Mustard Oil vs Canola Oil, What Actually Differs (2026)

Last updated: 30 September 2026

> Quick Answer: The deciding difference in mustard oil vs canola oil is erucic acid: canola sits below 2%, mustard oil near 41 g per 100 g. Canola also carries more oleic acid. Mustard oil keeps the pungency that tadka and pickles depend on, which canola does not have.

Canola wins the erucic column outright. There's no honest way to argue otherwise. USDA FoodData Central lists ordinary mustard oil at 41.18 g of erucic acid per 100 g and canola at effectively none, because canola was bred in Canada specifically to remove it. A high oleic mustard seed narrows that gap without closing it.

Mustard oil's case is flavour and fit. Kachi ghani oil carries allyl isothiocyanate, the compound behind its heat, and that's why it sits in Indian tadka and achaar at all. Canola has no pungency whatsoever.

Is canola oil the same plant as mustard oil?

No. They're cousins in the Brassica family, not one crop. Canola comes from rapeseed, mainly Brassica napus, bred in Canada in the 1970s to carry under 2% erucic acid. Most Indian mustard oil comes from Brassica juncea, the raya or rai crop grown across Rajasthan, Haryana and Punjab.

The name itself is a standard, not a species. "Canola" denotes seed whose oil carries less than 2% erucic acid, as a 2017 comparative study in the International Journal of Chemical Studies notes. India has since bred mustard to that standard too: ICAR-IARI's Pusa Double Zero Mustard 31 carries under 2% erucic acid, but it is a separate variety and not what most Indian mustard oil is pressed from.

How much erucic acid does each oil carry per 100 g?

Canola carries effectively no erucic acid, ordinary mustard oil about 41 g per 100 g, and the SatRas high oleic mustard oil 23.85 g on its published laboratory report. Every row below is a separate product with its own source. None of the figures transfers from one oil to another.

Read the high oleic row as it stands. At 23.85 g the high oleic oil carries roughly half the erucic acid of generic mustard oil and still about twelve times the 2% canola ceiling. That is not a low erucic oil. Nobody should sell it as one.

What does the Raya Hisar 1706 seed change against canola?

It moves mustard oil toward canola on oleic and erucic acid without arriving there. Raya Hisar 1706 is a mustard variety developed by CCSHAU, Hisar. Its oil measures 25.75 g of oleic acid per 100 g on the published NIFTEM report, against the 12 to 15 g typical of generic mustard oil.

That is the case for the high oleic mustard oil pressed from Raya Hisar 1706, grown on SatRas's own farms in Hisar: more oleic acid, about half the erucic acid of ordinary mustard oil, and the mustard flavour kept intact. Canola still carries 61.74 g of oleic acid per 100 g against the high oleic oil's 25.75 g. The background on the Raya Hisar 1706 variety covers how the seed was bred and what the NIFTEM report tested.

Which oil suits Indian tadka and high-heat cooking?

Mustard oil suits tadka, achaar and slow-cooked North and East Indian dishes, because its pungency is part of the recipe. Canola suits baking, dressings and dishes where you want no flavour from the oil at all. Both are used for frying, and neither choice is about smoke point alone.

A smoke point of 250°C is commonly cited for mustard oil in reference tables, including a 2025 review in Frontiers in Nutrition, but the figure moves with refinement and free fatty acid content. Kachi ghani oil also needs heating to a shimmer before use to soften its raw bite, a step canola never needs. The comparison of mustard oil and refined oil covers the refining trade-off in more detail.

Which is easier to buy and use in an Indian kitchen?

Mustard oil, by a wide margin. It is grown, pressed and sold across North India, in every size from 1 L bottles to 15 kg tins, and most kitchens already cook with it. Canola is a niche oil on Indian shelves, usually sold refined.

On price, the SatRas high oleic mustard oil costs ₹359 for 1 L (list ₹735). A family using about 1 L a month spends that on its main cooking fat. Canola prices vary widely by pack and importer, so compare the per-litre figure on the shelf in front of you rather than a quoted average.

