Dry-Heat Cooking of Meats as a Source of Airborne N-Nitrosodimethylamine (NDMA)

Atmosphere, 2019
This study aimed to investigate the airborne release of N-nitrosodimethylamine (NDMA) as a result of the dry-heat cooking of some meats using charcoal grilling and pan-broiling methods. Three types of meat (beef sirloin, pork belly, and duck) were chosen

Millimeter/Nano‐Structured Metal Monolithic Catalysts: A Privileged Opportunity for Sustainable Water Purification

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Cross‐scale assembly of metal (sub) nanoparticles and/or single atoms into millimeter/nanostructured metal monolithic catalysts (Min‐SMCs) is highly appealing for sustainable water cleanup, due to energy‐efficient catalyst recyclability, high infrastructure compatibility, and low metal‐releasing risks.

Inactivation Strategies of Clostridium perfringens in Foods: Current Challenges and Emerging Interventions

Food Frontiers, Volume 7, Issue 3, May 2026.
Clostridium perfringens forms heat‐resistant spores that complicate food safety. Physical methods (thermal processing, HPP, vacuum cooling, ozone treatments) and chemical interventions (natural antimicrobials, phosphates, nitrate/nitrite, organic acids) reduce vegetative cells and spores, though spore resistance remains a major challenge in food and ...

Determination and Confirmation of N-Nitrosodimethylamine in Beer

Journal of AOAC INTERNATIONAL, 1981
Abstract A qualitative method has been developed for the confirmation of N-nitrosodimethylamine (NDMA) in beer by capillary gas chromatography-mass spectrometry (GC/MS) from full mass scans after quantitation, using a gas chromatograph interfaced to a thermal energy analyzer (GC/TEA). The GC/MS method has a lower limit of confirmation of

Losartan API and Nitrosamines Impurities—Stability Profile Investigation Using HPLC, LC‐MS, and In Silico Assessment

Journal of Separation Science, Volume 49, Issue 5, May 2026.
ABSTRACT Nitrosamines are potent genotoxic impurities with well reported mutagenic and carcinogenic effects. Their presence has been detected in several pharmaceutical products among them losartan, an angiotensin II receptor blocker. Considering the risks already reported for these impurities, the present study aimed to investigate the influence of ...
