The aim of this study was to assess the antioxidant effect of concentrated oil macerate of sage in inhibiting the oxidation of fish oil. The results showed that sage macerate contained polyphenols and pigments, which exhibited antioxidant properties and effectively inhibited the oxidation of fish oil.
The aim of the study was to assess the antioxidant effect of concentrated oil macerate of sage (M) as a green extract in inhibiting the oxidation of Fish Oil (FO). In the homogenization-assisted maceration process, FO was used as a solvent for the sage active substances to produce M, which was then added to FO (25% w/w) and evaluated for its effect by monitoring the level of oxidation during refrigerated and room temperature storage. The macerate also examined polyphenols, plant pigments, DPPH antioxidant potential, oxidation level and sensory quality. It was shown that the maceration process made it possible to obtain aromatized M, containing polyphenols (carnosic acid, carnosol) and pigments, but with an increased level of peroxides, free fatty acids, compared to the control oil. M showed antioxidant properties and inhibited FO oxidation. It showed the best efficiency in FO during refrigerated storage, in the third month it reduced the level of peroxides by about 9 times, compared to the control. M retains unchanged quality at refrigerated temperature for up to 3 months. Sage macerates are green extracts that can be used as effective natural antioxidant additives, following preparation improvements to reduce the amount of peroxide formed.
