As global attention to sustainable development intensifies, the oil extraction industry is facing increasingly severe environmental protection pressure and market competition challenges. Traditional extraction methods have problems such as low efficiency, high energy consumption and large impact on the environment. There is an urgent need to find more efficient and environmentally friendly solutions.
Commonly used methods for oil extraction mainly include:
Mechanical pressing technology separates oil from raw materials through physical means. Its advantage is that the extracted oil has high purity, does not use chemical solvents, and has excellent environmental performance. Relatively speaking, its extraction efficiency is low, especially when processing high-oil embryo raw materials, the cost will increase significantly.

Solvent extraction is the separation of oils and fats from raw materials through the use of chemical solvents. The advantage is that the extraction efficiency is high, especially suitable for raw materials with low oil content. However, the use of solvents will also cause environmental pollution problems, which requires strengthening the recovery and treatment of solvents.
Supercritical fluid extraction uses solvents in a supercritical state to extract high-purity oils without using harmful chemicals. Although this technology requires high equipment investment, its environmental advantages and efficient extraction characteristics have gradually won recognition in the industry.
Globally, the demand for healthy oils and fats continues to rise, and consumers are increasingly demanding product quality and safety. Therefore, enterprises should pay close attention to market dynamics, actively adapt to this change, and explore the application of emerging technologies and methods.
For example, as vegetable oil consumption trends change, more and more companies are beginning to test joint extraction technology, combining multiple extraction methods to improve overall efficiency and purity.
To sum up, modern oil extraction technology is facing the dual challenges of technological innovation and market upgrading. Enterprises need to proactively adapt to changes in market demand, analyze the advantages and disadvantages of different extraction methods, select the most suitable extraction solution for their own development, and refer to the opinions of industry experts in the decision-making process.
