where Ceff;w=w and Ccont;w=w are the protein concentration of the dispersion
and the continuous phase in weight per weight respectively,
and G the weight fraction of the pellet. It was assumed that
the pellet consisted mostly of protein. This may not be the case,
as the maximum packing fraction determines the total volume fraction
of the particles, function of the shape of the particle. However,
this approximation allowed to estimate a total volume fraction of
the protein particles.
