We may not separate oil as terumah on behalf of crushed olives, nor wine on behalf of pressed grapes. If one separated te-rumah [thus], his terumah is terumah, but he must separate terumah again. The first [terumah] renders a mixture forbidden by itself, and we are liable to [a surcharge of] a fifth for it, but not the second [terumah].

But we may separate oil as terumah on behalf of preserved olives, and wine on behalf of grapes that will be made into raisins. If one separated oil as terumah on behalf of olives [used] for eating or olives on behalf of olives [used] for eating, or wine on behalf of grapes [used] for eating or grapes on behalf of grapes [used] for eating, and he reconsiders [and decides] to press them, he need not separate terumah [again].

We may not separate terumah from an item whose processing is completed on behalf of an item whose processing is not com-pleted, nor from an item whose processing is not completed on behalf of an item whose processing is completed, nor from an item whose processing is not completed on behalf of an item whose processing is not completed. But if they separated te-rumah [thus], their terumah is terumah.

We may not separate terumah from tahor [produce] on behalf of tamei [produce]. But if they separated terumah [thus], their terumah is terumah. In truth, they said: [Regarding] a round cake of pressed figs part of which became tamei, one may separate terumah from the tahor [figs] it contains on behalf of the tamei [figs] it contains, and likewise for a bundle of vegetables, and likewise for a pile [of produce]. If there were two round cakes [of figs], two bundles [of vegetables], or two piles [of produce], one [of which is] tamei and one [of which is] tahor, one may not separate terumah from this [one] on behalf of that [one].  Rab-bi Eliezer says: We may separate terumah from tahor [produce] on behalf of tamei [produce].
