In recent years, with the increasing attention to food safety and health, the choice of edible oil has become more and more important. Leaching method is a common edible oil production process, which refers to the extraction of edible oil by solvent extraction. However, many people have doubts about the safety of edible oil produced by leaching method. So, is the edible oil produced by leaching method safe?

First of all, we need to know the process of producing edible oil by leaching. Leaching is a process of degreasing vegetable oil by using organic solvents (such as n-hexane). In this process, vegetable oil goes through the steps of soaking, degreasing, solvent evaporation and desolventizing, and finally edible oil is obtained. Compared with the traditional pressing process, the extraction method can improve the extraction rate of oil, thus improving the production efficiency.
However, because the leaching method uses organic solvents, many people are worried about the safety hazards of edible oil produced by leaching method. Organic solvent residue, solvent volatilization, oil stability and other issues have become the focus of attention.
In order to solve these problems, the relevant state departments have formulated strict production standards and regulatory measures for edible oil to ensure that the edible oil produced by leaching method meets the safety standards. First of all, in view of the problem of organic solvent residue, the state has stipulated the maximum allowable amount of organic solvent residue in edible oil, and conducted regular sampling inspection on production enterprises. Secondly, in view of the problem of solvent volatilization, production enterprises must strictly control the environment and conditions of solvent volatilization in the production process to ensure that products meet safety standards. In addition, in view of the stability of oil quality and other issues, the state has also made detailed regulations on the quality indicators of edible oil to ensure the stable and reliable product quality.
In addition to national regulatory measures, consumers can also judge the safety of edible oil produced by leaching method through the following points when purchasing edible oil: first, choose formal channels to buy products with qualified certificates and inspection reports; Secondly, pay attention to whether the packaging of the product is intact and avoid buying products that have been opened or damaged; Finally, pay attention to the production date and shelf life of products and avoid buying expired products.
Generally speaking, in solvent extraction plants, it is a common method to produce edible oil by leaching. The edible oil produced by leaching method is safe in strict compliance with national standards and regulatory measures. Consumers also need to choose formal channels when buying, and pay attention to the quality identification and packaging of products. Only in this way can the safety and health of edible oil be ensured.
