“…The first peak was in the temperature range of 30-120 °C, which was consistent with HMSS. The second peak emerged in the temperature range of 120-400 °C, which was due to the decomposition of APTES [40]. This phenomenon proved that HMSS was successfully amino functionalized.…”

In recent years, silica nanomaterials have been widely studied as carriers in the field of antibacterial activity in food. Therefore, it is a promising but challenging proposition to construct responsive antibacterial materials with food safety and controllable release capabilities using silica nanomaterials. In this paper, a pH-responsive self-gated antibacterial material is reported, which uses mesoporous silica nanomaterials as a carrier and achieves self-gating of the antibacterial agent through pH-sensitive imine bonds. This is the first study in the field of food antibacterial materials to achieve self-gating through the chemical bond of the antibacterial material itself. The prepared antibacterial material can effectively sense changes in pH values caused by the growth of foodborne pathogens and choose whether to release antibacterial substances and at what rate. The development of this antibacterial material does not introduce other components, ensuring food safety. In addition, carrying mesoporous silica nanomaterials can also effectively enhance the inhibitory ability of the active substance.

“…The existence of the deformation band of C–H (1401 cm –1 ) and ether bond (1027 cm –1 ) can be obtained . All the films showed a similar FT-IR pattern, but CS-based films showed a slight decrease in peak intensity than pure CS film due to the addition of Fe-MoO x and curcumin, which indicated that the hydrogen bonding was the main interaction between filler and CS film . No obvious peaks associated with Fe-MoO x were measured in the XRD patterns of the films, indicating the low relative content of Fe-MoO x in films.…”

The XRD patterns of all films also showed no significant difference (SI, Figure S6), which demonstrated that the filling of Fe-MoO x and curcumin did not affect the crystal structure of CS, verifying the good compatibility of CS with filler.…”

Antimicrobial packing showed great potential in extending the shelf life of food. However, developing a new biocomposite film with an intelligent and efficient antimicrobial performance is still desirable. Herein, a Fe-MoO x encapsulated with curcumin (Cur) filled chitosan-based composite film (CCF films) was prepared by solvent casting method. The total color differences of the CCF films were less than 30%, and satisfactory surface color, transparency, hydrophobicity, and thermal stability were also obtained. Besides, the UV-light/water/oxygen barrier capability and mechanical properties were enhanced with the incorporation of Cur@Fe-MoO x . Moreover, CCF films showed photothermal performance and thermal-controlled curcumin release ability, which endowed the CCF 0.15 film with excellent antibacterial capability toward E. coli (≥99.95%) and S. aureus (≥99.96%) due to the synergistic antibacterial effect. Fe-MoO x exhibited high cell viability and less than 5% hemolysis even under the concentration of 500 μg mL −1 . Based on those unique characteristics, the CCF 0.15 film was chosen for tangerine preservation. The CCF 0.15 film could prolong the shelf life of tangerine by at least 9 days compared with the unpacking group, and the tangerines could maintain the freshness characteristics over a 24 day storage period. Such thermal-mediated antibacterial film proposed by our work showed promising potential in food packaging.
