Mean values with different letter in superscript within rows indicates significant differences (p ≤ 0.05) due to fed. SEM. standard error of least square means.
Time, days of storage at 4°C.
Means of six cheeses for each group with five replicates of measurements at the stated time period.
TBARs, thiobarbituric acid-reactive substances; MDA, malonaldehyde.
