Values are means standard deviation of three replicates.

^a-dMeans in the same column with different superscript letters are different (p<0.05).

^A-DMeans in the same row with different superscript letters are different (p<0.05).

¹⁾Hunter L=Lightness (100=white, 0=black).

²⁾Hunter a=Redness (+, red; −, green).

³⁾Hunter b=Yellowness (+, yellow; −, blue).

⁴⁾TBA=Tthiobarbituric acid (mg MDA/kg sample).
