Hemp Seed Oil vs Rapeseed Oil: Quality, Nutrition, and Best Uses Compared
Should your next product use hemp seed oil or rapeseed oil? Both have their place, but picking the wrong one costs you — in flavour, nutrition, or production efficiency. This guide breaks down their fatty acid profiles, smoke points, processing methods, and best applications so you can decide with confidence.
Choose hemp seed oil when omega-3 content matters — it delivers roughly 20g of ALA per 100ml with a near-perfect 3:1 omega-3 to omega-6 ratio. Use it raw: dressings, dips, cold sauces. Choose rapeseed oil when you need a neutral oil that handles heat — it has the lowest saturated fat of any cooking oil and a smoke point up to 445°F / 230°C when refined. Use it for frying, baking, and any application where the oil plays a supporting role.
Hemp Seed Oil: Always Cold-Pressed
Hemp seed oil is made by cold-pressing the seeds of EU-certified hemp varieties. No heat, no chemicals — just mechanical pressing. What comes out is a deep green oil with a nutty, earthy flavour. It contains zero CBD or THC in meaningful amounts — well below the EU limit of 3 mg/kg. Nordic Hemp grows its hemp on over 5,000 hectares of Estonian farmland, cold-presses the oil on site, and holds EU Organic certification and BRCGS Food Safety certification.
Rapeseed Oil: Refined vs Cold-Pressed
Rapeseed oil comes from the seeds of Brassica napus, a plant in the mustard family with bright yellow flowers. It’s sold in two forms: refined (the standard cooking oil, also labelled as “vegetable oil”) and cold-pressed (sometimes labelled “extra virgin” or “culinary”). Modern rapeseed varieties are bred to be low in erucic acid, making them safe for human consumption. According to the British Heart Foundation, rapeseed oil has the lowest saturated fat content of any cooking oil and is high in heart-healthy monounsaturated fats.
Hemp Seed Oil vs Rapeseed Oil: Nutrition Comparison
| Nutrient (per 100ml) | Hemp Seed Oil | Rapeseed Oil |
|---|---|---|
| Total fat | ~100 g | ~100 g |
| Calories | ~884 kcal | ~884 kcal |
| Saturated fat | ~9 g | ~6.6 g |
| Monounsaturated (omega-9) | ~12 g | ~60 g |
| Polyunsaturated (omega-3 + omega-6) | ~79 g | ~29 g |
| Omega-3 (ALA) | ~20 g | ~9.6 g |
| Omega-6 (LA) | ~57 g | ~19.7 g |
| Omega-3:6 ratio | 3:1 | ~2:1 |
| Vitamin E | ~50 mg | ~22 mg |
| Smoke point | ~330°F / 165°C | ~400°F / 204°C (refined) |
A quick look at the numbers tells a clear story. With nearly 80% of its fat in polyunsaturated form, hemp seed oil is a nutritional powerhouse — omega-3 and omega-6 in a near-perfect 3:1 ratio. It delivers more than double the omega-3 of rapeseed oil and nearly twice the vitamin E. Rapeseed oil is dominated by monounsaturated fat (oleic acid), making it more stable at high temperatures, and has the lowest saturated fat content of any cooking oil.
Nutritional verdict. Choose hemp seed oil when omega-3 intake is the goal — for cold dishes, dressings, and functional foods where nutrition drives the purchase decision. Choose rapeseed oil when you need a versatile cooking fat with low saturated fat and high heat tolerance — for frying, baking, and everyday kitchen use where the oil plays a supporting, not starring, nutritional role.
Which Oil Has More Omega-3?
Hemp seed oil wins by a wide margin. It contains roughly 20g of alpha-linolenic acid (ALA) per 100ml — more than double the 9.6g found in rapeseed oil. Both oils also boast excellent omega-3 to omega-6 ratios (3:1 for hemp, ~2:1 for rapeseed), but the sheer quantity of omega-3 in hemp seed oil is unmatched by any common cooking oil except flaxseed oil.
For food manufacturers, this matters. A product made with hemp seed oil can carry a genuine omega-3 nutritional claim. Salad dressings, plant-based sauces, dips, and functional foods all benefit from its fatty acid profile.
Which Oil Is Better for Cooking?
Rapeseed oil, no contest. Its smoke point is around 400°F (204°C) when refined, and some varieties handle up to 445°F. That makes it suitable for frying, sautéing, roasting, and baking. Its neutral flavour won’t alter the taste of your food.
