Then all the selected plain set yoghurt samples were test for organoleptic characters such as color aroma appearance thickness taste sourness sweetness and over all acceptability. After that all the selected plain set yoghurt samples were analyzed with their physical and chemical parameters such as syneresis effect pH titratable acidity total protein content. By doing analysis of sensory evaluation the brand 12 was the least acceptable product while brand 15 was the most acceptable product by thirty untrained panelists.
