Common specifications for
Super Activated Carbon
These are some common specifications for activated carbon powder used in edible oil purification
Particle size
The particle size of activated carbon powder used in the edible oil industry is typically fine, with an average particle size ranging from 44 to 74 microns.
Ash content
The ash content of activated carbon powder used in the edible oil industry should be low, typically <10%. Higher ash content can affect the quality of the oil and may result in increased foaming during processing.
Moisture content
The moisture content of activated carbon powder used in the edible oil industry should be low, typically less than 10%. Higher moisture content can lead to the growth of bacteria and other microorganisms, which can affect the quality of the oil.
Iodine number
The iodine number of activated carbon powder used in the edible oil industry is typically high, ranging from 800 to 1200 mg/g. A higher iodine number indicates a greater adsorption capacity and is an important factor in the effectiveness of the activated carbon powder for oil purification.
pH
The pH of activated carbon powder used in the edible oil industry should be neutral or slightly acidic, typically ranging from 6.5 to 7.5. This helps to ensure compatibility with the oil and prevent any negative impacts on the flavor or aroma of the oil.
Heavy metal content
The activated carbon powder used in the edible oil industry should be free from heavy metals such as lead, arsenic, and mercury, which can be harmful if ingested.
