In this study, we devised a photothermally stable phytochemical dye by leveraging alizarin in conjunction with the metal–organic framework ZIF-8 (AL@ZIF-8). The approach involved grafting alizarin into the microporous structure of ZIF-8 through physical adsorption and hydrogen-bonding interactions. AL@ZIF-8 significantly enhanced the photostability and thermostability of alizarin. The nanoparticles demonstrate substantial color changes in various pH environments, showcasing their potential for meat freshness monitoring. Furthermore, we introduced an intelligent film utilizing poly(vinyl alcohol)-sodium alginate-AL@ZIF-8 (PA-SA-ZA) for detecting beef freshness. The sensor exhibited a superior water contact angle (52.34°) compared to the alizarin indicator. The color stability of the film was significantly enhanced under visible and UV light (ΔE < 5). During beef storage, the film displayed significant color fluctuations correlating with TVB-N (R 2=0.9067), providing precise early warning signals for assessing beef freshness.

“…The desirable and favourable inherent properties for both natural pigments and natural biopolymers such as abundance in nature, easy preparation, non‐toxicity, biodegradability and environmental friendliness have increased the appetite for their application in the food industry. Lately, researchers have focused in developing smart packaging material based on natural pH‐sensitive pigments immobilised in biopolymers for food freshness monitoring in real time (Ezati & Rhim, 2020b; Ran et al ., 2022; Zhang et al ., 2023). This innovation does not only communicate the packaged food's quality status but it also has the potential to reduce food waste and food poisoning incidences.…”

SummaryRecently, the assimilation of pH‐sensitive natural pigments into biopolymers has shown promising prospects for pH‐reactive based smart packaging material. Unlike synthetic pigments, which have potential safety problems due to migration, natural pigments have negligible toxicity levels both to humans and the environment and some even possess nutritional and pharmacological properties. To complement the advantages of natural pigments, natural biopolymers have proven to be ideal candidates for the development of smart packaging because of their biocompatibility, availability, biodegradability, stability, minimum toxicity and good film‐forming capability. Smart packaging gives consumers real‐time signals on the quality of packaged food via food deterioration indicators like pH alteration. This review will consider the recent progress in the development of pH‐responsive smart packaging based on natural pH‐sensitive pigments and natural biopolymers from 2013 to the present. It will further discuss the challenges and opportunities of colorimetric smart packaging.

“…Zhang, Zhang et al. (2023) investigated the exudation of butterfly pea flower anthocyanin from κ‐carrageenan‐based indicator films at pHs 2, 5, 8, and 10 within 70 min. The results showed that the anthocyanin leakage accelerated with the increase in pH, and the exudation rates reached 90% after 60 min at pH 2 and 30 min at pH 10.…”

Naturally sourced pH‐sensitive indicator films are of interest for real‐time monitoring of food freshness through color changes because of their safety. Therefore, natural pigments for indicator films are required. However, pigment stability is affected by environmental factors, which can in turn affect the sensitivity and color stability of the pH‐sensitive indicator film. First, natural pigments (anthocyanin, betalain, curcumin, alizarin, and shikonin) commonly used in pH‐sensitive indicator films are presented. Subsequently, the mechanisms behind the change in pigment color under different pH environments and their applications in monitoring food freshness are also described. Third, influence factors, such as the sources, types, and pH sensitivity of pigments, as well as environmental parameters (light, temperature, humidity, and oxygen) of sensitivity and color stability, are analyzed. Finally, methods for improving the pH‐sensitive indicator film are explored, encapsulation of natural pigments, incorporation of a hydrophobic film‐forming matrix or function material, and protective layer have been shown to enhance the color stability of indicator films, the addition of copigments or mental ions, blending of different natural pigments, and the utilization of electrospinning have been proved to increase the color sensitivity of indicator films. This review could provide theoretical support for the development of naturally sourced pH‐sensitive indicator films with high stability and sensitivity and facilitate the development in the field of monitoring food freshness.
