Members of the genus are frequently associated with meat spoilage. The ability for low numbers of spores of certain species to germinate in cold-stored vacuum-packed meat can result in blown pack spoilage. However, little is known about the germination process of these clostridia, despite this characteristic being important for their ability to cause spoilage. This study sought to determine the genomic conditions for germination of 37 representative strains from seven species (, , , , , and ) by comparison with previously characterized germination genes from , and . All the genomes analysed contained at least one operon. Seven different operon configuration types were identified across genomes from , and . Differences arose between the genomes and those belonging to / in the number and type of genes coding for cortex lytic enzymes, suggesting the germination pathway of is different. However, the core components of the germination pathway were conserved in all the genomes analysed, suggesting that these species undergo the same major steps as for germination to occur.

It is an important task to construct intelligent packaging for meat freshness monitoring with good color stability and indication function. Herein, cobalt-based metal-organic framework nanomaterials (Co-MOF, ZIF-67) with antimicrobial and ammonia-sensitive properties were successfully synthesized and added into gelatin/agar (GA) matrix to develop highly stable intelligent films (GA/ZIF67). The incorporation of ZIF-67 nanoparticles enhanced the hydrophobicity (water contact angle >90°) and UV-blocking properties (close to 0.

Multifunctional pH-responsive films were fabricated via layer-by-layer deposition of gelatin, chitosan, and carboxymethyl cellulose (CMC), incorporating selenium nanoparticles (SeNPs) and beetroot extract (BTE), to monitor and preserve beef freshness. SeNPs were synthesized and characterized via various techniques. BTE exhibited promising functional properties, and films demonstrated a significant color transition from red to yellow across pH 2-14.

It is required to have a more straightforward and easier way to check the quality of food to ensure the safety of the public heaths. The decomposition of meat protein results in ammonia and biogenic amines (BAs). Here, we have designed and synthesized three luminescent-based probe molecules, which originated from 2-(2-hydroxyphenyl) benzothiazole (HBT) derivatives and showed the excited state-induced proton transfer (ESIPT) phenomenon.

The aim of this study was to investigate the differences of quality indexes, bacterial community and volatile organic compounds (VOCs) of industrial-scale tiger skin chicken feet (TSCF) under air packaging (AP) and vacuum packaging (VP). The results showed that the pH, total volatile basic nitrogen, total number of bacterial colony, and sensory scores in VP group changed less than those in AP group during the storage period. Different packaging conditions also had significant effects on bacterial community at the genus levels.

The aim of this study is to evaluate the effect of some microalgae species adding with different forms on minced beef meat shelf life during cryogenic storage for 13 days. Chlorella vulgaris and Arthrospira platensis are chosen because of their safety and high nutritional value. Microalgae nanoparticles with their different forms have been prepared by using emulsification solvent evaporation method.
