“…Thus, they enjoy numerous potential applications, such as in prophylaxis, therapy and agricultural production [14]. The most suitable polysaccharides in developing nanoparticles are: starch, cellulose, alginates, pectins, xanthan gum, cyclodextrins, chitosan [15], heparin [16], furcellaran [17] and hyaluronic acid [18][19][20].…”

Polymer nanocomposites containing nanometals became a subject of interest due to their bactericidal properties. Different polysaccharides have been used as matrices for nanosilver and nanogold synthesis. In this study, we present a novel, environmentally friendly method for the preparation of sodium alginate/nanosilver/graphene oxide (GOX) and sodium alginate/nanogold/graphene oxide GOX nanocomposites and their characteristics. The formation of approximately 10–20 nm ball-shaped Ag and Au nanoparticles was confirmed by UV–vis spectroscopy, scanning electron microscopy (SEM) and Fourier transform infrared (FTIR) spectra. The incorporation of GOX sheets within the ALG matrix improved the thermal stability of the nanocomposites film, which was measured using the differential scanning calorimetry (DSC). We also estimated the molecular weights of polysaccharide chains of the matrix with the size exclusion chromatography coupled with multiangle laser light scattering and refractometric detectors (HPSEC-MALLS-RI). The composites were more prone to enzymatic hydrolysis. The strongest bacteriostatic activity was observed for the sample containing nanosilver.

“…When the color of the solution turned slightly brownish, a plasticizer-glycerol (0.5% v/w based on the solution)-was added. The prepared solution was poured onto a petri dish (diameter 14 cm) and dried in a hood for 48 h. FUR + AgNPs film was characterized in detail in the previous work [26]. The AgNPs were observed by back-scattered electron imaging.…”

“…Therefore, the smell of both cheese varieties wrapped in the active film was less appreciated by panelists than that of control. The change in consistency was a consequence of the decrease in water content as a result of a much higher WVTR of the FUR + AgNPs [26] than LLDPE [40] film. Amjadi et al [42] also determined a reduction in the hedonic scores of smell and overall acceptance during the storage of white cheese wrapped in films containing zinc oxide nanoparticles.…”

There is a serious need to develop and test new biodegradable packaging which could at least partially replace petroleum-based materials. Therefore, the objective of this work was to examine the influence of the recently developed furcellaran nanocomposite film with silver nanoparticles (obtained by an in situ method) on the quality properties of two cheese varieties: a rennet-curd (gouda) and an acid-curd (quark) cheese. The water content, physicochemical properties, microbiological and organoleptic quality of cheese, and migration of silver nanoparticles were examined. Both the number of Lactococcus and total bacteria count did not differ during storage of gouda regardless of the packaging applied. The number of Lactococcus decreased in analogous quark samples. The use of the film slowed down and inhibited the growth of yeast in gouda and quark, respectively. An inhibitory effect of this film on mold count was also observed; however, only regarding gouda. The level of silver migration was found to be lower in quark than in gouda. The film improved the microbiological quality of cheeses during storage. Consequently, it is worth continuing research for the improvement of this film in order to enable its use in everyday life.

“…The application of carbon nanotubes as nanofillers in gelatin films has also been successfully demonstrated (Rai et al 2019 ). The biofilms are found to have improved tensile strength, mechanical, thermal and antimicrobial properties (Jamróz et al 2020 ; Zubair and Ullah 2020 ). Thus, nanomaterials have emerged as an integral part while addressing nanotechnology in food packaging.…”
