The food enzyme catalase (hydrogen-peroxide:hydrogen-peroxide oxidoreductase; EC 18.104.22.168) is obtained from porcine liver by Avances Bioquímicos Alimentación, S.L. (Spain). The food enzyme is intended to be used in cheese production for decomposition of hydrogen peroxide in brine. The manufacturing process involves the use of a solvent not permitted in the production of foods and food ingredients according to Directive 2009/32/EC. Consequently, the food enzyme does not comply with the existing requirements in the EU.
