משנה אויף שמות 27:1

They should not take terumah from olives for oil, or from grapes for wine. If one did: Bet Shammai says: there is terumah in [the olives or grapes] themselves. But Bet Hillel says: the terumah is not terumah.

In the case of hallah and terumah:One is liable for death on account of [having eaten] them death [intentionally], or to [repay] an added fifth [if unwittingly]; They are forbidden to non-priests; They are the property of the priest; They are nullified [in a mixture of] one-hundred-and-one [parts, the rest being non-sacred dough or produce]; They require washing of one’s hands; And [waiting until] the setting of the sun [prior to eating them]; They may not be separated from pure [stuff] for impure; But rather from that which is close, And from that [in a] finished [state]. If one said: “All my threshing-floor is terumah, or all my dough is hallah,” he has not said anything, unless he has left some over.

Regarding terumah and bikkurim:One is liable to death And the [additional] fifth; And they are forbidden to non-priests; And they are the property of the priest; And they are neutralized in a hundred and one parts; And they require the washing of hands; And the setting of the sun. These [laws] apply only to terumah and bikkurim, but not to tithe.
