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

Extent: E+W+S+N.I.

The titratable acidity of the acid casein is given by:
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.
