Oils are an important part of a balanced diet. They not only provide valuable fats, but also essential fatty acids and fat-soluble vitamins such as vitamin E, K or A. Vegetable oils, including hemp oil, flaxseed oil, rapeseed oil or olive oil, are used in both cold dishes and cooking. There is a fundamental difference between cold-pressed and refined oils, which affects nutrient content, taste and areas of application.
Cold-Pressed Oils
Production
Cold-pressed oils are obtained from seeds, nuts or fruits through mechanical pressing. No additional heat above 40–50°C is used. This gentle extraction largely preserves natural ingredients.
Nutrient Profile
-
Essential fatty acids: Omega-3, Omega-6 and in some cases Omega-9
-
Vitamins: Especially Vitamin E, sometimes also Vitamin K
-
Secondary plant compounds: Polyphenols and antioxidants
Advantages
-
Intense, natural taste (nutty, fruity, grassy)
-
Nutrient-rich and unadulterated
-
Ideal for cold applications where taste and nutrient content are preserved
-
Supports the stability of sensitive fats in the body through antioxidant compounds
Examples
Refined Oils
Production
Refined oils are produced through a combination of mechanical pressing and chemical or thermal treatment. The aim is to neutralize odor, color and taste and to increase shelf life.
Nutrient Profile
Advantages
-
Heat stable – suitable for frying, deep-frying and baking
-
Neutral taste, versatile in the kitchen
-
Longer shelf life
Disadvantages
-
Fewer natural nutrients and bioactive ingredients
-
Significantly less intense in taste
-
Some processing steps may leave small amounts of chemical residues
Application Tips
-
Cold-pressed oils: Ideal for dressings, bowls, smoothies, dips and for finishing cooked dishes.
-
Refined oils: Optimal for cooking processes at higher temperatures, e.g., frying, baking, deep-frying.
-
Combination: In the kitchen, both oils can be combined – cold-pressed oils for flavor and nutrients, refined oils for heat stability.
Storage
-
Cold-pressed oils: Sensitive to light and heat, should be stored in dark bottles in a cool, dry place; keep refrigerated after opening.
-
Refined oils: Less sensitive to light and heat, longer shelf life, but also need to be protected from direct sunlight.
Health Aspects
-
Cold-pressed oils provide unsaturated fatty acids that are essential for cardiovascular health, brain function, and skin health.
-
Refined oils may remain more stable with frequent high heat, but contain fewer bioactive components.
-
A mixture of both oil types can optimally combine taste, nutrient supply, and cooking flexibility.
Conclusion
Cold-pressed oils excel in nutrient density, taste, and health benefits, but are less suitable for heavily heated dishes. Refined oils are heat-stable, tasteless, and practical for everyday use, but contain fewer natural ingredients. By deliberately combining both variants, a balanced diet can be achieved that covers both enjoyment and functionality.