What did the 2017 comparative study measure beyond fatty acids?

The 2017 study measured tocopherols and sterols as well as fatty acids. It reported 38.32 mg of tocopherol per 100 g in its mustard oil sample, along with 606.32 mg of sterols, lower than other rapeseed oils it referenced. Its framing favours mustard oil more strongly than a single sample supports.

For scale, USDA lists canola at 17.46 mg of alpha-tocopherol per 100 g. The two are not directly comparable, one being total tocopherols and the other a single form, so treat the point as suggestive. One sample does not make a verdict.

What should you avoid when comparing canola and mustard oil?

Be wary of any comparison that moves a number from one oil to another, or treats "mustard oil" as a single product. Erucic acid alone ranges from under 2 g to over 40 g per 100 g depending on the seed. These are the errors that recur most often.

• Calling any mustard oil low erucic unless it is a double-zero variety tested below 2%.
• Quoting generic mustard figures for a named product, or a named product's figures for mustard oil in general.
• Treating smoke point as a safety ranking. It shifts with refinement and reuse.
• Swapping canola into achaar. Without pungency and its preservative bite, the pickle changes character.
• Reading one study as a verdict. The 2017 comparison tested one sample of each oil.

What does the evidence on erucic acid not settle?

It does not settle what everyday cooking amounts of erucic acid do to people. The concern comes largely from animal studies, which is why the US FDA's Import Alert 26-04 stops expressed mustard oil being sold there as a cooking oil. Human evidence is thinner and harder to read.

The European Food Safety Authority set a tolerable daily intake for erucic acid in 2016, also from animal data. The fuller picture, including where India's own standards sit, is on the page on mustard oil erucic acid safety. What the numbers here do settle is narrower: canola carries far less erucic acid than any mustard oil sold in India today, high oleic included.

Frequently asked questions

Can canola stand in for mustard oil in Indian recipes?

In some dishes, yes. Canola works for frying, sauteing and any recipe where the oil should add no taste of its own. It cannot replace mustard oil where pungency is the point, as in achaar, Bengali fish curries or a sarson ka saag tadka, because it carries none of the allyl isothiocyanate that gives mustard oil its bite.

Why is mustard oil sold for external use only in the US?

Because the US FDA does not permit expressed mustard oil to be sold as a cooking oil, citing its erucic acid content and animal study findings. Bottles sold there carry external-use labels as a result. The rule is a regulatory position based largely on animal data, and it applies to ordinary high-erucic mustard oil.

Can canola oil be used to make achaar?

It can be used, but the result is a different pickle. Traditional North Indian achaar relies on mustard oil's pungency for flavour and on the oil layer to cover the vegetables. Canola covers them just as well but adds no heat, so the pickle tastes flatter. Salt, acidity and clean, dry jars matter more for keeping quality than the oil type.

How does rapeseed oil relate to canola oil?

Canola is one kind of rapeseed oil, not a synonym for all of it. It meets a standard of under 2% erucic acid, set when Canadian breeders developed it in the 1970s. Older or industrial rapeseed oil can carry far higher erucic acid. In Europe, food-grade rapeseed oil is usually of the low erucic type, which is why the names get used loosely.

Does frying or reheating change mustard oil's erucic acid content?

No meaningful reduction has been shown. Erucic acid is a stable long-chain fatty acid that normal cooking temperatures do not break down, so the level in the bottle is broadly the level in the pan. Heating to a shimmer before use softens the pungency, which comes from a different compound altogether.

Which oil keeps longer once opened?

Both keep for several months in a cool, dark cupboard with the cap tightly closed. Refined canola is usually slightly more shelf-stable because refining removes compounds that go rancid. Unrefined kachi ghani oil can develop off notes sooner if left warm or exposed to light, so buying a size you finish within a few months is the practical rule.
