3.3. Antioxidant activity against the OH-radical in FMS
The DPPH radical is not representative of reactive oxygen gen-erated in vivo. The antioxidant activity against the OH-radical of FMS at 24 weeks was investigated and compared to other commer-cial fermented sauces in a of OH-radical scavenging activity assay (Fig. 4). Although the activity of anchovy fish sauce 1 could not be mea-sured in this study, antioxidant activity against the OH-radical in puffer fish sauce (88.6 ± 6.3%) was the highest in the seven kinds of fermented sauces investigated, and the activity of FMS (61.2 ± 8.4%) was the second highest. Furthermore, it was shown that FMS had significantly higher (p < 0.05) activity than that of the chicken sauce (25.1 ± 8.4%) and soy sauce (22.4 ± 3.8%). This could also be generated by fermentation, similar to the observa-tions with DPPH radical scavenging activity, although changes in
