Abstract In this study, we compared the effects of tert-butylhydroquinone (TBHQ), quinol dimethacrylate (trolox) and L-cysteine (L-Cys) on the lipid oxidation and volatile flavor components in dry-cured Spanish mackerel (Scomberomorus niphonius). The changes of pH value, lipid oxidation measures such as acid value (AV), peroxide value (POV) and malondialdehyde (MDA) content, 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging capacity and volatile flavor components were measured. The results showed that compared with the control group, AV, POV and MDA content declined by at least 1.18 mg/g, 0.28 g/100 g and 66.68 mg/kg after soaking treatment with 0.02% antioxidants, respectively, DPPH radical scavenging capacity increased by 9.80%, whereas no apparent changes of pH value were observed. The inhibitory effects of the three antioxidants were in decreasing order of trolox > L-Cys > TBHQ. Furthermore, the antioxidants decreased the relative amount of volatile flavor components in dry-cured Spanish mackerel. The number of key flavor components in the TBHQ, trolox, L-Cys and control groups was 11, 3, 11 and 13, respectively. Only the L-Cys group had key flavor components similar to those of the control group, showing that L-Cys has minimal impact on the characteristic flavor of dry-cured Spanish mackerel. In conclusion, L-Cys can be used instead of synthetic antioxidants for inhibiting lipid oxidation in dry-cured fish products.
