For determination of titrable acidity, the titermetric method was used according to the AOAC[4]. The sample taken for determination of cheese acidity was 5 g dispersed in 100 ml of distilled water in 250 ml conical flask, and then six drops of phenolphthalein indicator were added. The sample was then titrated with 0.1N sodium hydroxide until a stable pink color was formed. The titrable acidity was expressed as % lactic acid from the following formula.
