Division 7.1: Formula and method of calculation - First Commission Directive of 25 October 1985 on methods of analysis for edible caseins and caseinates (85/503/EEC)

The titratable acidity of the acid casein is given by:

\frac{20 × V × T}{m}

where:

V

is the volume, in millilitres, of the standard volumetric sodium hydroxide solution (4.1) used;

T

is the strength of the standard volumetric sodium hydroxide solution (4.1) in mol/1;

m

is the mass, in grams, of the test portion.

Calculate the titratable acidity to two decimal places.
