Abstract A remarkable one‐third of global food production is wasted, resulting in significant economic damage and escalating insecurity. To address this sustainability challenge, freshness identification packaging using intelligent materials has gained traction. This work introduces a chitosan‐ graft ‐gelatin (CS‐g‐GEL) hydrogel, incorporating pH‐responsive dye, bromothymol blue (BTB), as colorimetric indicator to monitor the spoilage chicken breasts. The successful formulation hydrogels verified FTIR, AFM, SEM, TGA, 1 HNMR characterization techniques. At pH 5 7.4, swelling capacity hydrogel 790% 470%, respectively. rise colony‐forming units (CFU) from 5.5 on day 1–7.4 log CFU g −1 7 indicate microbial activity, carbon dioxide due deteriorating decreases package. Additionally, CO 2 concentrations 3.2 1–22.1 (% v/v) 7, while O levels 23.8 near 0.5 same period. developed demonstrated serve smart visual offers new dimension use toward challenge.
