“…This difference is due to structural differences in bacterial cell walls. Gram-negative bacteria have an outer lipopolysaccharide membrane, whereas Gram-positive bacteria have a peptidoglycan structure with a single layer ([ 50 , 51 ]). Furthermore, when the proportion of SCSE exceeded that of chitosan, a higher percentage of colony reduction was observed for both types of bacteria.…”

Banana (Musa acuminate) has been popular among consumers worldwide due to its rich nutrients and minerals. However, bananas are highly susceptible to the physical and biological factors that lead to postharvest loss during transportation and storage. In this work, novel sodium alginate (SA) films incorporated with silver nitroprusside nanoparticles (AgNNPs) were prepared to extend the shelf life of bananas through antibacterial and antioxidant coating. The results exhibited that AgNNPs were cubical and that their size was <500 nm, with metal composition being Ag and Fe. Additionally, the incorporation of AgNNPs in the SA film was seen in FE-SEM and zeta analysis, with an average size of about 365.6 nm. Furthermore, the functional and crystalline properties of AgNNPs were assessed through FTIR and XRD. Transmittance testing of the SA-AgNNPs films confirmed they have good UV barrier properties. SA-AgNNPs films exhibited excellent high antibacterial activity against foodborne pathogens including L. monocytogenes, S. enterica, and E. coli at the concentration of 500 µg/mL. Moreover, during the storage of bananas, SA-AgNNPs nanocomposite coatings act as a barrier to microbial contamination and slow down the ripening of bananas. As a result, compared with SA-coated and uncoated bananas, SA-AgNNPs-coated bananas exhibited the lowest weight loss and lowest total bacterial colonies, thus greatly extending their shelf life. Particularly when coated with SA-AgNNPs films, total bacterial colonies (TBC) in the banana peel and pulp were as low as 1.13 × 103 and 51 CUF/g on the ninth day of storage, respectively. Our work offers an efficient strategy to improve the quality of bananas during the postharvest period, with extensive applications in fruit preservation and food packing.

“…İki film arasındaki tek fark tip 2 filme boş ZİF-8 nanokristallerinin eklenmiş olmasıdır. Daha önce yapılan çalışmalarda boş ZİF-8 nanokristallerinin mevcut çalışmada olduğu gibi E. coli ve S. aureus patojenlerine karşı antimikrobiyal bir etkisinin olmadığı gösterilmiştir (Fu vd.,2022). Tip 3 filmler içerisinde istatistiksel olarak önemli farklılık K-ZİF-8 konsantrasyonu 5XMÖK ve üstüne çıktığında gözlemlenmiştir.…”

“…Bu çalışmada polimer yapısına dahil edilen kurkumin ihtiva eden ZİF-8 vasıtasıyla pH ve ışığa duyarlı gıda endüstrisi için antibakteriyel ambalaj malzemesi geliştirilmiştir. Bir diğer çalışmada ise ZİF-8 nanokristalleri bakır oksit için taşıyıcı olarak kullanılarak polilaktik asit, polivinil asit ve kitosan ile çok katmanlı filmler elde edilmiştir (Fu vd., 2022). Bu filmler domatesin raf ömrünü uzatmak için koruyucu ambalaj olarak kullanılmış ve antimikrobiyal etkinlikleri çalışmada gösterilmiştir.…”

Active packaging aims to reduce food waste by extending food shelf life. Packaging materials developed from biodegradable, sustainable and renewable resources are required to reduce environmental pollution and conserve natural resources. Therefore, curcumin, a natural extract with antioxidant and antimicrobial properties, was encapsulated into zeolitic imidazole framework-8 nanocrystals (K-ZIF-8) in this study. Chitin nanocomposites, support materials of the designed active package, were extracted from the cultivated mushroom. Bioactive properties of the films improved as the amount of K-ZIF-8 increased. Addition of K-ZIF-8 did not have a significant effect on mechanical, barrier, optical, thermal and morphological properties of chitin films. Antimicrobial test revealed that chitin-based nanocomposite films were effective against E.coli, but not against S.aureus. The highest antimicrobial effect, total phenolic content and antioxidant activity was obtained in the film containing 10XMIC equivalent of K-ZIF-8 concentration. However, film durability tests indicated that these films are not suitable for long-term storage.
