中文摘要:

      随着人们对食品质量及其品质等级的日益关注, 人们致力于开发有效、可靠、无损的食品新鲜度评价方法。水产品新鲜度指示物通常是由敏感材料和固定载体构建的, 通过敏感材料与水产品新鲜度劣变过程中产生的特定产物发生反应, 并将化学反应结果转换成易于消费者直接观察和判断的信号, 如颜色信号、电信号、荧光信号等。本文综述了水产品新鲜度指示物的常见敏感材料及其应用进展, 重点探讨了新鲜度指示物的制备方法及其优缺点, 包括溶液浇铸法、旋转涂布法、浸渍烘干法、静电纺丝技术、二维印刷法和三维打印技术等。同时从不同角度总结了提升新鲜度指示物性能的策略, 采用添加功能物质、封装技术和化学修饰法等策略能提高指示物的稳定性, 混合染料、金属离子络合和比色阵列等提高指示物灵敏度的有效方法, 最后提出了未来食品新鲜度研究的机遇和挑战, 旨在为食品智能包装新鲜度指示物的发展提供参考。

英文摘要:

      As consumer awareness of food quality and its grading continues to increase, there is a growing focus on developing effective, reliable and non-destructive methods for assessing food freshness. Aquatic product freshness indicators are typically constructed from sensitive materials and fixed carriers. These materials react with specific substances generated during the degradation process of aquatic product freshness, converting the chemical reaction results into signals that are easily observable and interpretable by consumers, such as color changes, electrical signals, or fluorescence signals. This review summarized the common sensitive materials used in aquatic product freshness indicators and their application progress. It particularly explored various preparation methods for these indicators, along with their advantages and limitations, including solution casting, spin coating, impregnation-drying, electrospinning, 2D printing, and 3D printing technologies. Additionally, strategies to enhance the performance of freshness indicators were discussed from multiple perspectives. The use of functional additives, encapsulation techniques, and chemical modifications could improve the stability of the indicators, while methods like dye blending, metal ion complexation, and colorimetric arrays had proven effective in enhancing their sensitivity. Finally, the article outlined the opportunities and challenges for future research in food freshness, aiming to provide insights for the development of intelligent food packaging freshness indicators.
