L*, lightness; a*, redness; b*, yellowness; ΔE, color different.
CON, no treatment; CM, applied only 1.5% carboxymethyl cellulose and 2.0% Tween80; CM-G, applied CM + 1.5% green tea extract; CM-R, applied CM + 1.5% Rhus chinensis extract; CM-B, applied CM + rice bran extract; CM-M, applied CM + 1.5% Morus alba extract.
Values are mean±SD of triplicate determinations.
Different small letters mean in a between groups of samples by different superscripts are significantly different (p<0.05) by Duncan’s multiple range test.
Different capital letters mean in a between groups of storage period by different superscripts are significantly different (p<0.05) by Duncan's multiple range test.
Means in a between groups of sample on 12 days are significantly different (*p<0.05, **p<0.01) by t-test.
Samples were determined to be unsuitable for use in the experiment and were excluded from the experiment.
