2.2. Pre-treatments
For this study fresh and tender carrots were selected and washed thoroughly with potable water. The carrots were then cut into 5 mm thick slices. For experimental studies the prepared carrot slices were blanched for 5 min. in boiling water. Three solutions were prepared in three different pans. These solution were contained 0.1% KMS (Potassium Meta bi-Sulphite), 0.2% KMS, and 0.3% KMS, respectively. Then prepared carrot slices were soaked in those solutions for 5 minutes. After 5 minutes, the carrot slices were separated from the solution and the surface water of carrot slices were removed by blotting with filter paper.
