N-Hydroxymethylacrylamide, N-methylacrylamide, and N,N-diethylacrylamide produce peripheral neuropathy in rats. Seven other compounds related to acrylamide do not produce neuropathy. Rats given one of the three neurotoxic compounds are more susceptible to acrylamide. A regime for testing acrylamide analogues for neuro-toxicity is suggested. DDT, phenobarbitone, or high dietary concentrations of...
Acrylamide is potential carcinogenic compound that possesses neurotoxicity activity. In this study, the levels of acrylamide in 123 selected food samples from China was evaluated using a LC/MS/MS method. One hundred and fifteen (115) out of 123 samples showed positive levels of acrylamide in the range of 0.41 to 4,126.26 µg/kg. Generally, the highest acrylamide levels were found in fried produc...
Acrylamide is a probable human carcinogen that is found in many roasted and baked foods. This paper describes two sensitive and reliable LC-(ESI)MS/MS methods for the analysis of (1) acrylamide and (2) common acrylamide precursors (i.e., glucose, fructose, asparagine, and glutamine) in raw and roasted almonds. These methods were used to evaluate the impact of roasting temperatures (between 129 ...
BACKGROUND Acrylamide has shown developmental and reproductive toxicity in animals, as well as neurotoxic effects in humans with occupational exposures. Because it is widespread in food and can pass through the human placenta, concerns have been raised about potential developmental effects of dietary exposures in humans. OBJECTIVES We assessed associations of prenatal exposure to dietary acry...
BACKGROUND Acrylamide as a possible carcinogen is known to form in heated carbohydrate-rich food such as potato chips. In this study, the effect of three potato varieties (Agria, Sante and Savalan) and two blanching conditions (75 °C for 9 min and 83 °C for 2.5 min) on the concentration of precursors and acrylamide reduction in potato chips was investigated. RESULTS Results revealed that pota...
BACKGROUND The rodent carcinogen acrylamide was discovered in 2002 in commonly consumed foods. Epidemiologic studies have observed positive associations between acrylamide intake and endometrial, ovarian, and breast cancer risks, which suggest that acrylamide may have sex-hormonal effects. METHODS We cross-sectionally investigated the relationship between acrylamide intake and plasma levels o...
OBJECTIVE To assess the current status of the acrylamide in the Chinese food supply, the dietary acrylamide exposure in the Chinese population and to estimate the public health risks of the current consumption. METHODS The acrylamide content in the total diet study (TDS) food samples was analyzed using an LC-MS/MS method. Based on the analytical results, the dietary exposure calculations were...
BACKGROUND Numerous studies have demonstrated acrylamide to be both neurotoxic and carcinogenic. At present it is widely recognised that acrylamide is mainly formed through the Maillard reaction from free asparagine and reducing sugars. The major sources of dietary acrylamide are potato products, processed cereals and coffee. OBJECTIVE To optimise and validate an analytical method for determi...
Acrylamide or 2-propenamide is a chemical compound, with chemical formula CH2=CH–CO–NH2, that can be produced at high levels in high-carbohydrate heattreated foods. The risks of acrylamide to health and its toxic properties (neurotoxicity, genotoxicity, carcinogenicity and reproductive toxicity) were demonstrated by the Scientific Committee on Toxicity, Ecotoxicity and the Environment in 2001. ...
the best ph for getting millard reaction started and acrylamide formation ranges 7 to 8. ph below the range slows the reaction speed down and the resultant acrylamide formation delayed. this research assess how acetic acid in 0.05, 0.15, 0.25% concentrations together with sourdough may promote acidity in bread dough and how they can cause a reduction of acrylamide content in sangak bread [an ir...
