Abstract

This study aimed to investigate the antibacterial activity of inclusion complexes of allyl isothiocyanate (AIT), beta- and alpha-cyclodextrin. In order to carry out these fictitious experiments, the target pathogen was plated onto the agar surface of a Petri dish, and the AIT formulations were spotted onto filter paper discs that were then adhered inside the dish's lid. The concentrations of AIT formulations in the static headspace were measured using solid phase microextraction and gas chromatography. By storing freshly cut onions at 5 °C for 20 days in sealed containers, beta IC's antibacterial effectiveness was evaluated. AIT that had been beta IC-encapsulated had better antimicrobial effectiveness than AIT that had not been encapsulated (p 0.05). In the static system, unentrapped AIT had the highest vapor concentrations, followed by beta IC and then alpha IC. significant reduction in L. When fresh-cut onions were exposed to beta IC (200 l/l) before being packaged, monocytogenes was found, but a smaller decrease in the number of L was seen. monocytogenes found in the raw, cut onion. The total aerobic count in onions was about 4 log CFU/g lower than in controls after 10 days of treatment with beta IC. Based on these results, beta IC might be used as an antibacterial treatment in pre-packaged fresh-cut vegetables.
