In the edible oil processing industry, cold pressing, hot pressing, and solvent extraction are the three most common methods. With years of manufacturing experience, we understand that first-time investors often face these questions:
Is cold pressing truly more nutritious?
Does hot pressing cause excessive nutrient loss?
Is solvent extraction too costly to invest in?
Below, we will provide a systematic analysis of these methods from three aspects: processing principles, advantages and disadvantages, and suitable applications.
Cold pressing involves extracting oil at low temperatures without high-heat treatment.
Advantages:
Maximizes retention of nutrients like Vitamin E and polyunsaturated fatty acids
Produces clear, natural-tasting oil
No chemical processing, meeting the demand for natural and healthy oils
Applications: Olive oil, flaxseed oil, walnut oil, grape seed oil, and other premium oils
Disadvantages: Lower yield and higher cost per unit
Ideal for: Small-scale boutique oil producers and high-end oil brands
Hot pressing involves steaming or roasting raw materials before pressing.
Advantages:
Higher oil yield for better production efficiency
Rich aroma preferred by most consumers
Mature technology with moderate investment
Applications: Peanut oil, rapeseed oil, sesame oil, soybean oil, and other common edible oils
Disadvantages: Some nutrients may be lost due to high temperature
Ideal for: Small to medium-sized oil mills aiming for a balance of cost and quality
Solvent extraction uses food-grade solvents to thoroughly extract oil, followed by refining to remove residual solvent and impurities.
Advantages:
Highest oil yield, with residual oil in the meal below 1%
Suitable for continuous, automated large-scale production
Lowest unit cost when scaled
Applications: Soybean oil, sunflower oil, rice bran oil, cottonseed oil, and other bulk vegetable oils
Disadvantages: High initial investment; requires proper refining equipment and safety compliance
Ideal for: Large oil factories or businesses planning to expand production
Want premium, nutrient-rich oils → Cold Press
Want aroma, reasonable cost, and stable yield → Hot Press
