Intelligent food packaging system exhibits enhanced communication function by providing dynamic product information to various stakeholders (e.g., consumers, retailers, distributors) in the supply chain. One example of intelligent packaging involves the use of colorimetric indicators, which when subjected to external stimuli (e.g., moisture, gas/vapor, electromagnetic radiation, temperature), display discernable color changes that can be correlated with real-time changes in product quality. This type of interactive packaging system allows continuous monitoring of product freshness during transportation, distribution, storage, and marketing phases. This review summarizes the colorimetric indicator technologies for intelligent packaging systems, emphasizing on the types of indicator dyes, preparation methods, applications in different food products, and future considerations. Both food and nonfood indicator materials integrated into various carriers (e.g., paper-based substrates, polymer films, electrospun fibers, and nanoparticles) with material properties optimized for specific applications are discussed, targeting perishable products, such as fresh meat and fishery products. Colorimetric indicators can supplement the traditional “Best Before” date label by providing real-time product quality information to the consumers and retailers, thereby not only ensuring product safety, but also promising in reducing food waste. Successful scale-up of these intelligent packaging technologies to the industrial level must consider issues related to regulatory approval, consumer acceptance, cost-effectiveness, and product compatibility. 相似文献

Increased environmental and health concerns over the use of plastic packaging or fluorine-containing coatings, in combination with increased market demand for products with a longer shelf life, make bio-based materials one of the most important research candidates for alternative paper packaging materials for oil resistance. These bio-based materials have excellent oxygen and oil barriers, which are critical for food packaging. Moreover, they are biodegradable, naturally renewable, and safe. In this artical, two main groups of bio-based oil repellents for paper food packaging, including polysaccharide-based biopolymers and protein-based biopolymers, are enumerated, and the advantages and weaknesses of bio-based oil repellents are discussed, and effective solutions are proposed. Finally, research status and prospects on the development of bio-based oil-resistant coatings for the food packaging industry are presented. 相似文献

食品包装在保持食品质量和延长货架寿命方面起着关键作用。然而,传统的塑料包装存在环境污染和可持续性问题,因此,寻找可持续、环保的替代材料已成为当前研究的热点。与单层生物基膜相比,多层生物基薄膜表现出更好的机械性能、阻隔性等,由于多层包装材料在各层之间有更为复杂的内部结构和更大的层间空间使其更合适活性物质的引入,因此近年来引起了广泛的关注和研究。该文综述了多层生物基薄膜的构建方法及其在包装食品领域中的应用。讨论了生物基包装材料的分类,对多层生物基薄膜的制备方法包括层层自组装技术(LbL)、电流体力学方法、共挤压方法和溶剂浇铸法的制备过程及其优缺点进行介绍,通过近年来对多层生物基包装在食品领域的研究进展进行综合分析和总结,提出了生物基多层薄膜未来的研究方向和发展趋势。 相似文献

Recently, 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. 相似文献
