The formation of acrylamide in crystalline model systems based on asparagine and reducing sugars was investigated under low-moisture reaction conditions. The acrylamide amounts were correlated with physical changes occurring during the reaction. Molecular mobility of the precursors turned out to be a critical parameter in solid systems, which is linked to the melting behavior and the release of...
OBJECTIVE To explore the harmful effects of acrylamide on the structure of testis in albino rats, in an attempt to clarify its potential risks on human health. METHODS The present study was carried out in the Department of Anatomy, Faculty of Medicine, King Abdulaziz University, Jeddah, Kingdom of Saudi Arabia from December 2010 to December 2011. Forty-eight adult male albino rats (250-300 g)...
Free amino acids and reducing sugars participate in the Maillard reaction during high-temperature cooking and processing. This results not only in the formation of colour, aroma and flavour compounds, but also undesirable contaminants, including acrylamide, which forms when the amino acid that participates in the reaction is asparagine. In this study, tubers of 13 varieties of potato (Solanum t...
In 2002, public health concerns were raised by Swedish studies showing that relatively high levels of acrylamide were formed during the frying, roasting, or baking of a variety of foods, including potatoes, cereal products and coffee at temperatures above 120 degrees C. Acrylamide possesses a range of hazardous properties, the key effects being carcinogenicity, genotoxicity, neurotoxicity and r...
In this issue of the Journal, Besaratinia and Pfeifer (1) add to the toxicologic evidence that acrylamide has the ability to induce genetic damage in mammalian cells. Acrylamide or probably glycidamide, its genotoxic metabolite, has a relatively low mutagenic potency and is likely to have a relatively small impact on the overall cancer risk of an individual. However, because rather high concent...
Potato is the raw food material that has been used the most in frying operations due to the high demand of consumers all over the world. Detection of high concentrations of acrylamide in heated starch rich foodstuffs, such as potato, by the Swedish National Food Administration in April 2002 attained public concern because this product is a suspected human carcinogen. Maillard reaction is sugges...
This paper investigated the efficiency of antioxidant of bamboo leaves (AOB) and extract of green tea (EGT) on the reduction of acrylamide in fried bread sticks and summarized the optimal levels of two additives. Seven experimental groups including a control group were organized for both of additives. Fried bread sticks were made via traditional processing technology. The flour was mixed with d...
Acrylamide exposure has been related to an increased incidence of oral and thyroid tumors in animal studies. In 1986, 120,852 persons (aged 55-69 years) were included in the Netherlands Cohort Study. Dietary acrylamide intake was assessed with a food frequency questionnaire and was based on chemical analysis of all relevant Dutch foods. Hazard ratios were adjusted for smoking and other confound...
A sensitive analytical method for the analysis of acrylamide and other electrophilic agents in water has been developed. The amino acid L-valine served as a nucleophilic trapping agent. The method was applied to the analysis of acrylamide in 0.2-1 mL samples of drinking water or Millipore-filtered water, brewed coffee, or water extracts of snuff. The reaction product, N-(2-carbamoylethyl)valine...
