Means in rows with different superscripts markedly differ, P < 0.05. n = 8
Treatments: FO means fresh oil; OO means oxidized oil; FO + AOX means fresh oil plus AOX; OO + AOX means oxidized oil plus AOX
^a,bMean values within a row with unlike superscript letters were significantly different (P < 0.05)
