Edible oils play an indispensable role in our daily cooking, and their quality directly affects the taste and health of food.
However, during the production process of edible oils, the oils often contain various impurities and harmful substances, such as polycyclic aromatic hydrocarbons (PAHs), which need to be effectively removed to ensure the safety and high quality of the oils.
Activated carbon, as a highly efficient adsorbent material, plays an irreplaceable role in the purification process of edible oils. This article will explore the application of activated carbon in the treatment of edible oils, especially its importance in removing PAH from edible oils.
Hazards Of PAHs In Edible Oils
Polycyclic aromatic hydrocarbons (PAHs) are a class of harmful chemical substances formed during incomplete combustion, and they are widely present in the environment and food, which may enter edible oils through various paths.
The PAHs in edible oils are mainly contaminated through food processing, especially high-temperature cooking processes, posing potential threats to human health.
Long-term consumption of edible oils containing PAHs may increase the risk of cancer, especially lung cancer and stomach cancer, and may also affect the taste and nutritional value of food.
Therefore, in order to reduce the harm of PAHs to the human body, activated carbon needs to be used to purify the edible oils.
Mechanism Of Activated Carbon In Removing PAHs From Edible Oils
We have learned about the dangers that PAH in cooking oil poses to our human health, next we will learn how activated carbon removes these harmful substances.
The role of activated carbon in removing polycyclic aromatic hydrocarbons (PAHs) from edible oils is based on its unique physical and chemical properties. Activated carbon has an extremely large surface area and a complex porous structure, which enables it to effectively adsorb hydrophobic compounds like PAHs.
At the same time, the non-polar characteristics of the activated carbon surface match the chemical properties of PAHs, enhancing the adsorption effect, while the phenolic, carboxyl, and other functional groups on the surface further promote the removal of PAHs through chemical interactions.
During the adsorption process, PAH molecules are physically fixed on the surface or pores of the activated carbon, and they may also interact with the chemical functional groups on the activated carbon surface, and these forces together effectively remove PAHs from the edible oils.
Advantages Of Activated Carbon In Removing PAHs
As a highly efficient and widely applied adsorbent, activated carbon has shown significant advantages in removing polycyclic aromatic hydrocarbons (PAHs) from edible oils.
Its unique physicochemical characteristics and high adsorption capacity make it an ideal choice for purifying edible oils and reducing the risk of PAH contamination. The following table are the advantages of activated carbon in removing PAHs from edible oils:
| Characteristic | Description |
|---|---|
| High Adsorption Efficiency | Activated carbon has a developed porous structure and large specific surface area, effectively capturing and fixing PAH molecules in oil. |
| Selective Adsorption | Activated carbon has high selectivity for organic pollutants like PAHs, preferentially adsorbing these harmful substances, thereby improving purification efficiency. |
Selecting Activated Carbon For Removing PAHs From Edible Oils
As a highly effective adsorbent, activated carbon plays a key role in the purification process of edible oils. Choosing the right activated carbon can ensure the effective removal of polycyclic aromatic hydrocarbons (PAHs) and other harmful substances from edible oils, while maintaining the natural flavor and nutritional value of the oils.
Wood powdered activated carbon is usually used to remove PAH from edible oils. This food-grade powdered carbon has different specifications, with the best iodine adsorption level, methylene blue value, and molasses value, designed specifically for edible oil purification, and can effectively remove harmful substances and odors.
Here are some parameters of this powdered activated carbon：
- Iodine value: 900-1000 mg/g
- Molasses value: 200-300 mg/g
- Particle size: 100 / 200 / 325 mesh
