“…This result might be accounted for by CM acting as a plasticizer in GN films and was identical to the results of Luo et al [19], who discovered that the EAB in GN films significantly increased with adding CM. Parallel findings by Orozco-Parra et al [36] and other researchers [37,38] also revealed that various carbohydrates, such as polysaccharides, glucose, and fructooligosaccharides, showed a plasticization in the films, reducing TS while enhancing EAB. Moreover, when L. lactis was added to the composite films, there was a slight (p > 0.05) rise in EAB.…”

In this work, a gelatin/chia mucilage (GN/CM) composite coating material doped with Lactococcus lactis (LS) was developed for strawberry preservation applications. The results of the scanning electron microscope and Fourier transform infrared spectroscopy stated that the enhanced molecular interaction between the CM and GN matrix strengthened the density and compactness of the GN film. Antifungal results indicated that the addition of LS significantly (p < 0.05) improved the ability of the GN coating to inhibit the growth of Botrytis cinerea (inhibition percentage = 62.0 ± 4.6%). Adding CM significantly (p < 0.05) decreased the water vapour permeability and oxygen permeability of the GN coating by 32.7 ± 4.0% and 15.76 ± 1.89%, respectively. In addition, the incorporated CM also significantly (p < 0.05) improved the LS viability and elongation at break of the film by 13.11 ± 2.05% and 42.58 ± 1.21%, respectively. The GN/CM/LS composite coating material also exhibited an excellent washability. The results of this study indicated that the developed GN/CM/LS coating could be used as a novel active material for strawberry preservation.

Antibacterial hand sanitizers could play a prominent role in slowing down the spread and infection of hand bacterial pathogens; luteolin (LUT) is potentially useful as an antibacterial component. Therefore, this study elucidated the antibacterial mechanism of LUT against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) and developed an antibacterial hand sanitizer. The results showed that LUT had excellent antibacterial activity against both E. coli (minimum inhibitory concentration (MIC)= 312.5 μg/mL, minimal bactericidal concentration (MBC) = 625 μg/mL), and S. aureus (MIC = 312.5 μg/mL, MBC = 625 μg/mL). Furthermore, LUT induced cell dysfunction in E. coli and S. aureus, changed membrane permeability, and promoted the leakage of cellular contents. Confocal laser scanning microscopy (CLSM) and scanning electron microscopy (SEM) analysis showed that LUT treatment affected cell structure and disrupted cell membrane integrity. The Fourier transform infrared analysis (FTIR) also confirmed that the LUT acted on the cell membranes of both E. coli and S. aureus. Overall, the application of LUT in hand sanitizer had better inhibition effects. Therefore, this study could provide insight into expanding the application of LUT in the hand sanitizer markets.

“…7A-C and S3. † 32 The results showed that, compared with C-Film, the brightness (L*) of PPF-1∼5 lms decreased with the decrease of PCs and the increase of Phy, the redness/greenness (a*) and yellowness/blueness (b*) values also showed a similar trend. Aer adding PCs, the color of PPF-1 lm changed from light color (C-Film) to reddish brown, the composite lms of PPF-2, PPF-3 and PPF-4 gradually tended to yellow-green color, and PPF-5 lm containing only Phy was blue (p < 0.05).…”

“…The color properties of bioactive films were recognized as important indexes of packaging materials included appearance, utilization and consumer acceptance, and the influence of different PCs and Phy incorporation ratios on color parameter of film was shown in Fig. 7A–C and S3 † 32 . The results showed that, compared with C-Film, the brightness ( L *) of PPF-1∼5 films decreased with the decrease of PCs and the increase of Phy, the redness/greenness ( a *) and yellowness/blueness ( b *) values also showed a similar trend.…”
