Baby gagging???

Ok so my LO still doesn't have teeth, but we're trying different table foods. She's done pretty good so far, BUT there has been a few times where I put the food on her tray, like for example yesterday we tried green beans and carrots and then some banana after that, and she's had all these things before, but she hasn't even put the food up to her mouth yet and she's gagging! Im trying to figure out why, I know it's not cause she doesn't like it because she loves bananas for sure she eats them all the time. Could it be maybe that shes just not hungry? I would understand if she gagged once it was in her mouth cause she's not hungry, but she's literally just playing with the food with her hands and gagging ☹☹😫😫😖😖🤨🤨
