Pig kidney protein extract Diamine oxidase DAO

The protein extract is obtained from homogenised pig kidneys through a combination of salt precipitation and high speed centrifugation. The obtained precipitate contains essentially proteins with 7 % of the enzyme diamine oxidase (enzyme nomenclature E.C. 1.4.3.22) and is resuspended in a physiologic buffer system. The obtained pig kidney extract is formulated as encapsulated enteric coated pellets or enteric coated tablets to reach the active sites of digestion.

The maximum level of protein extract from pig kidneys as a novel food currently authorised to be used in enteric coated encapsulated pellets in foods for special medical purposes, and in food supplements, is 3 capsules/day, corresponding to 12,6 mg pig kidney extract a day. The proposed use of the enteric coated tablets form will not alter the currently authorised maximum level of the novel food. Therefore, it is appropriate to amend the section of the Union list on the conditions of use of protein extract from pig kidneys to authorise its use also in enteric coated tablets form at the same maximum authorised level as the already authorised forms of use of this novel food.
