The EFSA Panel on Food Contact Materials assessed the safety of 2,2'-oxydiethylamine, which is intended to be used at up to 14% w/w as a monomer along with adipic acid and caprolactam to make polyamide thin films intended for single use, in contact with all types of food under all conditions of time and temperature. Specific migration of 2,2'-oxydiethylamine was tested from a polyamide film in water and was below the limit of quantification (LOQ) of 0.015 mg/kg.

By formal addition of P to the latter, an unprecedented tetraphosphenium ion forms which likewise is capable of P transfer and qualifies as Lewis superacid based on its computed fluoride ion affinity. As a solid, this species is stable and conveniently storable, featuring a remarkably long P-P bond (2.

- Fecal microbiota transplantation (FMT) was evaluated for its ability to induce remission in Crohn's disease (CD) in a double-blind study, marking the first investigation of its kind.
- The study involved 21 patients receiving FMT and 13 receiving a placebo, and was terminated early due to futility, showing no significant difference in remission rates between groups at week 8.
- While FMT did not improve clinical outcomes, both groups reported improvements in health-related quality of life; future research may explore alternative strategies to boost treatment efficacy.
Article Synopsis
- The EFSA Panel on Food Contact Materials evaluated the safety of two wax additives used in various plastics for food packaging, confirming their safety for consumer use under specified conditions.
- The substances demonstrated low migration levels into food, indicating minimal transfer of additives, especially in aqueous environments.
- Genotoxicity tests showed no safety concerns, leading to the conclusion that these additives are safe for food contact, excluding fatty foods, when used at recommended concentrations.
Paper and board are widely used as food contact materials. For such sensitive applications, consumer safety regarding the transfer of chemical components and contaminants to the food needs to be established. Such safety assessments are becoming increasingly challenging not only due to intentionally added substances but also non-intentionally added substances.
