Several opinions were expressed regarding bringing mattanos to a Kohen on Yom Tov. According to Rabbi Yosi, everyone agrees that bringing mattanos is permitted on Yom Tov, furthermore, Beis Hillel holds that even bringing Terumah is permitted on Yom Tov.
Rav Yehuda quoting Shmuel: The halacha follows Rabbi Yosi.
Rav Tuvi brei d’Rav Nechemiah had a bottle of terumah wine [they used to separate terumah in Bavel]. He came to Rav Yosef and asked him “Can I bring it to a kohen today?”
Rav Yosef: So said Rav Yehuda quoting Shmuel: The halacha follows Rabbi Yosi.
The host of Rava bar Rav Chanan had bundles of mustard seed plant [which grows in pods], he asked if he can crush the pods in order to extract the seeds to eat on Yom Tov [this can be considered “threshing”, but perhaps a bit between the tips of your fingers is not considered a Melacha]. Rava bar Rav Chanan didn’t know so he came to Rava.
Rava: Beraisa: One may rub ears of fresh grain and crush pods of peas on Yom Tov.
Abayye: Beraisa: One who rubbed grain before Shabbos [and he now has a mixture of the grain and chaff], he may blow it from one hand to the other on Shabbos and eat the grain, but he cannot do it by means of a funnel, or a big pot. One who rubbed grain before Yom Tov, he may blow on it a little at a time and eat it and even by means of a funnel and a pot but not by means of a board or a sieve.
So we see here that it is not permitted on Yom Tov?
