Sensory tests were carried out in a standardised room. A total of 40 subjects had participated for sensory studies which included 20 trained taste panel staff members and 20 students from the Food Science and Technology Department, Faculty of Agriculture, Alexandria University. The panelists were from both sexes (aged 22–48 years) who volunteered for the study. The subjects were trained adequately in identifying tastes of various test molecules before the commencement of the tests.
