Edible oil is one of the indispensable and important foods in daily life, and its quality is directly related to people’s health and quality of life. In the refining process of edible oil, dewaxing process is a crucial technical link, which directly affects the appearance, stability and consumer experience of edible oil.

The dewaxing process can effectively improve the appearance of edible oil. The edible oil without dewaxing treatment is easy to produce white precipitates at low temperature, which are mainly waxy components with high melting point. Although these waxes are harmless to human body, they will affect the transparency and visual effect of edible oil and make consumers mistakenly think that there are quality problems in oil products. Through dewaxing process, these waxes can be removed, so that the edible oil remains clear and transparent at low temperature, thus improving the market competitiveness of products.

The dewaxing process can enhance the stability of edible oil. Waxy components may react with other components in oil during storage, resulting in the decline of the quality of edible oil. For example, wax may accelerate the oxidation process of oil, thus shortening the shelf life of edible oil. By dewaxing, these potential problems can be reduced, thus prolonging the storage time of edible oil and ensuring its stable quality.

The dewaxing process can also improve the consumer experience. In the cooking process, if the edible oil contains more wax, it may produce odor or smoke when heated, which will affect the taste and cooking environment of dishes. The dewaxed edible oil is purer and can provide consumers with a better cooking experience.

At present, the common dewaxing processes mainly include freeze dewaxing and solvent dewaxing. Freeze dewaxing precipitates wax by lowering the temperature, and then removes it by filtration; While solvent dewaxing uses solvent to dissolve wax and separate it. These methods have their own advantages and disadvantages, and the specific selection needs to be adjusted according to the characteristics and production requirements of different oils.

To sum up, dewaxing process is of great importance in edible oil refining. It not only improves the appearance and quality of edible oil, but also ensures the use experience and health needs of consumers. With the continuous progress of technology, the future dewaxing process will be more efficient and environmentally friendly, providing people with higher quality healthy edible oil.
