packed with essential fatty acids
  • Retains vitamins like A, E, and D
  • Better for heart, skin, and overall wellness
  • Chemical-free and minimally processed

But the challenge lies in identifying genuine cold pressed oils, especially when many companies label refined or mixed oils as “cold pressed.” So how can you trust what you're buying?

5 Easy Tests to Identify Pure Cold Pressed Oil at Home

You don't need a lab to check oil purity. Just follow these simple home tests to determine whether your oil is truly cold pressed or not.

1. The Freezing Test

How to do it:

  • Pour 2-3 tablespoons of the oil into a small container
  • Seal it and place it in the freezer for 4–6 hours

What to observe:

  • Pure cold pressed oil will become cloudy or semi-solid
  • If the oil remains fully liquid, it may be mixed with refined oil or additives



Why it works:

Natural oils have fatty acids that solidify at low temperatures, while adulterated oils stay liquid due to added chemicals.

2. The Paper Blot Test

How to do it:

  • Put 2–3 drops of the oil on a clean white paper or blotting paper
  • Let it sit for 30 minutes in a cool place

What to observe:

  • A pure oil will leave a light, greasy patch without any dark ring
  • If you see a yellowish halo or rings, the oil might be adulterated

Why it works:

Adulterants leave colored residues or extra moisture, which stain the paper unnaturally.

3. The Smell Test

How to do it:

  • Pour a few drops on your palm or spoon
  • Rub gently and smell it

What to observe:

  • Cold pressed oils have a fresh, nutty, or seed-specific aroma
  • If the oil smells rancid, synthetic, or lacks fragrance, it's likely impure

Why it works:

Heat-extracted or refined oils lose their natural smell during processing.

4. The Taste Test

How to do it:

  • Take a small sip (½ teaspoon)
  • Let it linger on your tongue for a few seconds

What to observe:

  • Genuine cold pressed oil will taste natural, earthy, and slightly bitter or nutty depending on the seed
  • A bland or chemical-like taste indicates refining or dilution

Why it works:

Cold pressed oils retain seed flavor, unlike neutral-tasting refined oils.

5. The Flame Test (For Mustard Oil)

How to do it:

  • Dip a cotton wick in mustard oil
  • Light it like a lamp

What to observe:

  • Pure mustard oil burns with a steady flame and mild smoke
  • If it sputters, smells like kerosene, or gives off black smoke, it is adulterated

Why it works:

Mustard oil with added solvents or paraffin behaves differently under fire.

Note: Perform this test in a safe, well-ventilated space.

Bonus Tip: Always Check the Label

Even before testing, do a quick label check for:

  • "Cold Pressed" clearly mentioned
  • No added preservatives or chemicals
  • Details of seed sourcing
  • Manufactured by a reputable company like oRegion
