Determination of acrylamide in dry feedstuff for dogs and cats

Abstract

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.

Acrylamide in dog food

“…In a previous study, although the number of samples was small (i.e., four samples), the level of acrylamide detected in dry food was 106-358 ng/g (Veselá and Šucman, 2013). In the present study, acrylamide concentrations ranged 14.7-68.6 ng/g in dry food, which was lower than that in the previous report.…”

Getting angry with endocrine-disrupting chemicals

“…Insofar as endocrine-disrupting chemicals are increasingly entering and acting upon our bodies, then, I argue, they also play a part in the fundamental processes that shape our hormonal makeup, and thus also our emotional well-being and subjective experience. The Endocrine Disruption Tracker Tool (EDTT) is a speculative instrument that I have created (Veselá, 2022) which foregrounds disrupted emotions as an index of endocrine disruption. I have developed the EDTT as a tool for a collective investigative practice in which I can examine, together with other research participants, what we can learn about endocrine disruption if we consider how our emotions are affected.…”

“…Gender Studies scholar Celia Roberts (2007) has coined the term "messengers of sex" as a means of critically analyzing how hormones act to produce sexed bodies and behaviors. Her analysis of how the biological and the social come together in the concept of the hormone has inspired and informed a growing body of research, which has extended her insights in order to address the biosocial character of endocrine-related toxicity (Ah-King & Hayward, 2014;Bailey, 2010;Birke, 2000;Chen, 2012;Davis, 2015;2022;Di Chiro, 2010;Haraway, 2012;Hayward, 2014;Langston, 2010;Lee, 2020;O'Laughlin, 2016;Oppermann, 2016;Pollock, 2016;Robyn & Mykitiuk, 2018;Scott, 2009;Shotwell, 2016). Building upon the theoretical findings and queer ecological sensibilities of these researchers, this essay attends to the signals (chemical and cultural) that are transmitted and communicated within the material-discursive networks of endocrine disruptors.…”
