Fruits ripen through the production of ethylene gas and so, theoretically, any situation that concentrates the gas given off, will speed up the ripening process. This will occur in the refrigerator, a paper bag, or any other confined space. Keep in mind that a banana is ripe when it is black, not yellow, and so we normally eat bananas in their "green" or unripened state.
It does not matter what brand. Bananas turn brown faster in the refrigerator.
in the refrigerator
The skin goes brown faster in the refrigerator, while the fruit does not ripen further.
on the counter
In the science project determining if a banana browns faster in the refrigerator or on the counter, the independent variable is the location where the banana is stored (refrigerator vs. counter). The dependent variable is the rate of browning of the banana, which can be measured by factors such as time taken to brown or the extent of browning observed.
Because banana's grow in a hot country so do not cold conditions such as fridges or freezers!
the refrigerator
because the refrigerator keeps it fresh and at one temperature. the counter changes temperature. Acetylene gas in the confinement of refrigerator hastens the browning process in banana.
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.
Take two bananas on the same stem, separate them and place one in the refrigerator and the other on the counter to see which will brown faster.
because the refrigerated heat carbons take out the orginated cells quicker.
A banana will turn brown whether or not it is in a refrigerator. However, a banana will turn brown faster in a cold space, such as refrigerator, than if left in a space that is at room temperature. The skin of a banana turns brown or black faster in a refrigerator, but the banana meat itself does not ripen that much more. In fact, it is recommended that ripened bananas be frozen to preserve them even longer. The cold temperature of a refrigerator encourages an enzyme (polyphenyl oxidase), which is naturally found in the banana, to polymerise phenols in the banana skin into polyphenols. Polyphenols are similar to melanin, the pigment responsible for the color in our skin. This is what blackens the skin of the bananas. Despite the color, the cold temperature will keep bananas firmer than a banana that has been left at room temperature for the same amount of time. The enzymes that break the starch into sugar, which makes the banana soft and ripe, work better at room temperature.
