Does vinegar make bananas not turn brown?

Yes, vinegar can help prevent bananas from turning brown. The browning of bananas is caused by an enzyme called polyphenol oxidase, which reacts with oxygen to produce melanin. Vinegar is acidic, and the acid in vinegar can inhibit the activity of polyphenol oxidase, thereby slowing down the browning process.

To prevent bananas from turning brown, you can dip them in a solution of vinegar and water before storing them. The vinegar solution should be about 1 part vinegar to 4 parts water. You can also spray the bananas with vinegar solution or place a bowl of vinegar near the bananas.

Vinegar is a natural and safe way to prevent bananas from turning brown, and it does not alter the taste or texture of the bananas.
