Conclusions
The results of this study showed that the ozone treatment increases
pear shelf life with efficient control of microorganisms and does not affect qualitative parameters such as pH and total acidity. It also slows
the increase in total soluble solids, which is indicative of fruit ripening.
However, it is recommended that further studies be undertaken with
different combinations of ozone concentrations and exposure times, as
well as feasibility study on the use of edible films to reduce the fresh
mass loss of ozonized pears.
