If a College of Creation bard uses their Performance of Creation to summon rations, and then eats the rations, will they still be hungry at the end of their next turn? What if they maintain the summoning for 10 minutes to extend its time to their bard level hours, then do the rations they summon fill creature's hunger?
As an action, you can create one nonmagical
item of your choice in an unoccupied space
within 10 feet of you. The item must appear on a
surface or in a liquid that can support it. The gp
value of the item can’t be more than 20 times
your bard level and must be Large or smaller.
{snip} For examples of items you can
create, see the Armor, Weapons, Adventuring
Gear, Tools, and Mounts and Vehicles tables in
chapter 5, “Equipment,” of the Player’s
Handbook.The created item disappears at the end of your
next turn, unless you use your action to maintain
it. Each time you use your action in this way, the
item’s duration is extended to the end of your
next turn, up to a maximum of 1 minute. If you
maintain the item for the full minute, it
continues to exist for a number of hours equal to
your bard level.Once you create an item with this feature, you
can’t do so again until you finish a long rest or
until you expend a spell slot of 5th level or
higher to use this feature. You can have only one
item created by this feature at a time; if you use
this action and already have an item from this
feature, the first one immediately vanishes.

You can make it, but you won't be nourished
Performance of Creation from the UA College of Creation states:
Once the duration has concluded, the item will disappear. Which means whatever is in your stomach also disappears. You may feel full for a few hours, but that's about it.
What about digestion and evacuation?
This isn't really a part of D&D mechanics, so it'll be up to a DM to decide. If they feel that it's been inside you long enough to be processed and that resulting nutrients remain, which is doubtful as their source is gone as if it was never there, a DM could rule that the effects of eating remain. But that's really up to them.
