Despite the technological advances keeping meat fresh for as long as possible, certain aging processes are unavoidable. Adenosine triphosphate is a molecule produced by breathing and responsible for providing energy to cells. When an animal stops breathing, ATP synthesis also stops, and the existing molecules decompose into acid, diminishing first flavor and then safety. Hypoxanthine and xanthine are intermediate steps in this transition. Assessing their prevalence in meat indicates its freshness. In AIP Advances, researchers developed a biosensor using graphene electrodes modified by zinc oxide nanoparticles to measure HXA. The team demonstrated the sensor’s efficacy on pork meat.
