Abstract

In accordance to the results, the isothiocyanate (ITC) concentrations of different wasabi pastes were determined and samples A, B, and, C have ITC concentrations of 2.170, 1.908, 0.993 mg/g, respectively. This means that the concentrations vary at a significant level. Also the Decimal Reduction Time (Dvalue) of Escherichia coli in wasabi paste samples was determined and the Dvalues of samples A, B, and, C were 142.51, 170.67, and 261.99 hours, respectively. This signifies that the higher ITC concentration of wasabi paste sample yields a lower D-value which means better antimicrobial effect. Lastly, the ITC concentrations of wasabi pastes and the D-values of E.coli were associated. It is found that there is a 99% correlation between the ITC concentrations and the D-values.
