The role of decolorization in oil refining
2024-05-29
Decolorization is a process in the oil production process of oil refining equipment and is used to produce high-quality edible oil. Oil decolorization usually use adsorbents for adsorption and decolorization. Commonly used adsorbents include activated clay, activated carbon, etc. What role does decolorization play in oil production? Oil refining equipment manufacturer-Jiangsu Honggang will introduce to you:
The role of oil refining and decolorization:
The oil refining and decolorization process can remove carotenoids, chlorophyll and other pigments in oil, and improve the color of oil to meet consumers' preference for light-colored oil products.
During the production, storage and transportation of oil, oxidation will occur, and the oxidation products will decompose to form secondary oxides, such as aldehydes, ketones, epoxides, etc. These oxidation products can be removed through the decolorization process, which can improve the oxidation stability of oil.
The decolorization process is one of the important processes in oil refining equipment. Decolorization is a standardized process before deodorization, and it is also a gateway for removing impurities before the oil is subjected to high temperature treatment. The decolorized edible oil not only improves the color, but also removes unwanted by-products in the oil, including certain harmful substances that are not conducive to food safety and hygiene, such as polycyclic aromatic hydrocarbons caused by pollution, pesticide residues, oxidation Metamorphic substances, etc. The decolorization process provides qualified raw oil for the next deodorization process. During refining, even if the color of the crude oil is lighter, it still needs to be decolorized to prevent the flavor of the fully refined edible oil from being affected.
