Knowledge base
Sunflower oil owes its properties primarily to an exceptional fatty acid profile – a dominant content of linoleic acid (omega-6) and the natural presence of vitamin E, mainly in the form of alpha-tocopherol. It is one of the most widely used vegetable oils in the food industry and foodservice sector, valued for its neutral flavour, raw material availability and broad range of applications.

Sunflower Oil Properties – Chemical Composition and Technical Parameters
Sunflower oil properties are rooted in the fatty acid profile, which fundamentally differentiates its two main technological variants. Standard sunflower oil (the so-called linoleic type) contains 48–75% linoleic acid (C18:2, omega-6) and approximately 15–40% oleic acid (C18:1, omega-9). The high oleic (HO) variant reverses these proportions: oleic acid accounts for over 78% of the composition, which fundamentally alters the oxidative stability of the product.
Key technical parameters of sunflower oil:
| Parameter | Linoleic oil (standard) | High oleic oil (HO) |
| Linoleic acid (C18:2) | 48–75% | <15% |
| Oleic acid (C18:1) | 15–40% | >78% |
| Smoke point | 220–230°C | 220–230°C |
| Oxidative stability (OSI, h) | Low–medium | High |
| Vitamin E (tocopherols) | 400–700 mg/kg | 200–400 mg/kg |
| SFA content | approx. 10–12% | approx. 8–10% |
Vitamin E and Tocopherols – The Natural Antioxidant in Sunflower Oil
Linoleic sunflower oil is one of the richest sources of alpha-tocopherol among vegetable oils – tocopherol content reaches 400–700 mg/kg, providing natural protection against oxidation over a short storage horizon. In the high oleic variant, the tocopherol content is lower; however, the higher proportion of oleic acid – considerably more resistant to oxidation than omega-6 – significantly increases stability in terms of shelf life for finished food products.
What Is Sunflower Oil Used For? Applications in Industry and Foodservice
What sunflower oil is used for in industrial practice is a question with a specific, technical answer. Sunflower oil finds application in deep frying, production of sauces and salad emulsions, bakery and confectionery products, margarines, industrial frying fats, and as a base oil in ready-to-eat products. Its neutral flavour profile makes it a versatile raw material that does not interfere with the sensory characteristics of the final product.
Applications of sunflower oil by variant:
- Linoleic oil (standard): dressings, salad sauces, mayonnaise, margarines, table oils, products requiring visible omega-6 content on the label
- High oleic oil (HO): deep frying and industrial frying, frying fats, crisps and snacks, applications requiring extended shelf life and a high smoke point
Applications of Sunflower Oil in the HoReCa and Foodservice Segment
In foodservice and the HoReCa segment, sunflower oil serves as a versatile raw material – from pan frying through the preparation of marinades and dressings to cold emulsions and sauces.
Its flavour neutrality is a particular advantage here: the oil does not dominate the sensory profile of the dish, which in a professional kitchen has measurable implications for recipe consistency.
Sunflower Oil for Frying – Is It Suitable for Frying and Under What Conditions?
Sunflower oil is suitable for frying, but the fatty acid profile determines its suitability. Standard linoleic sunflower oil, despite refining, contains a high proportion of linoleic acid (PUFA), which makes it less stable during prolonged frying; it is more susceptible to oxidation and polymerisation, shortening the service life of the frying bath and reducing the quality of the final product. The high oleic variant, with a predominance of oleic acid (MUFA), exhibits considerably higher oxidative resistance and is therefore better suited for frying at elevated temperatures and in continuous processes. The smoke point of refined oils of both types is similarly around 225–232°C; consequently, differences in frying stability are due primarily to the fatty acid composition rather than to the smoke point itself.
Is Sunflower Oil Suitable for Frying Chips?
