“…Figure 4 displays the Ce 3d spectra of UiO-66, 2:1 UiO-66/ MWCNT, 1:1 UiO-66/MWCNT, and 1:2 UiO-66/MWCNT, where the peaks with binding energies at 885 and 906 eV were attributed to Ce 3d 3/2 and Ce 3d 5/2 , respectively. 35 In contrast to the UiO-66 and UiO-66/MWCNT nanocomposite, the Ce 3d peak intensities were reduced. In addition, the characteristic peaks of the composite were negatively shifted, which was due to the reduced content of metal Ce in composite materials compared to UiO-66.…”

Amine gases and formaldehyde (HCHO) have been used as typical indicators to monitor the quality of marine fish products. However, current detection methods are time-consuming and complicated to preprocess and have limitations such as high technicality requirements. Therefore, developing a sensor capable of simultaneously detecting multiple amine gases and HCHO with high performance in a simple way remains a significant challenge. In this paper, trimethylamine (TMA), dimethylamine (DMA), ammonia gas (NH 3 ), and HCHO were tested by a quartz crystal microbalance (QCM) gas sensor modified with a UiO-66/multiwalled carbon nanotube (MWCNT) nanocomposite. The sensor was operated at room temperature (25 °C) and fixed humidity (35% RH), and the results showed that the limits of detection of the QCM gas sensor for TMA, DMA, NH 3 , and HCHO were 0.32, 0.52, 1.02, and 2.4 μmoL L −1 , respectively. At the same time, our sensor could be reused more than ten times without degradation of sensor signals and showed high stability even after a long storage period of up to 2 months. The adsorption mechanism of the UiO-66/MWCNT nanocomposite-based QCM gas sensor toward the target gases was simulated. Ultimately, salmon meat was examined using the sensor that had been prepared, and the detection outcomes were contrasted with the findings from the Kjeldahl nitrogen determination. The results indicated that refrigerated salmon began emitting target gases on the second day and gradually increased thereafter. By the fifth day, the concentration of the target gases reached the point of complete spoilage. Our platform may be a promising platform for basic research and versatile practical applications in food quality assessments.

“…Similarly to the previous results, the K values of the CK and Shewanella putrefaciens groups increased faster, exceeding 50% on the sixth day simultaneously, indicating that the fish was no longer fresh at this point, and the K value exceeded 70% on the ninth day, making the fish inedible. However, the K values of the Sterility group increased more slowly, and at the end of storage, the K value of the fish was lower than 50%, indicating that microbial growth was the main factor in the loss of fish freshness [26,27]. The K value growth rate of group Pseudomonas fluorescens was lower than that of groups CK and Shewanella putrefaciens, due to the following factors: 1.…”

This study examined the spoilage potential of specific spoilage organisms on the degradation of adenosine triphosphate (ATP)-related compounds in vacuum-packed refrigerated large yellow croaker. The total viable count (TVC), ATP-related compounds and related enzymes of vacuum-packed refrigerated large yellow croaker inoculated with different bacteria (Pseudomonas fluorescens and Shewanella putrefaciens) were characterized using the spread plate method, high-performance liquid chromatography and assay kits, respectively. Results indicated that the TVC for both control and Shewanella putrefaciens groups reached spoilage levels at days 9 and 15, respectively. The changes of adenosine triphosphate (ATP), adenosine diphosphate (ADP), adenosine monophosphate (AMP) and adenosine deaminase activity across all groups showed no significant difference attributable to microbial growth. The results suggested that ATP to inosine monophosphate (IMP) degradation primarily occurs via fish’s endogenous enzymes, with minimal microbial involvement. On day 12, the IMP content in fillets inoculated with Pseudomonas fluorescens (0.93 μmol/g) was half higher than in those inoculated with Shewanella putrefaciens (0.57 μmol/g). Both spoilage organisms facilitated IMP degradation, with Shewanella putrefaciens making a more substantial contribution. Analysis of K values and correlation coefficients revealed that Shewanella putrefaciens was the primary factor in the freshness loss of refrigerated vacuum-packed large yellow croaker. These findings offer a reference for understanding quality changes in refrigerated large yellow croaker, especially regarding umami degradation at the microbial level.

“…Aquatic food is rich in high-quality proteins, lipids, unsaturated fatty acids, and vitamins, and is a general consumer favorite. Aquatic food is a major perishable food because some specific spoilage organisms (SSO) play a pivotal role in fish putrefaction, resulting in food quality problems and great financial losses. , However, it has been reported that the main cause of some SSOs included Shewanella spp., Pseudomonas spp., Acinetobacter spp., and Micrococcus spp. − In particular, Shewanella putrefaciens is a key leading cause of food spoilage and known as an SSO from bigeye tuna, pacific white shrimp, and Sciaenops ocellatus during transportation and storage.…”

Shewanella putrefaciens is a typical spoiler that is commonly found in seafood and has high spoilage potential. However, the spoilage mechanism against Shewanella putrefaciens at the gene and metabolism levels has not been well elucidated. This work determined the spoilage targets on Shewanella putrefaciens XY07 from spoiled bigeye tuna by genome sequencing, metabolomics, and Fourier transform infrared (FTIR) analysis. Shewanella putrefaciens XY07 contained some genes on spoilage regulating of cys genes, his genes, spe genes and rpoS gene involved in sulfur metabolism, histidine metabolism, arginine and proline degradation, and biofilm formation at the genome level, respectively. Some spoilage genes like speC, cysM, trxB genes were identified. In addition, ABC transporters, arginine and proline metabolism; beta-alanine metabolism; glycine, serine, and threonine metabolism; histidine metabolism; sulfur metabolism; and lipid metabolism were identified as important pathways related to aquatic food during spoilage, which indicated the functions of amino acid degradation in S. putrefaciens XY 07 by metabolomics analysis. The metabolites of l-ornithine, 5-aminopentanoate, and 4-aminobutyraldehyde could be further metabolized to spermidine and spermine, producing a spoilage odor, and were involved in arginine and proline metabolism serving as key spoilage regulating metabolisms. Therefore, Shewanella putrefaciens XY07 was applied to genomics, metabolomics analysis, and FTIR to provide comprehensive insight into the investigation of spoilage targets.
