Article Abstract
The colorimetric food freshness indicator (CFFI) is a promising technology in intelligent food packaging, offering the capability for real-time monitoring of food freshness through colorimetric changes. This technology holds significant promise in mitigating food waste and enhancing transparency across the supply chain. This paper provides a comprehensive review of the classification system for the CFFI, encompassing colorimetric films and sensor arrays. It explores their applications across key perishable food categories, including meats, seafoods, fruits, and vegetables. Furthermore, this paper offers an in-depth analysis of three critical challenges currently hindering technological advancement: safety concerns, stability issues, and limitations in sensitivity and selectivity. In addressing these challenges, this paper proposes forward-looking solutions and outlines potential research directions aimed at overcoming these bottlenecks, thereby fostering substantial progress in the development of this field.

In this study, aloe emodin and β-d-glucose pentaacetate were added into potato starch/polyvinyl alcohol for the construction of colorimetric/fluorescent dual-pass intelligent response labels. Inspired by the lotus leaf structure, retained the advantages of the label itself and solved the hydrophilic problem of the label, and further developed a multi-functional dual-channel smart label with hydrophobicity and self-adhesion. The water contact angle of the prepared T-AEB label was 120.

Fish gelatin (FG) is a biopolymer with favorable biocompatibility, mechanical strength, and water retention, making it ideal for films, hydrogels, and bio-based applications. This study aimed to comparatively investigate the FG based intelligent films and hydrogels for monitoring shrimp freshness. Intelligent films and hydrogels were prepared using FG as a macromolecular matrix, incorporating ferulic acid (FA)-crosslinked anthocyanin (ACN) as an indicator, and enhanced with polysaccharides (κ-carrageenan (κC), xanthan glucomannan (XG), and konjac glucomannan (KGM)).

Given rising consumer demands for meat safety and quality assurance, developing an intuitive, cost-effective, and user-friendly sensor platform for real-time monitoring of perishable meat freshness is important. Herein, this study developed an innovative chitosan/agarose/blueberry anthocyanin (CS/AG/BA) hydrogel label system for visual real-time freshness tracking of perishable proteins through smartphone-assisted colorimetric analysis. Through systematic optimization of CS/AG compositional ratios (3:7-7:3) and pH conditions (2.

Primary agricultural products are closely related to our daily lives, as they serve not only as raw materials for food processing but also as products directly purchased by consumers. These products face the issue of freshness decline and spoilage during both production and consumption. Freshness degradation induces sensory deterioration and nutritional loss and promotes harmful substance accumulation, causing gastrointestinal issues or even endangering life.
