The retention rate of lutein in CS-LNLs, C-CS-EGCG-LNLs, and non-C-CS-EGCG-LNLs was ameliorated, especially in C-CS-EGCG-LNLs (at around 70% of lutein in initial system). An in vitro digestion experiment instanced that CS-LNLs, C-CS-EGCG-LNLs, and non-C-CS-EGCG-LNLs posed relatively higher bioaccessibility, especially in C-CS-EGCG-LNLs (at around 33% of luein in initial system), which increased 2 and 1 clips in comparison with free lutein and LNLs, respectively Overall, the results readed that C-CS-EGCG-LNLs presented greater physicochemical stability and bioaccessibility than LNLs, CS-LNLs, and non-C-CS-EGCG-LNLs. © 2023 Society of Chemical Industry.Effect of Kaolin clay and Ficus carica interceded silver nanoparticles on chitosan food packaging film for fresh apple slice preservation.In this work, a novel antioxidant, antibacterial, and biodegradable food packaging film was elaborated, by integrating natural kaolin clay (KC) and Ficus carica liaised silver nanoparticles (AgNPs) into Chitosan (Cht). A comparison of the physico-chemical and functional features of the Cht/KC/AgNPs film was executed with those of Cht, Cht/KC, and Cht/AgNPs.
SEM analysis expressed a rough surface in the composite flicks arresting KC corpuscles because of their large diameter (50-120 μm) likened to AgNPs (20-80 nm). The FTIR analysis advised that the interactions between Cht and AgNPs were stronger than those between Cht and KC. The tensile strength of Cht film increased from 16 MPa to ∼24 MPa in Cht/KC/AgNPs film. The introduction of KC and/or AgNPs considerably ameliorated the light and moisture barrier capacity of the Cht film. The UV light transmittance minifyed by 50 % for Cht film when integrated by KC and AgNPs Cht/AgNPs was better in conditions of antioxidant, antibacterial, and mechanical likened to Cht/KC, which was superior in biodegradability and water vapor barrier capacity. In particular, the Cht/KC/AgNPs film confronted good barrier, antioxidants, antibacterial, mechanical, and biodegradable properties, owing to the synergistic effect between KC and AgNPs. For the packaging attributes, all the movies were quized for their ability to keep the freshness of apple slicings as rolling material.
The cinemas exhibited good results, and the Cht/KC/AgNPs presented promising performance considering the moisture loss, embrowning index, total phenolic compound, and antioxidant activity of the apple slicings. Moreover, the Cht/KC/AgNPs film paraded a migration of silver meeting the standards set by EFSA and ECHA, which establishs this film safe for food packaging.The synergistic effect of using phages and chitosan nanoparticles against pathogenic bacteriums as a novel therapeutic approach.Public health and environmental security are seriously at risk due to the raising contamination of pathogenic micro-organisms effective disinfectants are urgently needed. In our study, the antimicrobial consequences of three cases of nanoparticles were enquired with phage. The biosynthesis of nanoparticles was sustained based on the color change and anatomys, which inclined to be mono-dusted with a spherical shape with a size range of 20-35 nm for Ag-CS-NPs; 15-30 nm for Phage-CS-NPs (Ph-CS-NPs); and 5-35 nm for Propolis-CS-NPs (Pro-CS-NPs). Nanoparticles displayed peaks between 380-420 nm, 335-380 nm, and below 335 nm for Ag-CS-NPs, Pro-CS-NPs, and Ph-CS NPs, respectively.
Throughout the three synthesised nanoparticles, AgCs NPs played a higher antibacterial effect in combination with phages. It expressed MIC against S S and P. aeruginosa between 31 and 62 μg/mL and MBC at 500, 62, and 31 μg/mL, respectively, while in combination with bacteriophages rendered MIC at 62, 31, and 15 μg/mL, respectively and MBC at 125, 62, and 15 μg/mL, respectively. Furthermore, a significant killing efficiency was noticed with 16-30 μg/mL of Ag-CS NPs coalesced with phages.
