Abstract: World hunger is getting worse, while one-third of foods produced around the globe is wasted and never consumed. It is vital in reducing food waste to promote the sustainability of agri-food systems. Intelligent packaging embedded with freshness indicators can monitor food freshness in a real-time manner and be deployed for cutting food waste produced due to predetermined expiration date and informing consumers of food safety. Biodegradable halochromic films have been increasingly utilized as freshness indicators because of their low environmental impact. In this review, recent advances in biodegradable halochromic indicators for intelligent packaging are reported. The pH-responsive behaviors of natural pigments, the development of biodegradable solid supports for freshness indicators, the colorimetric response of freshness indicators to food products and simulated models, and future challenges in this field are discussed. Particularly, novel technologies coupled with halochromic indictors are highlighted, including sensor arrays, nanocomposites, smartphone-assisted detection, and ink-free printing.

Abstract: AbstractThe growing demand for natural, safe, and clean-label food preservatives has intensified interest in the antimicrobial potential of spices and herbs. This review critically examines the bioactive components and mode of action of certain culinary spices and herbs, specifically garlic, turmeric, clove, cinnamon, thyme, oregano, black pepper, coriander, and fennel, as well as their use in food preservation systems. These plant-derived compounds exhibit broad-spectrum antimicrobial activity through diverse mechanisms including disruption of microbial membranes, inhibition of enzymatic systems and modulation of oxidative stress. These compounds have shown effectiveness against key foodborne pathogens such as Escherichia coli, Listeria monocytogenes, Salmonella spp., Staphylococcus aureus, and various spoilage fungi. Recent improvements in nanoencapsulation, edible films, and active packaging have increased their application in current food production. This review emphasizes the potential of spices and herbs to serve as effective, environmentally friendly alternatives to synthetic preservatives, thereby contributing to the creation of safer and more sustainable food systems.
