Fruit ripens. We all know that. It gets softer, less green and often sweeter even though there’s a higher acidity level.
Not all fruit ripens at the same speed, however, and sometimes it’s possible to speed up or slow down a fruit's ripening process.
If you want a banana to ripen fast, you should keep it in its bunch, and if you want it to last a little longer before ripening, separate it.
It’s been shown that when a banana is separated from the bunch, it takes longer to ripen.
Around the world, people have been speeding up the process of ripening for thousands of years. Ancient Egyptian harvesters slashed open the figs they collected to stimulate ripening, and Chinese farmers would leave pears in closed rooms with incense burning.
Both of these things have been proven to speed up ripening.
