Hilchos Bikkurim 1:3

Eight of the gifts given to kohanim may only be eaten in the Temple, inside the walls of the courtyard; five of them may only be eaten in Jerusalem, inside the city walls. Under Biblical law, five of the gifts are only acquired in Israel, five are acquired both in Israel and elsewhere, and one is acquired from Temple property.

Hilchos Bikkurim 1:4

The eight that are only eaten in Temple are the meat of sin offerings, whether of birds or of animals; the meat of a guilt offerings, both definite guilt offerings and conditional guilt offerings; communal peace offerings; the remainder of the omer; the remainder of a Yisroel’s flour offering; the two loaves (brought on Shavuos); the showbread; the log of oil of a metzora. These may only be eaten in the Temple.