Hemp seed oil’s smoke point is around 330°F (165°C). Heat it beyond that, and you lose the delicate omega-3 fatty acids and develop a bitter taste. It belongs in cold dishes — dressings, dips, smoothies, drizzled over roasted vegetables after cooking, or mixed into hummus and pesto.
Cold-Pressed vs Refined: Processing Quality
This is where the two oils diverge most sharply. Cold-pressed, start to finish — that is how hemp seed oil is made. Mechanically pressed at low temperatures, the seeds retain their full range of fatty acids, vitamins, and antioxidants. No refining, no chemical solvents, no high-temperature deodorisation.
Rapeseed oil is usually refined. Producers crush the seeds, heat them to high temperatures, and treat them with chemical solvents like hexane to extract the maximum yield. From there, the crude oil is degummed, bleached, and deodorised — processes that strip away flavour, colour, and some nutrients. What you get is a shelf-stable, neutral-tasting oil that’s cheap to produce but nutritionally inferior to its cold-pressed form.
Cold-pressed rapeseed oil does exist, and it’s a better product. But it makes up a tiny fraction of the market. Most rapeseed oil on the shelf — including anything labelled simply “vegetable oil” — is highly refined.
No refining, ever. Every bottle of hemp seed oil is cold-pressed from start to finish.
Can You Substitute Hemp Seed Oil for Rapeseed Oil?
Not in cooking. If a recipe calls for rapeseed oil for frying or baking, hemp seed oil will burn and taste unpleasant. But in dressings, dips, and cold sauces, you can swap them freely — hemp seed oil adds more flavour and a much better omega-3 profile.
One tip: start with a 1:3 ratio (one part hemp seed oil to three parts rapeseed or olive oil) to ease into the nutty taste. Adjust from there.
Which Oil Is Better for Food Manufacturing?
Each oil has a clear role in commercial food production. The choice depends on what you are making and how you position it.
| Application | Hemp Seed Oil | Rapeseed Oil |
|---|---|---|
| Salad dressings & vinaigrettes | Excellent — adds omega-3 positioning and nutty flavour | Good — neutral base, lower nutritional claim |
| Mayonnaise & emulsified sauces | Works well cold, premium nutritional profile | Standard choice, stable emulsion, neutral taste |
| Plant-based dips (hummus, pesto) | Excellent — flavour and nutrition add value | Functional but no marketing advantage |
| Bakery products | Not recommended — heat degrades the oil | Excellent — heat-stable, neutral flavour |
| Fried snacks & crisps | Not suitable — smoke point too low | Excellent — high smoke point, industrial fryers |
| Margarine & spreads | Possible in cold blends, limited heat exposure | Traditional base fat for spreads |
| Functional foods & supplements | Excellent — genuine omega-3 claim possible | Minimal — fatty acid profile too common |
| Smoothies & beverages | Excellent — blends well, boosts omega-3 | Not used — flavour and positioning wrong |
For products where nutritional positioning drives purchasing decisions — think cold sauces, dressings, functional foods, and plant-based products — hemp seed oil offers a genuine omega-3 advantage that no refined oil can match. The 3:1 omega-3 to omega-6 ratio is a label-ready claim.
For high-volume applications that need a neutral, heat-stable oil — baking, frying, snack production — refined rapeseed oil is the standard across the European food industry. It has one of the lowest saturated fat contents of any cooking oil and performs reliably at scale.

Frequently asked questions
Is hemp seed oil healthier than rapeseed oil?
It depends on what you need. Hemp seed oil has more omega-3 (20g vs 9.6g per 100ml) and a near-perfect 3:1 omega-3 to omega-6 ratio. Rapeseed oil has the lowest saturated fat of any cooking oil and is better for high-heat cooking. Both can be part of a healthy diet.
Does rapeseed oil cause inflammation?
No. Modern evidence shows rapeseed oil does not cause inflammation. Older concerns were based on early research into omega-6 fatty acids, but more recent studies confirm that omega-6 fats do not increase inflammation when eaten as part of a balanced diet. The British Heart Foundation rates rapeseed oil as a heart-healthy choice.
Can you use hemp seed oil for baking?
Not recommended. The low smoke point (330°F / 165°C) means the oil degrades under sustained heat, losing its nutritional value and developing a bitter taste. For baking, use rapeseed or another high-smoke-point oil.
Which oil has a better omega-3 to omega-6 ratio?
Both are excellent. Hemp seed oil has a 3:1 ratio (omega-3 to omega-6), which is widely considered optimal for human health. Rapeseed oil has a ratio of roughly 2:1, also well within the recommended range. Most other vegetable oils have ratios of 10:1 or higher, heavily skewed toward omega-6.
