The good performance conditions for determination of EU priority PAHs in coffee samples were established to evaluate the effects of roasting degree on the PAHs in coffee beans and the brewing methods on the PAHs transfer from coffee beans to their brews. The consumption risk of the PAHs in coffee products was also assessed. The PAHs levels of the roasted coffee beans were in the order: 923.65 ng/g (dark roast) > 132.20 ng/g (medium roast) > 69.28 ng/g (light roast). Compared with general brewing with the drip bag (PAHs content, 0.30–0.62 ng/mL in coffee brews), the coffee machine brewing (set at 4 …

Drug substances are at risk of contamination with N-nitrosamines (NAs), well-known carcinogenic agents, during synthesis processes and/or long-term storage. Therefore, in this study, we developed an efficient data-based screening approach to systemically assess marketed products and investigated its scalability for benefiting both regulatory agencies and pharmaceutical industries. A substructure-based screening method employing DataWarrior, an open-source software, was established to evaluate the risks of NA impurities in drug substances. Eight NA substructures containing susceptible amino sources for N-nitrosation have been identified as screening targets: dimethylamine (DMA), diethylamine, isopropylethylamine, diisopropylamine, N-methyl-2-pyrrolidone, dibutylamine, methylphenylamine, and tetrazoles. Our method detected 192 drug …


A Review Of Human Factors And Food Safety In Ireland, Ciara Walsh, Maria Chiara Leva Jan 2019

A Review Of Human Factors And Food Safety In Ireland, Ciara Walsh, Maria Chiara Leva

Articles

Increased product shelf-life and globalisation have led to longer and vastly more complicated food chains; potentially presenting greater opportunity for contamination and microbial growth to occur. Modern food safety management systems risk assess hazards (based on current scientific data) and strive to control these, often extensive and convoluted, food production/supply chains through appropriate good hygiene practices (GHP) and HACCP. Contamination of food as a result of human error can undermine even the most carefully prepared and executed HACCP system – culminating in foodborne infection, outbreaks, reputable damage, and erosion of consumer trust. This paper provides a review on the effect …
