How to Remove Cotton Phenol from Cottonseed Oil
Crude cottonseed oil contains gums and waxes (the amount varies depending on the amount of outer husk contained in the oiled kernel) and is of poor quality.
In addition, unrefined cottonseed oil is not recommended for consumption because of the presence of cotton-phenol (about 1%), which is toxic to reproduction.
Cotton phenol and other impurities can be effectively removed by oil refining equipment to ensure the safety and quality of the oil. As cotton phenol is weakly acidic, in the process of deacidification, and alkali reaction to generate cotton phenol sodium salt, soluble in water,insoluble in organic solvents. cotton phenol can be attached to the soap horn, the other impurities in the vegetable oil is also adsorbed, in the precipitation and separation of discharged from the oil.
Therefore, refining cottonseed oil must use alkaline refining process to ensure the safety of cottonseed oil consumption National health standards require that the cotton phenol content in oil is less than 0.02%.There is no effect on human body when the cotton phenol in cotton oil is not higher than 0.02%.
