Summary: Metal-cation induced self-assembly of a pyrene-peptide conjugate can form hydrogels with different morphology and mechanical properties depending on the type of metal ions present. The presence of metal ions also opens up new applications, such as using Cu2+ metallogels for amine sensing and meat freshness monitoring, and Zn2+ metallogels for cationic dye adsorption and separation.

Summary: Food spoilage leads to waste and diseases. A miniature sensor based on poly(styrene-co-maleic anhydride) was developed for on-demand spoilage analysis via mobile phones. The sensor was embedded in packaged chicken and beef to monitor spoilage. This low-cost, miniature wireless sensor can help consumers and suppliers detect spoilage of protein-rich foods and prevent food waste and food-borne diseases.

Summary: This study screened three strains from different regions of Inner Mongolia that have the ability to degrade biogenic amines (BAs) in meat products. These strains can degrade various BAs, especially tryptamine and phenethylamine. They can be used as starter cultures in meat products due to their good fermentation capacity and strong ability to reduce BAs.

Summary: Sensing materials based on ionically conductive metal-organic frameworks (IC-MOFs) with metal ions as charge carriers were developed for detecting cadaverine vapor, an important chemical marker of food spoilage. Among different types of IC-MOFs, IC-CuTHPP-MOFs showed the greatest response to cadaverine, with a detection limit of 4.9 nL. These sensors demonstrated high sensitivity, selectivity, and stability, with a fast and real-time response to rotting meat.

Summary: This study demonstrates the efficient utilization of anthocyanins extracted from Malva Sylvestris in smart food packaging. The incorporation of anthocyanins into polylactic acid has led to the development of a novel intelligent freshness indicator capable of differentiating between fresh, medium fresh, and spoiled proteinous foods. The indicator's ability to accurately respond to the spoilage of various foods is crucial for commercialization in the industry.

Summary: The study focuses on the amount of heterocyclic aromatic amines in meat products during heat treatment, identifying potential mutagens. Results show that meat products sold in supermarkets contain significantly higher levels of mutagens compared to those grilled in laboratory conditions. Future research will focus on improving analysis methods and developing purification techniques to reduce human consumption of mutagens.

Summary: Biogenic amines are organic compounds commonly found in food, plants, animals, and microorganisms. They are formed through the decarboxylation of amino acids. While crucial for cell viability and metabolic processes, excessive biogenic amines can be toxic and even accelerate carcinogenesis.

Summary: The aim of this study was to investigate the biofilm-producing capacity of Lentilactobacillus parabuchneri strains. The results showed that the biofilm matrices of these strains were mainly composed of proteins and they easily adhered to beech wood. This study provides important insights into the biofilm-forming capacity of histamine-producing L. parabuchneri strains and how to prevent their formation for improving food safety.

Summary: The study developed and characterized two novel bioactive coatings deposited on TiAlV and AISI 316LVM substrates using 3D printing and electrospinning techniques. The coatings were loaded with the antibiotic clindamycin and their properties such as contact angle, swelling rate, biodegradability, and biocompatibility were investigated through various tests. The released concentration of clindamycin in PBS and its effects on osteoblast cells were also evaluated.
