A process for removal of contaminants from marine and vegetable crude oils containing health hazardous amounts of contaminations, comprising the steps of: mixing a first absorbent material intimately into the oil until a homogenous suspension is obtained, mixing a second absorbent material intimately into the obtained suspension until a homogenous suspension is obtained, allowing the final suspension to rest, separating the oil phase from the absorbent materials with bound contaminants, and collecting the purified oil. The invention also comprises steps to produce the crude oil from a marine or vegetable raw material. The purified marine or vegetable oil is suited for use in food products for human and animal consumption.
