AnV, p-anisidine value; CAT, catalase; DDE, 2,4-decadienal; FA, fatty acid; GPx, glutathione peroxidase; HNE, 4-hydroxynonenal; ISP, F2-isoprostane; IV, iodine value; ND, not detected; OFA, oxidized fatty acids; OSI, oil stability index; PTAG, polymerized tryacylglycerides; PV, peroxide value; TBA, thiobarbituric acid; TBARS, thiobarbituric acid reactive substances; TOC, tocopherol; TPC, total polar compounds; UFA:SFA, unsaturated:saturated fatty acid ratio.
Ratio, ratio of aldehydes as described by Wang et al. (2016).
1Top value represents correlation (R value) and bottom value in parenthesis represents significance (P value). If no value is given, it was not found to be significant (–) at P <0.05. There were no correlations observed between SO quality indices and plasma TBARS, plasma PC, plasma GPx, liver TBARS, liver 8-OH-2dG, liver CAT, or urinary 8-OH-2dG so they were removed from the table.
