The skin turns brown or black faster in the 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.

What is the independent and the dependent variable in the science project determining if a banana brown faster in the refrigerator or 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.
