The analysis of variance showed no significant difference (p>0.05)
for titratable acidity (TA) and pH from the interaction of treatment or
no treatment with ozone and the storage period. The means for TA
and pH of fruits untreated and treated with ozone for 13 days are
presented in Figures 3 and 4. Similarly, Holtz [29] found no significant
differences for pH in strawberry untreated and treated with 50 ppm
ozone for 30 and 60 minutes over 15 days of storage.
