Concerning the problem of sub-lethal injured cells, their
behaviour during the storage of the smoothies should not be
overlooked. Such an intermediate physiological state prevailing in
the survivor population of the most effective treatments could be
recovered by the residual metabolic activity in permissive environmental
conditions, which differs from the conditions of
smoothies. These aspects have been investigated in our laboratory
(Zacconi & Scolari, submitted for publication) as an important
factor in determining the applicability and safety of pressure
treatments in the smoothies industry.
