适用范围：Applies to all types of dried milk. The principle is based on the preparation of reconstituted milk by addition of water to a test portion of dried milk. The reconstituted milk is titrated with sodium hydroxide solution using phenolphthalein as indicator and cobalt(II) sulphate as reference colour solution. The number of millilitres used in the titration is multiplied by the factor 2 in order to obtain the number of millilitres required to neutralize a quantity of milk corresponding to 10 g of solids-not-fat.
