Abstract
A humidity-tolerant on-package freshness label was prepared by entrapping black carrot anthocyanins in a WAPI–SA/PVA aerogel reinforced with silica-stabilized LDH. The LDH–silica phase strengthened the porous matrix and helped control water uptake, thereby contributed to moisture resistance and supported retention of the indicator’s colorimetric function in humid environments. The label responded to trimethylamine (TMA) over 10–1000 ppb with sharp, measurable color shifts; ΔE and RGB values extracted from images gave a linear analytical response with high sensitivity. In shrimp trials, color evolution progressed with spoilage and remained consistent with total volatile basic nitrogen (TVB-N) trends, enabling practical freshness-stage classification. The moisture sorption behavior of the aerogel was investigated across different temperatures (25, 35, 45, and 55 °C at 75% relative humidity), alongside a dedicated refrigerated storage condition (4 °C/35% RH) as a cold-chain reference. Kinetic evaluation at 75% RH demonstrated that moisture uptake followed a first-order kinetic profile with temperature-dependent linear moisture-uptake rates. Arrhenius modeling within the 25–55 °C range yielded an apparent activation energy of 21.70 kJ⋅mol −1 (R 2 = 0.99), confirming that the indicator possesses robust structural stability and low susceptibility to ambient humidity fluctuations under standard cold-storage condition. These results support the WAPI–SA/PVA–LDH–silica aerogel as a robust amine-responsive label for on-package shrimp freshness indication.
