Freezing after superheated steam	49.39±1.78 b	28.11±0.81 a	41.78±0.87 ab	2.36±0.82

Means with different superscripts within the same column are significantly different (p<0.05).
The values were represented as the mean values (n>9).
The total color difference is calculated compare to thermal treated carrots.
