When separating all the relevant tithes from one's produce, one can include all the various obligations in one collective blessing before the entire process (Tosefta Brachot 6:19 (note variant versions), Yerushalmi Demai 5:2 (cf. Shu"t Rivash 384), Rambam Maaserot 1:16 (see also Terumot 2:16), Shulchan Aruch YD 331:78). The blessing, as printed in all prayer books today, is:
ברוך אתה ה' אלקינו מלך העולם אשר קדשנו במצוותיו וצונו להפריש תרומות ומעשרות.
Blessed are You, Lord our God, King of the universe, Who has sanctified us with His commandments and commanded us to separate the heave offerings and tithes.
What would the appropriate formulation of the blessing be for each separation individually? I'm looking for the correct blessing(s), if any, to say before all instances of separating exactly one of: Terumah Gedolah, Terumat Maaser, Maaser Rishon, Maaser Sheni, and Maaser Ani.
