ANNEX In Table 2 (Specifications) of the Annex to Implementing Regulation (EU) 2017/2470, the entry for ‘Protein extract from pig kidneys’ is replaced by the following: Authorised Novel Food Specification ‘ Protein extract from pig kidneys Description/Definition: 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. Basic Product: Specification: pig kidney protein extract with natural content of Diamine oxidase (DAO): Physical condition: liquid Colour: brownish Appearance: slightly turbid solution pH value: 6,4–6,8 Enzymatic activity: > 2 677 kHDU DAO/ml (DAO REA (DAO Radioextractionassay)) Microbiological criteria: Brachyspira spp.: negative (Real Time PCR) Listeria monocytogenes: negative (Real Time PCR) Staphylococcus aureus: < 100 CFU/g Influenza A: negative (Reverse Transcription Real Time PCR) Escherichia coli: < 10 CFU/g Total aerobic microbiological count: < 10 5 CFU/g Yeasts/moulds count: < 10 5 CFU/g Salmonella: Absence/10g Bile salt resistant enterobacteriaceae: < 10 4 CFU/g Final product: Specification pig kidney protein extract with natural content of DAO (E.C. 1.4.3.22) in an enteric coated formulation: Physical condition: solid Colour: yellow grey Appearance: micropellets or tablets Enzymatic activity: 110-220 kHDU DAO/g pellet or g tablet (DAO REA (DAO Radio Extraction Assay)) Acid stability 15 min 0,1M HCl followed by 60 min Borat pH = 9,0: > 68 kHDU DAO/g pellet or g tablet (DAO REA (DAO Radio Extraction Assay)) Humidity: < 10 % Microbiological criteria: Staphylococcus aureus : < 100 CFU/g Escherichia coli : < 10 CFU/g Total aerobic microbiological count: < 10 4 CFU/g Total combined yeasts/moulds count: < 10 3 CFU/g Salmonella : Absence/10g Bile salt resistant enterobacteriaceae: < 10 2 CFU/g PCR: Polymerase Chain Reaction; HDU (Histamine Degrading Units); Description/Definition: The protein extract is obtained from homogenised pig kidneys through a series of steps involving a number of acetone washes to defat and dehydrate the homogenized pig kidneys, followed by draining, drying, milling, and sieving to produce a powder containing essentially proteins with a 7-9 % (on average) content of the enzyme diamine oxidase (enzyme nomenclature E.C. 1.4.3.22). The pig kidney extract powder is formulated either in enteric coated capsules or as encapsulated enteric coated pellets or enteric coated tablets to reach the active sites of digestion. Basic Product: Specification: pig kidney protein extract with natural content of Diamine oxidase (DAO): Physical condition: powder Colour: pale brown Enzymatic activity: ≥ 0,10 mU/mg (UHPLC-FLD (Ultra High Performance Liquid Chromatography linked with Fluorescent Detection)). Humidity: < 10 % Residual Solvents: Acetone: < 5 000 mg/kg Microbiological criteria: Staphylococcus aureus : < 100 CFU/g Escherichia coli : < 10 CFU/g Total aerobic microbiological count: < 10 4 CFU/g Total combined yeasts/moulds count: < 10 3 CFU/g Salmonella : Absence/10g Bile salt resistant enterobacteriaceae: < 10 2 CFU/g Listeria monocytogenes : absence in 25 g Final product: Specification pig kidney protein extract with natural content of DAO (E.C. 1.4.3.22) in an enteric coated formulation: Physical condition: solid Colour: pale brown Appearance: micropellets, capsules, or tablets Enzymatic activity (micropellets, capsules or tablets): 2,29 – 4,6 mU/g pellet or g tablet or g capsule (UHPLC-FLD (Ultra High Performance Liquid Chromatography linked with Fluorescent Detection)). Acid stability 15 min 0,1M HCl followed by 60 min Borat pH = 9,0: > 1,4 mU DAO/g pellet or g tablet or g capsule (UHPLC-FLD (Ultra High Performance Liquid Chromatography linked with Fluorescent Detection)) Humidity: < 10 % Microbiological criteria: Staphylococcus aureus : < 100 CFU/g Escherichia coli : < 10 CFU/g Total aerobic microbiological count: < 10 4 CFU/g Total combined yeasts/moulds count: < 10 3 CFU/g Salmonella : Absence/10g Bile salt resistant enterobacteriaceae: < 10 2 CFU/g Listeria monocytogenes : absence in 25 g mU: milliUnit (expressed in mU/mg) measures nanomols (nmol) of histamine degraded by the DAO per minute using Ultra High Performance Liquid Chromatography linked with Fluorescent Detection (UHPLC-FLD) (O. Comas-Basté et al. Analytical and Bioanalytical Chemistry 411:7595-7602 (2019)). 1 mU corresponds to 48 000 HDU of the DAO Radio Extraction Assay (REA) method.’
