Safety evaluation of the food enzyme phytepsin from Cynara cardunculus L.

Abstract

The food enzyme phytepsin (EC 3.4.23.40) is extracted from the pistils of the cardoon (Cynara cardunculus L.) by seven manufacturers represented by the Regulation Council of Protected Designation of Origin Torta del Casar. It is intended to be used in milk processing for cheese production. As no concerns arose from the source of the food enzyme, from its manufacture, and based on the history of safe use and consumption, the Panelconsidered that toxicological data and the estimation of dietary exposure were not required. A search for similarity of the amino acid sequences of the food enzyme to known allergens was made and no matches were found. The Panelconsidered that allergic reactions to this phytepsin cannot be excluded in individuals allergic to this plant. However, the likelihood of allergic reactions to the phytepsin from C. cardunculus L. is expected not to exceed the likelihood of allergic reactions to cardoon. As the prevalence of allergic reactions to cardoon is low, also the likelihood of such reaction to occur to the food enzyme is low. Based on the data provided, the Panelconcluded that this food enzyme does not give rise to safety concerns under the intended conditions of use.
