“…The advantage of the electrochemical approach is a relatively short measuring time including sample preparation (Wang 2001). Amounts of acrylamide were measured by square-wave voltammetry in potato chips (Zargar et al 2009). Recently, a new approach to electrochemical determination of AA was published (Veselá and Šucman 2013).…”

Acrylamide is considered to be an endogenous contaminant of food and feedstuff. Attention is paid to the acrylamide content in human nutrition products; however, there is lack of data about its concentrations in feedstuff. The aim of this study was to use a newly developed adsorptive stripping voltammetry procedure for determination of acrylamide concentrations in five and three different kinds of dog and cat dry feedstuff, respectively. The applied analytical procedure consists of a solvent extraction in ultrasound bath, followed by voltammetric measurement at the hanging mercury drop electrode in ammonia buffer. The accuracy of the method was verified by use of standard reference materials. The range of acrylamide concentration found in samples of dry dog and cat feedstuff ranged from 106 to 358 μg/kg, and from 66 to 269 μg/kg, respectively. The precision of analyses expressed in form of the relative standard deviations ranged between 0.6-1.7%. The voltammetric procedure appears to be a reliable, sensitive, rapid and low-cost analytical technique for the determination of acrylamide in food and feedstuff. The concentrations of acrylamide found in feedstuff were relatively moderate but it is undoubtedly necessary to monitor its concentrations in future.

“…Another detection principle is based on the catalysis of the reduction of AA with the assistance of electrolytes, such as LiCl and cobalt(Ⅱ) ions (Niaz et al, 2008;Zargar, Sahraie, & Khoshnam, 2009). Specifically, AA was reduced with the catalysis of the Co ion accompanied by electron transfer and finally changes in current for signal readout (Zargar et al, 2009).…”

Veselá H., Šucman E. (2013): Determination of acrylamide in food using adsorption stripping voltammetry. Czech J. Food Sci., 31: 401-406.A new electroanalytical method for the determination of acrylamide in food has been developed. It was found that a complex of acrylamide and Ni 2+ is suitable for the electrochemical determination of acrylamide. Ammonia buffer of pH = 9.5 was found to provide convenient conditions for the determination. Optimal concentration of Ni 2+ was 500 µmol/l. The sample preparation procedure was optimised. The best results were found for an ethanol/water mixture (1:2) and pH = 1.4. The samples were extracted in an ultrasound bath, and after centrifugation 0.2 ml of the extract was taken for the measurement. Voltammetric measurements were done using the hanging mercury drop electrode. The peak height was a function of acrylamide concentration and deposition time. The accuracy of the method was verified by the use of standard reference materials.
