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, phys. properties and antibacterial properties of the films were investigated. The results showed that the antibacterial activity of chitosan/pullulan film (CS/PU) was unsatisfactory, when carvacrol was added, the antibacterial activity of the chitosan/pullulan/carvacrol film (CS/PU/CAR) improved significantly (p < 0.05), and the water vapor permeability (WVP) of the CS/PU/CAR decreased significantly (p < 0.05). When the carvacrol concentration was higher than 1.25% (w/v), the tensile strength and percentage elongation at break of the CS/PU/CAR increased significantly (p < 0.05), and the CS/PU/CAR exhibited satisfying antibacterial activity against the common bacteria in chilled meat such as Pseudomonas fluorescens, Listeria monocytogenes, Escherichia coli, Pseudomonas putida, Enterobacter cloacae, and Staphylococcus aureus. Finally, the CS/PU/CAR film was applied to the preservation of chilled goat meat and extended the shelf life of goat meat to more than 15 days. These results suggested that the targeted CS/PU/CAR film can be used as biodegradable films for the active packaging of chilled meat. In the experiment, the researchers used many compounds, for example, 5-Isopropyl-2-methylphenol (cas: 499-75-2Recommanded Product: 499-75-2).
5-Isopropyl-2-methylphenol (cas: 499-75-2) belongs to alcohols. A strong base can deprotonate an alcohol to yield an alkoxide ion (R―O−). For example, sodamide (NaNH2), a very strong base, abstracts the hydrogen atom of an alcohol. Grignard and organolithium reagents are powerful tools for organic synthesis, and the most common products of their reactions are alcohols.Recommanded Product: 499-75-2
