(6)Commission Implementing Regulation (EU) 2023/951note amended the specifications of protein extract from pig kidneys to include a production process involving the use of a series of acetone wash steps of the pig kidneys, followed by heat-drying steps, milling and sieving, to result in a pale brown powder of the novel food which is formulated either in enteric coated capsules or as encapsulated enteric coated pellets or enteric coated tablets to reach the active sites of digestion, and the use of ultra-high performance liquid chromatography linked with fluorescent detection as an additional method to the currently authorised one for the determination of the enzymatic activity of diamine oxidase (‘DAO’) contained in the protein extracted from the pig kidneys.
