Calculation
Calculate the fat content according to the
formula below.
W3 = The extraction cup weight after fat
extraction and cooling in desiccator.
W2 = Clean and predried extraction cup.
W1 = Sample weight.
% Fat
=
W3-W2
x 100
W1
If a pre-extraction was required, using two
extraction cups, add the two results that have
been calculated, and the sum is the total fat
in the sample.
F1 = Fat content after pre-extraction.
F2 = Fat content in final extraction.
% Fat/Oil = F1 + F2
