Impacts of chitosan/pullulan/carvacrol film on the quality and microbial diversity of refrigerated goat meat.

In this study, our previously prepared chitosan/pullulan film (CS/PU) and chitosan/pullulan/carvacrol film (CS/PU/CAR) were applied to goat meat preservation, the dynamic changes in quality and microbial communities of goat meat during chilled storage (4 °C) were investigated, and the fresh-keeping effects of the two biodegradable antibacterial films on goat meat were comprehensively evaluated. The results showed that when the goat meat was wrapped with CS/PU or CS/PU/CAR films during chilled storage, the total plate count and total volatile basic nitrogen (TVB-N) could be inhibited significantly, but the CS/PU/CAR film has a better fresh-keeping effect. Furthermore, during the chilled storage of goat meat, CS/PU/CAR film also could inhibit the production of alcohol compounds and the growth of Pseudomonas spp.

Fabrication and characterization of carvacrol encapsulated gelatin/chitosan composite nanofiber membrane as active packaging material.

In this study, carvacrol was effectively encapsulated in gelatin/chitosan composite nanofiber membrane using the electrospinning method with the help of the cationic surfactant cetyltrimethylammonium bromide (CTAB). The effects of CTAB (0.0%, 1.

Preparation and characterization of chitosan/pullulan film loading carvacrol for targeted antibacterial packaging of chilled meat.

In this research, the common microorganisms in chilled meat were used as the targeted antibacterial objects. Chitosan, pullulan, and carvacrol were chosen to prepare the edible antibacterial film. The effects of different concentrations of carvacrol on the microstructure, physical properties and antibacterial properties of the films were investigated.
