Nisin and curcumin loaded (NCL) nanomats having 172 nm mean diameter were successfully fabricated. The effect of NCL nanomats in terms of limitation of Total Mesophilic Aerobic (TMAB) and Lactic acid bacteria (LAB) in fish fillets was tested during the analysis period. On the 4th day, while TMAB load of C was 6.61 log CFU g−1, that of the sample coated with NCL nanomats was found to be 3.28 log CFU g−1. TMAB load of control samples reached above 6 log CFU g−1 on the 4th day of cold storage, TMAB load of fish samples coated with nanomats reached the same level up to the 12th day. The shelf life of coated fillets was extended to 12 day. 3–4 logarithmic decrease was obtained in LAB count by NCL nanomats during the analysis period. On the 4th storage day, the hardness value of C sample decreased 21% compared to NCL samples. All sensory attributes of C samples were acceptable by the 4th day of the storage; while sensory attributes of NCL samples were acceptable by the 10th day of storage. The study revealed that nisin and curcumin loaded nanomats could be effectively used to improve the quality of fish fillets.

Nanoencapsulation of probiotic bacteria (L. rhamnosus) into poly(vinyl alcohol) & sodium alginate-based nanofibers (VSPBe) and also the production of poly(vinyl alcohol) & sodium alginate-based nanofibers (VS) were successfully obtained. VSPBe and VS nanofibers were used to limit the Total Mesophilic Aerobic Bacteria (TMABc), Psychrophilic Bacteria (TPBc) and also Yeast and Mold count (TYMc) growth in the fish fillet. Dispersion stability (ζ potential −6.29 mV and −7.74 mV, for VS and VSPBe, respectively), thermal decomposition (a reduction in mass of VS and VSPBe at temperatures 50 °C, corresponding to <5% and >5%, respectively) and morphological properties of nanofibers (diameters between 60 nm and 580 nm) were revealed by characterization analysis. Microbiological tests demonstrated that VS and VSPBe were effectively delayed the TMABc and TPBc growth in fish fillets up to 38%. However, the antimicrobial effects of nanofibers were not pronounced for TYM growth in the fish fillet. The viability of probiotic bacteria could be provided after electrospinning process and the use of L. rhamnosus-loaded nanofibers for delaying microbial growth in the fish fillets could be evaluated as a natural/novel technique.
