A [terumah] apple that was chopped up and placed inside [chullin] dough, and it leavened, Rabbi Yosei says, the leavening [of the apple] is not "leaven" -- regardless of whether it imparted a good taste [to the dough] or whether it imparted a rancid taste, either way it is forbidden, the words of Rabbi Meir. Rabbi Shimon says, [if it imparted] a good taste, it is forbidden, [and if it imparted] a rancid taste, it is permitted, just like [terumah] vinegar that fell into a dish of beans, or a dish of [terumah] beans that fell inside a cistern of water [as all of these worsen the taste of the non-terumah item]. [However,] dates onto which [terumah] wine fell, [or] dried figs onto which [terumah] oil fell, behold these are forbidden. And Rabbi Shimon permits them.
