even higher than the freeze dried sample. The comparison of the three samples to
the uniform powder value leads to information about the porosities of the particles. The difference
between particle and powder value corresponds to a gas volume included and non-accessible within the
solid. This value is very important for the product quality, as it influences the dissolution properties of the
product. Additionally if the real density is lower than the density of water, the product will float and
therefore will not dissolve easily in water.
