Kinetic modelling of acrylamide formation during the frying of potato chips
نویسندگان
چکیده
The effect of potato tuber composition, frying time and temperature on acrylamide formation in chips was investigated a mathematical model the kinetics is provided. Moisture-temperature–time profiles were obtained for slices during to enable determination ‘effective’ reaction by identifying critical moisture content (6% dwb) commence using dehydration curves calculate subsequent finished product content. chemical kinetic conformed following rate equation over one hundred-fold range concentrations: d[acryl]dt=k1glucoseasn+k6[fructose][asn][TAA] where [TAA] represents total amino acid concentration. timescale process meant that reactions all their initial phase. Kinetic parameters confirm fructose-dependent (caramelization) contributes twice as much glucose (Maillard reaction).

Low-acrylamide French fries and potato chips
SUMMARY Acrylamide is produced in starchy foods that are baked, roasted or fried at high temperatures. Concerns about the potential health issues associated with the dietary intake of this reactive compound led us to reduce the accumulation of asparagine, one of its main precursors, in the tubers of potato (Solanum tuberosum). This metabolic change was accomplished by silencing two asparagine s...

Quantitation of acrylamide in potato chips by hplc-ms
A method of reversed-phase liquid chromatography coupled with mass spectrometry (LC-MS) in combination with a stable isotope dilution assay was used to quantify acrylamide in potato chips. This in-house procedure was evaluated for precision, and accuracy. LC-MS revealed as a cost-effective and robust technique for acrylamide analysis in potato chips. Acrylamide formation was studied during deep...
متن کاملMeasurement of Acrylamide in Potato Chips by Portable FTIR Analyzers
Acrylamide is a compound that forms in french fries, potato chips, cereal, bread and coffee when they are fried, roasted or baked. The formation is dependent on cooking conditions, for example, high temperature over-cooking of fried chips results in very high levels of acrylamide. The substance, which forms from the reaction of sugar and amino acids in food, is reported to be a likely human car...
