The food enzyme catalase (EC 18.104.22.168) is obtained from porcine liver by Laboratorios Arroyo S.A. It is intended to be used in a broad range of food processes. The Panel noted that the manufacturing process involved the use of a solvent not permitted in the production of food ingredients which include food enzymes. In addition, the evidence provided showed that the manufacturing process could not be guaranteed to inactivate viruses originating from the starting material, including the human zoonotic pathogen Hepatitis E virus. Consequently, the Panel concluded that the use of catalase extracted from porcine liver may present a health risk.
