Becker, Miers, Nutting, Dietrich, and Wagner (1972) studied the
dimensions of tomato cells and found values between 400 μm×600 μm
and 600 μm×1000 μm. Thus, it is to be expected that the control juice,
with particle diameters ranging between ~100 μm and ~1000 μm,
would be constituted of some whole cells and their fragments, obtained
during processing of the tomato pulp. As explained by Augusto et al.
(2012b), the homogenization process disrupts the remaining cells and
breaks their fragments into small suspended particles. It is to be expected
that the smaller fragmentswould be less susceptible to being broken during
processing when compared to the bigger ones or even to the whole
cells, which explains the observed effect of PH on the suspended particle
disruption behavior, which was further confirmed by the microstructure
analyses.
