Can bananas be left in the sun to ripen?

Bananas are a very common fruit in our daily life and are very helpful to our health. Many people who have bought bananas know that bananas are a kind of fruit that is not easy to preserve. This leads to the fact that many times the bananas we buy are not very ripe. Mainly for the purpose of preservation, some people buy less ripe bananas and put them in the sun to ripen them. So what is the ripening effect of bananas in the sun?

1. Apple Ripening Method

Use a cardboard box or plastic bag, add 2-3 ripe apples (or 1 ripe papaya) to bananas, seal it with a plastic bag, and ripen it in 2/3 days at room temperature (do not place it in an air-conditioned room). The banana skin will turn slightly yellow and the flesh will be sweet and delicious.

After waiting for a while, the second night passed. The bananas didn't turn yellow much, but they were soft and very sweet.

2. Rice Ripening Method

Pack the bananas in a plastic bag (no need to seal) and place them in a rice storage container. They will ripen in 2 to 3 days and have a slight rice aroma.

Or put green bananas and rice into a plastic bag, wrap the banana heads with paper towels and seal it.

Banana peel ripening method

Use a fruit foam box, put some yellow ripe bananas or yellow banana peels after eating the plantains, seal them together, place them at normal temperature, and they will ripen in 2/3 days.

If you put green fruits (bananas, papayas, tomatoes, soursop, egg apples, mangoes, persimmons, etc.) in the sun for a few hours and then follow the above method, they will ripen faster.

Notes on ripening bananas

Tiantian Orchard reminds you: Temperature is very important for ripening bananas. If the temperature is low, it will take a long time to ripen bananas and the effect will be poor; if the temperature is too high, for example, over 30℃, the chlorophyll in the banana peel will not disappear, and the lutein and carotene will not appear. In this way, although the banana is soft, the peel is still green. The most suitable ripening temperature is 20℃～25℃.

In addition, the temperature is low in winter, so special attention should be paid to preventing bananas from freezing when ripening. Bananas cannot ripen normally after being frozen for 24 hours at temperatures below 8°C. Therefore, bananas cannot be stored in the refrigerator to keep fresh, as bananas that have been frozen are difficult to ripen again.
