THE REMOVAL OF MOSH AND MOAH FROM VEGETABLE OILS

The removal of MOSH (Mineral Oil Saturated Hydrocarbons) and MOAH (Mineral Oil Aromatic Hydrocarbons) from vegetable oils is a matter of critical importance for food safety. These contaminants can enter oils through environmental exposure, processing equipment, transportation, and especially food packaging materials. Among them, MOAH poses a higher risk due to its potentially carcinogenic nature, while MOSH is known for its tendency to accumulate in the human body, making it a contaminant that must be strictly controlled. Therefore, during the processing of vegetable oils, it is essential to remove or minimize the presence of these substances.

Short Path Distillation (SPD) is an advanced refining technology used to effectively eliminate unwanted mineral oil residues such as MOSH and MOAH from vegetable oils. This method operates under vacuum conditions, enabling the precise separation of components while preserving the natural structure and quality of the oil, in contrast to conventional high-temperature techniques. Since MOSH and MOAH are more volatile than the main components of vegetable oils, they can be efficiently removed at lower temperatures and in shorter processing times using short path distillation.
