The invention relates to a method for classifying portions in which the
cut surfaces of the slices to be removed from a product are detected by
an opto-electronic unit, and the images of cut surfaces are evaluated on
the basis of the proportional presence of the components in the product
and the relative values of the components. Slices of the product which
have identical inner structures within predeterminable tolerance limits
can be combined to form portions of a defined grade.
