“…Zaytsev et al . developed an optical method to detect catecholamines and metabolites based on the interaction of the compounds with silver nanoprisms leading to LSPR peak wavelength shifts (Zaytsev et al., 2020). Although the method is simple and fast, it may not be specific since many other compounds present in biological fluids may interact with unmodified nanoprisms.…”

“…However, electrochemical methods were primarily identified for catecholamine metabolites. One interesting example is the multiplexed detection of catecholamines and their metabolites (El Khamlichi et al, 2018;Zaytsev et al, 2020). Khamlichi et al used a carbon/chitosan paste electrode for multiplex normetanephrine and dopamine electrochemical detection in five-fold diluted human urine with LODs of 18.3 and 7.6 ppb, respectively (El Khamlichi et al, 2018).…”

Meat quality can be affected by stress, exhaustion, feed composition, and other physical and environmental conditions. These stressors can alter the pH in postmortem muscle, leading to high pH and low‐quality dark cutting (DC) beef, resulting in considerable economic loss. Moreover, the dark cutting prediction may equally provide a measure for animal welfare since it is directly related to animal stress. There are two needs to advance on‐site detection of dark cutters: (1) a clear indication that biomarker (signature compounds) levels in cattle correlate with stress and DC outcome; and (2) measuring these biomarkers rapidly and accurately on‐farm or the abattoir, depending on the objectives. This critical review assesses which small molecules and proteins have been identified as potential biomarkers of stress and dark cutting in cattle. We discuss the potential of promising small molecule biomarkers, including catecholamine/cortisol metabolites, lactate, succinate, inosine, glucose, and β‐hydroxybutyrate, and we identify a clear research gap for proteomic biomarker discovery in live cattle. We also explore the potential of chemical‐sensing and biosensing technologies, including direct electrochemical detection improved through nanotechnology (e.g., carbon and gold nanostructures), surface‐enhanced Raman spectroscopy in combination with chemometrics, and commercial hand‐held devices for small molecule detection. No current strategy exists to rapidly detect predictive meat quality biomarkers due to the need to further validate biomarkers and the fact that different biosensor types are needed to optimally detect different molecules. Nonetheless, several biomarker/biosensor combinations reported herein show excellent potential to enable the measurement of DC potential in live cattle.
