There are a few simple ways to store bananas to keep them fresh for several days or even weeks. The first step is to select ripe bananas. Bananas that are ripe will have yellow skin with a few brown spots. Avoid bananas that are underripe (green) or overripe (black). Then store the bananas at room temperature, away from direct sunlight. The ideal temperature is between 65 and 70 degrees Fahrenheit. You can also store the bananas in a brown paper bag to trap the ethylene gas that the bananas produce, which will help them to ripen evenly.
Another way to store bananas is to place them in the refrigerator. Bananas can be stored in the fridge for up to two weeks, but they will turn brown. To prevent this, you can wrap the stems of the bananas in plastic wrap or foil. Alternatively, you can place the bananas in a resealable plastic bag and squeeze out as much air as possible before sealing the bag. If you want to freeze bananas for later use, peel them first and then place them in a freezer-safe container or bag. Bananas can be frozen for up to six months.
Another great way to keep bananas fresh is to make banana chips. Simply slice the bananas into thin pieces, then bake them in the oven at a low temperature until they are dried out. Banana chips can be stored in an airtight container for several weeks.
You can also make banana bread or muffins to keep the bananas fresh for a longer period of time. Banana bread and muffins can be stored in the freezer for up to three months. Just be sure to wrap them tightly to prevent freezer burn.
