Is this wall in my kitchen load bearing?
I’m glad “you’re going to consult a professional.”

I’m sure he’ll check: 1) that all the trusses are identical, including the connectors, 2) there are no additional loads on the trusses over the kitchen area, like air conditioner, etc., 3) the floor beam is just for floor loading, (the wall does not need to sit directly over the beam in order to transfer the roof load to the floor beam, 4) the wall that is being removed is not for lateral bracing (are you in a high seismic or wind zone), 5) the perimeter footings are not reduced in size by the kitchen area, 

Btw, it’s not just removing the wall...you’ll need to remove/reroute plumbing, electrical, hvac, etc. too.
