This study aimed to investigate the effects of postbiotics from Lactiplantibacillus plantarum (PL) and Thymus daenensis Celak essential oil (TDEO) nanoemulsion (EON) on the microbial, chemical, and sensorial characteristics of rainbow trout fillets. PL50 (50% w/v of PL), EON1.5 (1.5% v/v TDEO), EON3 (3% v/v TDEO), and PL50-EON (combined forms of PL50 and EON at two concentrations) were applied as treatments. Total psychrotrophic count (TPC), total mesophilic count (TMC), pH, total volatile base nitrogen (TVB-N), thiobarbituric acid (TBA), and sensorial characteristics of the control and treatment groups were evaluated during nine days of storage at 4 °C. The shelf life of control sample was up to 6 days, while on the same day, PL50-EON3 exhibited significantly lower TPC (2.59 log10 CFU/g), TMC (4.87 log10 CFU/g), and TVB-N value (23.40 mg/100 g). Sensory evaluation showed that sample with PL50-EON3 had higher acceptance than the control. Principal component analysis revealed that EON3 and PL50-EON3 had positive effects on the quality parameters of the fillets. In conclusion, PL50-EON prolonged the shelf life of fillets by more than 3 days based on microbial, chemical, and sensorial threshold limits. These findings demonstrate the potential of PL and TDEO to develop a preservative solution for fish.

Moringa seeds are an excellent dietary source of phytochemicals (i.e., glucosinolates, GSLs; isothiocyanates, ITCs) with health-beneficial effects. Although numerous studies have been conducted on moringa seeds, the effect of germination on the regulation of GSLs remains scarcely explored. The present study investigated the dynamic changes of GSLs in moringa seeds during germination (at 25, 30, and 35 °C for 6 days in the dark) through an untargeted metabolomics approach and compared the antioxidant capacity of ungerminated and germinated moringa seeds. Our results showed that germination significantly increased the total GSL content from 150 (day 0) to 323 μmol/g (35 °C, day 6) on a dry weight (DW) basis, especially glucomoringin (GMG), the unique glucosinolate in moringa seeds, which was significantly upregulated from 61 (day 0) to 149 μmol/g DW (35 °C, day 4). The upregulation of GMG corresponded to the metabolism of tyrosine, which might be the initial precursor for the formation of GMG. In addition, germination enhanced the total ITC content from 85 (day 0) to 239 μmol SE/g DW (35 °C, day 6), indicating that germination may have also increased the activity of myrosinase. Furthermore, germination remarkably increased the total phenolic content (109–507 mg GAE/100 g DW) and antioxidant capacity of moringa seeds. Our findings suggest that moringa sprouts could be promoted as a novel food and/or ingredient rich in GMG.

This research aimed to assess the effects of flaxseed mucilage (Mu) coatings supplemented with postbiotics (P) obtained from Lactobacillus acidophilus LA-5 on various physical, biochemical, and microbial characteristics of strawberry fruits. Strawberry fruits were immersed for 2 min in Mu2.5 (2.5% mucilage in distilled water), Mu5 (5% mucilage in distilled water), P-Mu2.5 (2.5% mucilage in undiluted postbiotics) and P-Mu5 (5% mucilage in undiluted postbiotics) solutions and were stored at 4 °C and 85 RH for 12 days. All coatings were effective in reducing fungal count compared to the uncoated control fruits. Mu5 coating exhibited the highest efficacy, reducing fungal count by 2.85 log10 CFU/g, followed by Mu2.5 (1.47 log10 CFU/g reduction) and P-Mu2.5 groups (0.90 log10 CFU/g reduction). The fruits coated with edible coatings showed significant delays in the change of weight loss, pH, and total soluble solids as compared to the uncoated fruits. The coating containing postbiotics i.e., P-Mu5 also showed a significant increase in the total phenolic contents, total flavonoid content, antioxidant capacity, and total anthocyanin content at the end of storage relative to the uncoated fruits. Thus, Mu and P-Mu coatings may be a useful approach to maintaining the postharvest quality of strawberry fruits during cold storage.

... The coating can be applied to the surface of packaging films, trays, or containers using methods such as spraying, dipping, or brushing. For instance, a solution containing heat-inactivated probiotic cells can be sprayed onto the inner surface of food packaging films to create a protective layer that inhibits the growth of spoilage bacteria and extends the shelf life of packaged foods (Hua et al., 2022;İncili et al., 2021;Sharafi et al., 2024). This coating technique allows for targeted delivery of bioactive compounds to the food surface, enhancing their effectiveness in preventing microbial contamination. ...

... By the co-cultivation of P. freudenreichii and Bifidobacterium animalis subsp. Lactis, the vitamin B 12 content reached up to 8.93 µg/L in soy whey, whereas in the single-culture fermentation of P. freudenreichii, 5.72 µg/L was detected [47]. The fermentation of solubilised wheat bran with P. freudenreichii resulted in the production of 55 µg/L vitamin B12 through co-fermentation with lactic acid bacteria and yeasts [48]. ...

... PPW inoculated with R. oryzae possessed lactate dehydrogenase, pyruvate decarboxylase, and ethanol dehydrogenase, which produced ethanol and lactic acid, although only lactic acid production has been reported previously. Moreover, Alkalbani et al. (2024) used Pichia cecembensis and P. kudriavzevii to prepare fermented date syrup waste (FDSW). FDSW has a significant α-amylase inhibitory effect and antitumor potential as evidenced by significant cytotoxicity against Caco2 and MCF-7 cancer cell lines. ...

... 36 We need focused studies to confirm if camel milk or its constituents could protect against the adverse effects of infant formula and enterally administered pharmaceuticals. 101 The mechanisms by which camel milk could exert its antioxidant effects may involve optimization of signaling pathways involving ABTS (2,2'-azino-bis-3-ethylbenzthiazoline-6-sulphonic acid), DPPH (1,1-diphenyl-2-picrylhydrazyl), and FRAP (ferric-reducing antioxidant power). It also induces antioxidant mediators, such as ACE, glutathione (GSH), superoxide dismutase (SOD), and glutathione peroxidase (GPx). ...
