Division 6.1 Calculation for titration according to 5.3.1

United Kingdom

The content of crude protein, expressed as a percentage by weight, is calculated according to the following formula:

\frac{(V_{0} - V_{1}) \times c \times 0,014 \times 100 \times 6,25}{m}

where:

V_o

is the volume (ml) of NaOH (3.10 or 3.11) used in the blank test,

V₁

is the volume (ml) of NaOH (3.10 or 3.11) used in the sample titration,

is the concentration (mol/l) of sodium hydroxide (3.10 or 3.11),

is the weight (g) of sample.
