suspension of
the relevant substance, a cold solidification and pressing is carried
out. Followed by a solvent removal step (an evaporation or sublimation),
a porous solid body in the desired mold form is obtained
without using any external pressure (Nguyen and Ulrich, 2014).
Non external pressure and low processing temperature are advantages
which make freeze casting a promising technique for compacting
of heat and pressure sensitive materials, especial in
pharmaceuticals (Pachuski and Ulrich, 2007a,b; Szepes et al.,
2007a,b; Witte and Ulrich, 2010). In addition, a high porosity leads
to a high contact surface area and enhance a dissolution/dispersal
rate of a solid dosage form. Such properties are very useful for fast
dispersal/dissolving products which are of high interests in food
industry e.g. instant foods and in pharmaceutical industry due to
drug delivery issues. In term of a fast dispersal/dissolving tablet,
a high dissolution/dispersal rate is the first order of requirement
