However, in spite of the larger size of the particles in the mixed fruit
powder, the density–pressure curves were almost alike with guava
powder. This is attributed to the moisture content and agglomeration
of the mixed fruit powder during mixing. The blending of guava and
pitaya powders reduced the porosity by accommodating the lower
pitaya particles within the void of larger guava particles, thus resulting
in the mixed powder with higher porosity. The complex interaction of
moisture content, agglomeration and increased porosity of the mixed
