Abstract

Carotenoids are fat-soluble natural pigments with potent antioxidant and antibacterial properties, and their colors are sensitive to environmental pH changes (halochromic properties). Currently, natural carotenoids are utilized in the preparation of active packaging films, drawing significant attention in the field of food engineering for their potential application in smart packaging films. The use of carotenoids-based active films has shown promise in prolonging shelf life, but their application as pH-sensitive pigments in smart packaging for monitoring food freshness remains less established due to the several drawbacks (i.e., visual changes and others) discussed in this work. This critical review primarily summarizes the most used smart packaging materials, the halochromic properties of carotenoids and other pigments, and the applications of carotenoids-based films/bioplastics as pH-sensitive smart packaging for monitoring food freshness. Finally, we present to the readers our expert overview of the advantages and disadvantages associated with these natural pigments in the packaging sector.

用于智能食品包装的类胡萝卜素薄膜的卤色特性

类胡萝卜素是一种脂溶性天然色素，具有很强的抗氧化和抗菌性能，其颜色对环境 pH 值的变化非常敏感（半色性）。目前，天然类胡萝卜素被用于制备活性包装膜，其在智能包装膜中的潜在应用引起了食品工程领域的极大关注。基于类胡萝卜素的活性薄膜在延长保质期方面已显示出良好的前景，但由于本研究中讨论的几个缺点（如视觉变化等），类胡萝卜素作为 pH 值敏感颜料在智能包装中监测食品新鲜度的应用仍不太成熟。本评论主要总结了最常用的智能包装材料、类胡萝卜素和其他颜料的卤色特性，以及类胡萝卜素薄膜/生物塑料作为 pH 值敏感智能包装在监测食品新鲜度方面的应用。最后，我们将以专家的视角向读者介绍这些天然色素在包装领域的优缺点。

期刊介绍： Food packaging is crucial for preserving food integrity throughout the distribution chain. It safeguards against contamination by physical, chemical, and biological agents, ensuring the safety and quality of processed foods. The evolution of novel food packaging, including modified atmosphere and active packaging, has extended shelf life, enhancing convenience for consumers. Shelf life, the duration a perishable item remains suitable for sale, use, or consumption, is intricately linked with food packaging, emphasizing its role in maintaining product quality and safety.
