Abstract
In order to identify nutraceutical functions of fermented fish and shellfish sauces, which are highly appreciated in food products in South-East Asia, the antioxidative activity of fermented blue mussel sauce (FBMS) was investigated. The blue mussel was fermented with 25% NaCl (w/w) at 20±0.5 °C for 12 months and the fermented sauce was passed bimonthly through a 40-mesh sieve, desalted using an electrodialyzer, and then lyophilized. The antioxidative activity of FBMSs was investigated and compared with that of a natural antioxidant, α-tocopherol standing as a reference. Using consecutive chromatographic methods, the antioxidative peptide with a molecular mass of 620 Da was purified from 6-month-fermented sauce, and its sequence of the peptide was FGHPY. In addition, 64.8 μM of the purified peptide could scavenge 89.5% of hydroxyl radical in radical scavenging assay using electron spin resonance spectroscopy.
