This looks like rope spoilage, and you should discard the banana bread.

I realize I’m replying more than 3 years later, so it’s very unlikely that you still have said bread to discard it.

OK- This happens to me too! I live in Central Florida and after leaving any quick bread with fruit out unrefrigerated the bread will start to do this. Unfortunately I dont know they scientific explanation but I will tell you Im convinced its because its starting to break down and its usually accompanied by a slight off taste like its about to go moldy. When I refrigerate my breads this wont happen. I think the fruit is starting to ferment in my warm environment.

This is my guess too. I think the stretchy strands develop as the liquids begin to separate from the flour. When it combines with the sugar, it gets that stretchy quality.

In tropical countries, sweetened, muffin-like bread is considered stale enough to be discarded, if stretchable, thin transparent threads are seen when a piece is pulled apart. Experience may have shown it can cause illness. Whether it is used as a generic indicator of staleness, or the threads themselves harbor organisms, I do not know. The answer would be interesting to find.

It looks like rope spoilage which is caused by bacteria.

Looks like fiber strands from the bananas.
