Spot Fake Mustard Oil: Easy Tests to Ensure Purity at Home

• White Paper Test: Pure oil leaves a deep yellow, sticky stain; adulterated oil lightens or spreads.
• Iodine Test: Add 2 drops of iodine; pure oil's color won't change, blue/black indicates starch adulteration.
• Color & Aroma: Genuine oil is light/dark yellow with a strong pungent smell; fake is too bright/transparent or has a faint/no smell.
• Rubbing on Palm: Pure oil gives a pungent smell without leaving color; fake leaves yellow color or a chemical smell.
• Heating & Packaging: Genuine oil smokes strongly with a pungent aroma when heated. Always check FSSAI, expiry, and packaging for authenticity.

Why It Matters: Use simple home tests and check packaging to easily identify pure mustard oil and avoid adulteration.
