Özet
<p>Intelligent packaging systems are innovative applications developed to monitor food quality</p><p>and enhance safety during transportation and storage. Among these systems, pH-based</p><p>halochromic indicators offer the ability to visually and in real time monitor the freshness status</p><p>of food. This study aims to examine the structure, working mechanisms, production methods,</p><p>and application areas of halochromic systems based on a review of the literature. Scientific</p><p>articles and industry reports in the literature have been systematically evaluated, and both</p><p>natural and synthetic halochromic dyes (such as anthocyanins and bromocresol green) have</p><p>been discussed in terms of functionality, safety, and color stability. The effectiveness of</p><p>halochromic systems integrated into packaging films through methods such as electrospinning,</p><p>casting, immobilization with nanoparticles, and sol-gel method in determining food freshness</p><p>has been discussed. It has been observed that current commercial applications are limited; while</p><p>natural pigments offer potential environmentally friendly alternatives, their stability issues</p><p>remain a challenge to be improved. In conclusion, halochromic indicators are a significant tool</p><p>in enhancing food safety, and there is a need for advanced technologies to develop more stable</p><p>and reliable systems.</p>
