Is Your Mustard Oil Pure? Quick Home Tests to Spot Adulteration Instantly

• White Paper Test: Pure oil leaves a dark yellow, sticky stain; adulterated oil spreads or leaves a light stain.
• Iodine Test: Add 2 drops of iodine; pure oil shows no color change, but adulterated oil turns blue or black.
• Smell & Rubbing Test: Pure mustard oil has a strong, pungent smell and leaves no color on hands; fake oil has a faint smell or leaves yellow color/chemical smell.
• Heating & Taste Test: Genuine oil produces strong smoke and pungent smell when heated, and a slight burning taste when raw; adulterated oil has milder reactions.
• Packaging Check: Always inspect packaging for damage, and verify brand, expiry date, and FSSAI number to avoid buying adulterated oil.

Why It Matters: Simple home tests and careful packaging checks can easily help identify pure mustard oil from adulterated versions.
