Abstract:
Meat discoloration is one of the challenges facing the food industry, which affects both quality and shelf life. In this report, we present our groundbreaking discovery of electrochemically probing specific redox peaks associated with meat discoloration and successfully monitor its delay when controlled biochemically with added antioxidants. We have validated the redox features by spectrophotometry measurements of the relative levels of oxymyoglobin, which gives meat its cherry red color, and metmyoglobin, which causes the meat to turn brown in relation to discoloration. The insights from this research open up new avenues for the development of innovative electroanalytical tools for studying meat color and quality. These new tools could potentially minimize nutritious beef waste, lessen the environmental burden associated with waste disposal, and reduce CO2 emissions linked to discoloration issues.

Effects of EDTA on End-Point Detection Methods
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a...
