According to the above link, isoamyl acetate smells like pears or
bananas. Wrong chemical.

According to the above link, ethyl acetate has a pleasant fruity odor.
Again, wrong chemical.

Neither ethyl acetate or isoamyl acetate are responsble for the ripe
fruit odor.

The OSHA descriptions are how they smell to the rest of us.
Not necessarily you. You'll need to smell them yourself
to determine if they match with what is bothering you.
Pineapple has a lot of ethyl acetate. Bananas have a lot
of isoamyl acetate.
