Following a request from the European Commission, EFSA developed an updated scientific guidance to assist applicants in preparation of applications for food enzymes. This describes data be included authorisation enzymes, as well extension use existing authorisations, accordance with Regulation (EC) No 1331/2008 and its implementing rules. Information provided relates source, production characteristics enzyme, toxicological data, allergenicity dietary exposure estimation. Source, enzyme are...
The EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP Panel) was asked by the European Commission to update its 2005 risk assessments of di-butylphthalate (DBP), butyl-benzyl-phthalate (BBP), bis(2-ethylhexyl)phthalate (DEHP), di-isononylphthalate (DINP) di-isodecylphthalate (DIDP), which are authorised for use in plastic food contact material (FCM). Dietary exposure estimates (mean high (P95)) were obtained combining literature occurrence data with consumption from...

Food enzymes are used for technical purposes in the production of food ingredients or foods-as-consumed. In European Union, safety a enzyme is evaluated by EFSA on basis dossier provided an applicant. Dietary exposure integral part risk assessment enzymes. To develop models specific to each manufacturing process which used, different input data required then tandem with conversion factors. This allows use levels be related consumption collected dietary surveys. For process, identified list...
Technical data for exposure assessment of food enzymes Dietary is part the overall enzymes. In order to develop process-based models, a number different input are required in tandem with technical conversion factors. This allows combination use levels consumption data, which typically reported as consumed. The expressed total organic solids/kg raw materials. For each process, EFSA identified list groups and collated To ensure uniform application FoodEx categories factors enzyme dossiers,...
The Cd and Zn accumulation phytoextraction potential of seven willow clones was investigated in a pot experiment for two vegetation periods. Heavily polluted Fluvisol-Litavka, moderately contaminated Cambisol-Pribram, unpolluted control Chernozem-Suchdol were used. Significant differences found between the clones. transferred from roots to aboveground tissues all tested confirmed higher leaves than twigs. amounts removed by highest most soil (up 83% 71% total removal). Therefore harvest is...
The aim of this study was to evaluate metals (Cd, Cu, Pb and Zn) sorption behavior after biochar application into a metal-contaminated soil. Additionally, two different types originated from the same organic material (contaminated uncontaminated) at rates (1% 2% w/w) were evaluated as novelty experiment. Batch sorption/desorption experiments established compare originating single- multi-element solutions. Zinc one main contaminants in studied soil easily desorbed presence lesser extent by...
The effectiveness of heavy metal uptake from contaminated nutrient solution by four aquatic macrophytes (Pistia stratiotes L., Salvinia auriculata AubL, minima Baker, and Azolla filiculoides Lam) was estimated in this study. influence cadmium (3.5 mg L(-1) 10.5 L(-1)) lead (25 125 on the stress symptoms observed through determination chlorophyll content transpiration rate over 14 days experiment. results present study showed extreme reductions Cd Pb concentrations during first 4 days....
Choline is an important nutrient for humans. intake of the European population was assessed considering Food Safety Authority Comprehensive Consumption Database and United States Department Agriculture Nutrient Database. Average choline ranges were 151-210 mg/d among toddlers (1 to ≤3 years old), 177-304 other children (3 ≤10 244-373 adolescents (10 ≤18 291-468 adults (18 ≤65 284-450 elderly people (65 ≤75 old) 269-444 very (≥75 old). The intakes higher males compared with females, mainly...
Brominated flame retardants – polybrominated diphenyl ethers (PBDEs), biphenyls (PBBs), hexabromocyclododecane (HBCD) and others have been measured in 11 pooled breast milk samples from 109 first-time mothers Ireland. Additionally, the study has levels of dibenzo-p-dioxins furans (PBDD/Fs), mixed halogenated dioxins (PXCC/Fs) (PXBs), polychlorinated naphthalenes (PCNs) perfluoroalkylated substances (PFAS) these samples. The mean sum 19 PBDEs including BDE-209 was 4.85 ng g−1 fat, which is...
Noccaea caerulescens (NC) and Arabidopsis halleri (AH) were studied to compare cadmiunm (Cd) accumulation resistance. After 30, 60 90 days of plant cultivation in Cd contaminated soil (Cd1 = Cd2 Cd3 mg Cd/kg soil) amino acids determined plants. The comparison between both species showed that stress resulted different changes levels playing a significant role adaptation stress. Our analyses indicated higher accumulations the roots NC compared AH. Contrasting responses plants contamination...
To characterize the phytoextraction efficiency of two clones willow trees (Salix x smithiana Willd., Salix rubens) and poplar (Populus nigra maximowiczii, Populus Wolterson) were planted in contaminated soil (0.4–2.0 mg Cd.kg−1, 78–313 Zn.kg−1, 21.3–118 Cu.kg−1). Field experiment was carried out Czech Republic. The study investigated their ability to accumulate heavy metals (Cd, Zn, Cu) harvestable plant parts. poplars produced higher amount biomass than willows. Both accumulated Cd, Zn Cu...
