Division 6.2.1 Titration with hydrochloric acid

United Kingdom

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

\frac{(V_{1} - V_{0}) \times c \times 1,4 \times 6,25}{m}

where:

is the weight (g) of the test portion,

is the concentration (mol/l) of the standard volumetric solution of the hydrochloric acid (3.19),

V₀

is the volume (in ml) of hydrochloric acid used for the blank test,

V₁
