How to Choose Pure Sarson ka Tel: A Buyer's Guide

Mustard oil is one of the most commonly adulterated cooking oils in South Asia. Loose oil sold from open containers can be mixed with cheaper oils, and in serious cases with harmful substances. Food authorities in the region have long warned about mustard oil contaminated with argemone oil, which comes from a weed whose seeds look similar to mustard seeds and can cause serious illness.

You can't run a lab test in your kitchen, but you can make much safer choices. Here's what to look for.

1. Avoid loose oil from open containers

The biggest risk is unbranded, loose oil. You don't know where it was pressed, what it was mixed with or how long it has been sitting there. Buy oil in sealed, labelled bottles from a brand that puts its name and address on the label and can be contacted if something is wrong.

2. Read the label carefully

• Ingredients: pure sarson ka tel has one ingredient, mustard seed oil. Words like "blended" or "mixed edible oil" mean it isn't pure mustard oil.
• Extraction method: look for "kachi ghani" or "cold pressed".
• Manufacturer details: a real address and contact number are a good sign.
• Batch and dates: check the packing or expiry date.

3. Use your nose and eyes

Pure kachi ghani mustard oil has a natural golden to amber colour and a strong, sharp aroma that you notice the moment you open the bottle. An oil that looks very pale and smells weak is probably refined, blended, or both.

4. Be suspicious of prices that are too good

Mechanical pressing gets less oil out of each kilo of seed than industrial solvent extraction, so genuine kachi ghani oil costs more to produce. If a "pure" mustard oil is far cheaper than everything else on the shelf, ask yourself how.

What about the home tests on social media?

You'll find videos showing a "fridge test", a "rubbing test" or mixing oil with chemicals at home. Be careful with these. Most are unreliable, and some give false reassurance. Results can change with temperature, with the type of mustard seed, and with how the oil was processed. The only dependable way to confirm purity is testing in a proper food laboratory.

That is why buying from a transparent, traceable source matters more than any kitchen trick.

5. Choose a brand that shows its process

A trustworthy producer should be able to tell you where its seed comes from, how the oil is pressed, and how it is filtered and packed. If a brand can't answer those questions, keep looking.
