Question

Use this scenario to answer the question.

After eating half of a banana as a snack, you decide to save the rest for later. There are two types of plastic wrap in your house, and you use one to cover the banana. In an hour, you return and find that your banana half has browned significantly despite being saved in plastic wrap. You discover that one of the plastic wraps is made of polyvinyl, and the other is made of polyethylene.

Which plastic wrap could have caused this browning effect, and why?

The polyethylene wrap probably caused the browning since it contains ethylene which would speed up the ripening process.

The polyvinyl wrap probably caused the browning since it traps ethylene gas which would delay the ripening process.

The correct response is:

The polyethylene wrap probably caused the browning since it contains ethylene which would speed up the ripening process.

Ethylene is a natural plant hormone produced by fruits, including bananas, that promotes ripening. If the polyethylene wrap allows for ethylene to build up, it could hasten the ripening process and consequently lead to browning. In contrast, polyvinyl (as a plastic) tends to trap ethylene gases, which might not significantly accelerate the ripening process as much as polyethylene would. Thus, the use of polyethylene wrap could be more likely to cause browning due to its interaction with ethylene.
