Why does edible oil decolorization need to be done under vacuum?

Vacuum decolorization process is a critical step in edible oil refining, used to remove unwanted pigments, trace metals, and contaminants. When these compounds remain in the edible oil, they can affect the taste, color, and stability of edible oil. But what makes vacuum conditions so crucial for achieving the best edible oil refining results?

Under vacuum, the edible oil decolorization process operates at lower temperatures, which protects the edible oil from oxidation—a common cause of spoilage, off-flavors, and a reduction in shelf life. Unlike traditional methods, edible oil vacuum decolorization preserves the oil’s natural nutrients and enhances its clarity and purity. This means your customers get an edible oil that not only looks clearer but also retains the health benefits they seek.

Besides, edible oil vacuum decolorization process of our Henan Glory Company also provides another significant benefit: it uses less energy. The lowered boiling points achieved under vacuum help minimize thermal stress, reducing energy consumption and keeping the decolorization process sustainable.