Whether sunflower oil is suitable for frying chips depends directly on which variant is being considered. Standard linoleic sunflower oil is not recommended for continuous deep frying of chips: its low oxidative stability shortens the service life of the frying bath and generates excessive operating costs. For frying chips in foodservice and industrial production, the appropriate choice is high oleic sunflower oil (HO) or a dedicated industrial frying fat, both of which have a smoke point above 220°C and a considerably longer service life in the frying process.
Sunflower Oil for Frying – Practical Selection Criteria
Whether sunflower oil is suitable for frying depends on the type of process:
- ✓ Short-duration pan frying up to 180°C (vegetables, eggs, pancakes) – linoleic oil is suitable
- ✓ Single-use frying, without repeated reheating of the same batch – acceptable
- ✗ Prolonged deep frying, industrial fryers – linoleic oil is not recommended
- ✗ Processes above 200°C – excluded for linoleic oil
Is Sunflower Oil Suitable for Baking? Applications in Bakery and Confectionery
Whether sunflower oil is suitable for baking – the answer is affirmative within the temperature ranges typical of baking processes. Sunflower oil used for baking at 160–180°C performs well: in sponge cakes, muffins and leavened products it acts as a moisture carrier, a crumb-softening agent and a component that improves batter spreadability. Its neutral flavour profile does not interfere with the sensory characteristics of the product, which is an advantage in industrial bakery and confectionery production.
Sunflower oil for baking is used in, among others:
- sponge cakes and shortcrust pastry
- confectionery masses and fillings
- products requiring a soft, elastic crumb texture
- wafer production (in combination with confectionery fats)
How Many Calories Does Sunflower Oil Have? Calorie Content and Nutritional Values
The calorie content of sunflower oil is a parameter relevant both for nutritional declarations on packaging and for recipe calculations. Sunflower oil provides approximately 884–900 kcal per 100 g. Calculations use the standard energy factor for fat of 9 kcal/g, in accordance with the principles applied in the EU for food labelling.
Nutritional values of sunflower oil (per 100 g):
| Component | Linoleic oil | High oleic oil (HO) |
| Energy | ~900 kcal / 3,700 kJ | ~900 kcal / 3,700 kJ |
| Total fat | 100 g | 100 g |
| – of which saturated | approx. 10–12 g | approx. 8–10 g |
| – monounsaturated | approx. 14–40 g | approx. 80 g |
| – polyunsaturated | approx. 50–70 g | approx. 5–10 g |
| Vitamin E (alpha-toc.) | 40–60 mg | 20–40 mg |
| Cholesterol | 0 mg | 0 mg |
Is Sunflower Oil a Good Industrial Raw Material? Technical Assessment
Whether sunflower oil is a good industrial raw material depends on the application context and process requirements. Sunflower oil is an optimal raw material wherever a neutral flavour profile, clean label, raw material availability and competitive pricing are required. In cold applications and at moderate temperatures it is difficult to replace. In processes requiring high thermal stability, standard linoleic oil has limitations that are addressed by the high oleic variant or dedicated industrial frying fats.
FAQ – Sunflower Oil Properties and Applications
Does sunflower oil have a taste and odour?
Refined sunflower oil is practically odourless and tasteless – a desirable characteristic in industrial production, where the oil should not dominate the sensory profile of the finished product. Cold-pressed (unrefined) oil has a characteristic, slightly nutty aroma and flavour, which precludes it from most industrial applications.
What is the difference between linoleic and high oleic sunflower oil?
Linoleic oil contains 48–75% linoleic acid (polyunsaturated omega-6), has a comparable smoke point and is susceptible to degradation under intensive heating. High oleic (HO) oil contains over 78% oleic acid (monounsaturated omega-9), has a smoke point above 220°C and significantly higher oxidative stability – it is recommended for industrial frying and products with an extended shelf life.
Which sunflower oil should I choose for food production?
For deep frying and thermal processes above 180°C – high oleic (HO) oil or a dedicated industrial frying fat. For cold applications, dressings, emulsions and bread products – standard linoleic oil. The choice of raw material should always be discussed with a food technologist, taking into account the process temperature, required shelf life and certification requirements.
