2.6. Sensory Analysis
Sensory evaluation was performed by 20 panelists, after seven days of storage at 30+2°C, on samples that had been dipped in 1; 1.5; 2% (w/w) of chitosan (DD: 70%; 80%) in 0.6% acetic acid or dipped in this solution by using triethanolamine as emulsifier. Multiple comparison tests with a six point numerical scale performed to distinguish level of several sensory parameters among chitosan coated samples within the specified DD. The parameters evaluated were color, aroma, and texture. The following numerical scale was used for scoring these attributes: 1. very good, 2. good, 3. slightly good, 4. slightly bad, 5. bad and, 6. very bad.
