In recent years, more and more pseudo-science health speech has made consumers unintelligible. Speaking of the most important cooking oil affecting the quality of the table of the people, it is necessary to mention the most widespread misunderstandings: 1. The pressing oil is better than the leaching oil; 2. The leaching oil is not nutritious and actually contains the carcinogen benzopyrene; All blending oils are not good. On September 26th, the China National Cereals and Oils Association Oil and Fats Branch held a special meeting to restore the truth and clarify the untrue words.
1. What are the advantages and disadvantages of the leaching process and the pressing process?
There are two kinds of edible oils, namely, the pressing method and the leaching method. The oils prepared by the pressing method or the leaching method are collectively referred to as "hair oil" at first, and are inedible because they contain impurities. From the oil to the refined oil, it must undergo degumming, deacidification, decolorization, deodorization and other processes. It can be seen that whether the edible oil is safe or not depends on whether the preparation of the front section is pressing or leaching, but is determined by the subsequent refining process. Therefore, there is no difference between the leaching process and the pressing process.
Second, the leaching process leads to nutrient loss and even carcinogens?
Regardless of the pressing or leaching, the nutrients in the oil are accompanied by the oil entering the oil. Similarly, if the quality of the oil is not good, the harmful ingredients will be brought into the oil. Therefore, the factors affecting the nutrition of edible oils are that the quality of raw materials should be guaranteed, and the refining process must conform to national standards.
Secondly, the leaching method adopts the extraction principle, which is essentially a physical dissolution process, and does not cause chemical reaction between oil and solvent. Therefore, if the leaching process uses a qualified solvent and is in accordance with national standards during the refining process, the refined oil is absolutely safe.
Third, the reconciliation oil is not good?
Blending oil is a scientific formula formulated with two or more oils. In 2016, the “Chinese Dietary Guidelines†issued by the National Health and Family Planning Commission emphasized the diversity of foods, which is no exception to edible oils. Therefore, the scientifically matched blending oil clearly contains a richer variety of nutrients and is superior to a single vegetable oil.
In addition, in some discussions on topics such as “GMO oilâ€, the participating experts also explained that since the genetically modified component in the genetically modified oil is based on protein and does not bind to fat, it is produced in the edible oil produced by the genetically modified oil. It is difficult to detect genetically modified ingredients, and consumers can safely eat them.
China's oil processing industry and oil market are generally healthy and upward. Edible oil products on the market are safe as long as they meet any of the grades of edible oil quality standards and hygiene standards. Consumers should learn to make rational judgments and avoid being misled by rumors.
