N -Nitrosamines (NAs) are now known to be a widely acting group of animal carcinogens (3) and are found, usually at trace levels, in many diverse places in the environment, such as: nitrite- cured meats, polluted air, tobacco smoke, cutting oils, hydraulic fluids, cosmetics, herbicides, ...
common NAs.Published or derived TD50s were developed for NAs that have both robust and limited but sufficient data.SARs and available toxicology data were used to derive AIs based on pre-established conservative thresholds.This process was intended to advance methodology for deriving AIs for NAs.DOI...
Effect of inoculating Lactobacillus pentosus R3 on N -nitrosamines and bacterial communities in dry fermented sausagesLactobacillus pentosusN -nitrosamineBacterial communityDry fermented sausageWe investigated the effects of Lactobacillus pentosus inoculation on N -nitrosamines (NAs) contents and bacterial ...
Fig. 1. The levels of NAs found in six different products after and before heat treatment, either by frying on a pan (Bacon 1 and 2) or backing in an oven preheated to 250 °C (Ham 1 and 2 and pepperoni and chorizo). Each bar represents three samples of heat treated or not heat...
In general, an increase in the level of NAs was observed after the storage period. The proposed method may therefore be a useful tool for food safety control once it allows assessing the profile and the dietary intake of NAs in food over time....
Volatile N-nitrosamines (NAs) in rubber nipples for baby bottles were determined by gas chromatography (GC) using a thermal energy analyzer (TEA). Rubber nipple samples were cut into pieces, and NAs were extracted with dichloromethane under ultrasonic irradiation. The samples were cleaned by liquid...
