Bananas in the fridge turn brown due to a natural enzyme called polyphenol oxidase reacting with oxygen in the air, causing the fruit to oxidize and change color.
Potatoes turn purple in the fridge due to a natural reaction between the starches in the potato and the cold temperature, which causes a buildup of sugars and anthocyanin pigments.
When blood is exposed to air, it typically takes about 5-10 minutes for it to turn brown due to the oxidation of hemoglobin.
Enzymatic browning is a chemical reaction that occurs in certain foods when enzymes and oxygen interact, causing the food to turn brown. This process is commonly seen in fruits like apples and bananas when they are cut and exposed to air. Substances like lemon juice or ascorbic acid can help prevent enzymatic browning by inhibiting the enzymes involved.
Blood turns brown when it is exposed to air for a period of time because the iron in the hemoglobin molecules oxidizes, causing the blood to change color.
In the fall, a leaf can turn various shades of red, orange, yellow, or brown.
two bananas, a counter, a fridge, and some time.
because if you leave it out it will rot and turn brown
Yes.

Bananas should be slower to turn brown if treated with Fruit Fresh.
Yes.
Not for long. They turn brown and yucky.
Yes, due to much sugar and potassium contained in bananas.
Bananas are green, but when they are ripe they turn yellow. When they are rotten, they get brown blotches and eventually turn all the way brown.
The banana in the refrigerator browned faster than the banana on the counter. The cold temperature makes a banana's skin brown faster. The banana in the refrigerator is still firm though, where as the banana on the counter is softer.
Bananas can last in the fridge for about 2-3 days before they start to spoil.
