#Juice that oozed out of a fruit by itself, if the fruit was meant to be eaten, it is permitted to drink that juice, however, if the fruit was meant to be squeezed for its juice the juice that came out on its own is forbidden.<ref>Shulchan Aruch O.C. 320:1, Shemirat Shabbat KeHilchata 5:11.
See Chazon Ovadia Shabbat Vol. 4, who permits the drinking of juice that came out on its own only for fruits with a derabanan sechita prohibition (and those fruits are designated for eating). </ref>
#For example, if someone cut watermelon or grapefruit to eat it and juice oozed out it is permitted to drink the juice.<ref>Shemirat Shabbat Kehilchata 5:11-12</ref>
