What are the methods for high-quality safflower seed oil production?

Safflower seed oil is not the same as the commonly used safflower oil found in first aid kits—it is a specialty oil extracted from safflower seeds through mechanical processing, refining, and purification. Rich in nutrients, safflower seed oil contains 6% saturated fatty acids, 21% oleic acid, and 73% linoleic acid. As linoleic acid is its main component—making it the highest among edible oils—safflower seed oil offers exceptional nutritional value. Additionally, it contains large amounts of vitamin E, oryzanol, phytosterols, and other medicinal compounds, earning it the reputation of a new-generation "healthy oil" or "nutritional health oil."

There are several processing methods for safflower seed oil, including pressing, solvent extraction, and pre-pressing followed by extraction. Each method requires different types of machinery. However, for this niche, high-end edible oil, cold pressing is the most widely accepted process among consumers.

The pressing method is a well-established technique that mechanically extracts oil from seeds through applied pressure. This process retains most of the natural nutrients and flavor of the safflower seeds, minimizes nutrient loss during processing, and is supported by mature equipment technology—making it ideal for producing premium edible oil.

Safflower seed oil production often employs low-temperature cold pressing technology. This process maximizes the preservation of natural nutrients and aroma while avoiding the generation of harmful substances that may arise during high-temperature processing.

Cold pressing typically occurs at temperatures no higher than 60°C. Compared to traditional high-temperature pressing, this method better preserves unsaturated fatty acids, vitamins, and antioxidants in the safflower seed oil, enhancing its nutritional value.

Once the crude safflower seed oil undergoes the refining process—including degumming, neutralization, and other key steps using advanced refining equipment—it meets China’s national first-grade edible oil standard. These steps remove impurities such as phospholipids, free fatty acids, waxes, and other harmful substances, resulting in improved oil color, quality, and food safety.

As a typical niche edible oil, safflower seed oil demands careful attention to its production process and the selection of processing equipment. When purchasing equipment, oil producers should thoroughly assess the manufacturer’s product quality and reputation—focusing on materials, process standards, and after-sales service. A comprehensive evaluation allows for the best choice of equipment and supplier.
