Refining Vegetable Oils: Chemical and Physical
This review presents recent technologies involved in vegetable oil refining as well as quality attributes of crude oils obtained by mechanical and solvent extraction. Sometimes the dewaxing process is added for types of
In the skin, shell and cell walls of vegetable oilseeds, such as corn germ oil, sunflower oil, and rice bran oil, there is a certain amount of wax. In the process of making oil, the wax will enter into the oil. Under the

These components must be removed to ensure oil transparency. Dewaxing or winterization are a critical process of oil refining in cold weather regions. The dewaxing or winterization process involves the cooling of oil to crystallize

Dry dewaxing also has its limitations, such as a maximum wax content of 900 ppm for the feedstock to pass the 24-hour cold test. To achieve effective wax removal, many edible oil producers now combine wet dewaxing and dry
This method is often used for dewaxing of vegetable oils. Process flow: Cooling crystallization: First, the pretreated oil is cooled to a low temperature of 5°C~10°C, and waxes and lipids begin to
Which oils need dewaxing treatment and what is the process?
Oil dewaxing treatment process during edible oil refinery is to remove the wax content in some kinds of crude edible oil, wax is a kind of polymer lipid, high melting point, poor solubility

Edible oil Refining De-Waxing / Winterization
Dewaxing or Winterization is a process to remove solids (saturated glycerides or waxes) from oil.These solids cause cloudiness in oil at low temperature. This process is suitable for oils like Sunflower Oil,

During the dewaxing process, the oil is cooled to cause the wax to crystallize, which it starts to do when the cloud point of the oil is reached. Good filtration characteristics, such as a
Winterization, also known as dewaxing, is one of the most important processes in the chemical-based refining of vegetable oils. Carried out in a facility for Dewaxing & Winterization of
- What is oil dewaxing treatment process during edible oil refinery?
- Oil dewaxing treatment process during edible oil refinery is to remove the wax content in some kinds of crude edible oil, wax is a kind of polymer lipid, high melting point, poor solubility in oil, will affect the taste and transparency of the edible oil, so the edible oil needs dewaxing treatment.
- What is vegetable oil de-waxing?
- Different vegetable oil and different processing methods result in different wax content. Oil de-waxing is separating the high melting wax and high melting solid fat by cooling and crystallization, and then removing them by filtration or centrifugal principle. It is a necessary process for making high-quality salad oil.
- Why is dewaxing important in oil refining?
- The dewaxing process is a crucial step in the oil refining industry, ensuring that oils, lubricants, and fuels perform optimally at low temperatures. By removing waxes that can cause oil to become thick and less fluid in cold conditions, the dewaxing process improves the flow characteristics and overall quality of oils.
- What is dewaxing & how does it work?
- Dewaxing is a refining process used to remove waxes from oils, especially lubricating oils, base oils, and fuels like diesel. The goal is to reduce the pour point (the lowest temperature at which the oil can flow), which is critical in applications where oils need to perform in low-temperature environments.
- What is winterization & dewaxing?
- Winterisation is another name to the process of dewaxing. The name winterization appears as during winter when the temperature is low, waxes present in the oil crystallizes, they give hazy appearance to the oil. Some oils are dewaxed before packing so as to remove waxes, which are dissolved in the oil.
- How do edible oil producers remove wax?
- To achieve effective wax removal, many edible oil producers now combine wet dewaxing and dry dewaxing processes in their refining plants. This combination enables oil producers to pass the 72-hour cold test. The dry dewaxing process involves mixing the oil with filter aid powder, followed by cooling and maturation.
