T’vul Yom 3:4

If dough was mixed (with trumah dough) or leavened with trumah yeast, it’s not invalidated by a t’vul yom, though Rabbi Yosi and Rabbi Shimon rule it invalidated. Let’s say that dough was rendered susceptible to ritual impurity by a liquid and it was kneaded with fruit juice, after which it was touched by a t’vul yom. Rabbi Elazar ben Yehuda of Bartosa says in the name of Rabbi Yehoshua that he invalidates the whole thing; Rabbi Akiva says in his name that he only invalidates the part that he touched.

T’vul Yom 3:5

If chulin vegetables were cooked with trumah oil and a t’vul yom touched it, Rabbi Elazar ben Yehuda of Bartosa says in the name of Rabbi Yehoshua that he invalidates the whole thing; Rabbi Akiva says in his name that he only invalidates the part that he touched.
