Abstract

The freeze-dried concentrate of green mussel, Perna viridis, was added with naturally derived antioxidative oleoresins of rosemary and turmeric along with trace amounts of other natural additives to prepare different treatments and was subjected to accelerated shelf life study (50°C) to evaluate its oxidative stability. The total oxyradical scavenging activities of samples with higher concentrations of turmeric over rosemary demonstrated the prominent role of the turmeric extracts to arrest free radical chain reactions. Time dependent antioxidative status in relation to the nutritional compositions was evaluated to identify the oxidative changes for different treatments. The addition of natural additives with polyphenolic moieties in the treatments shielded the mussel’s unsaturated fatty acids against oxidation as evident by higher polyunsaturated fatty acids in the two treatments as compared to control after 90 days of accelerated shelf-life study. Higher n-3/n-6 ratios after 90 days’ storage were also observed in these treatments. A threshold level of combined turmeric (0.8 g/100 g) and rosemary (0.4 g/ 100 g) was sufficient for optimum antioxidant activity and to maintain nutritional composition of the green mussel extract at desired levels.
