Leveraging amaranthus leaf extract (ALE) as an indicator, polyvinyl alcohol (P), and citric acid (C) as film fabricating materials, an innovative time-temperature indicator (TTI) for beef freshness tracking film, known as PC-ALE was successfully created. The films were characterized in terms of their kinetic modeling, molecular properties, morphological characterization, and physiochemical properties. Arrhenius model was made by utilizing the colorimetric values of TTI films collected from -10 to 35 °C. The correlation coefficient and activation energy of the fitting model were 0.9467, 0.9399, 0.6886, and 123, 57, 95 kJ.mol
