When bananas are peeled -- whether left whole or cut into pieces -- they begin to turn brown due to a process called oxidation. Although oxidation doesn't alter the flavor of the bananas, it can make them soft and unappealing. While sometimes brown bananas are ideal, as in the case of banana bread, most of the time slices that look, taste and have the texture of fresh bananas are most desired. Quick preventive measures can allow peeled bananas to retain their natural color and flavor for four to five days.
Banana slices add natural sweetness and a soft texture when mixed with other fruits in a fruit salad. As the sliced bananas are exposed to the air and sugars from other fruits, they tend to brown and become softer. This change, due to oxidation, doesn't alter the taste of the bananas but makes them less appealing to the eye. Rather than picking out the bananas or throwing away the fruit salad, a little preparation can help preserve the banana.
From the moment bananas are harvested, intense, complicated and elaborate procedures are put into motion to control the ripening process. The bananas are harvested, treated, wrapped and packed in shipping containers. Temperature, humidity, exposure to light and the application of ethylene gas ripen the fruit in stages from the grower to the grocer's shelf. Consumers may select firm bananas that are uniformly yellow-green to bright yellow, depending upon the stage of ripeness desired. Bananas contain an enzyme called polyphenol oxidase, which when exposed to air reacts by causing browning of the fruit. The application of an acidic juice inactivates the…
Banana cream pie and other pies containing sliced bananas make for yummy desserts. However, sliced bananas in the pie can turn brown and slimy within a day or two. When any fruit is sliced open and exposed to oxygen, especially bananas, the fruit starts to turn brown and decay faster. To keep your sliced bananas firm and fresh, there are a few simple techniques to follow.
Rich in potassium and vitamins, bananas are a healthy and tasty snack that are often used in cakes, desserts and salads. While best enjoyed before they fully ripen, once peeled and exposed to air bananas will quickly turn brown and soften, which often reduces their visual appeal and loses some of their taste. Bananas are preserved best in a refrigerator instead of a display bowl at room temperature; although the skin will go brown the fruit itself will remain edible and fresh for several days.
Nothing is more unappetizing than cutting into a banana pie and finding that the bananas have turned brown. Bananas quickly turn brown when peeled and exposed to air, but there is a way to keep them fresh for pies and puddings. A perfect, yummy looking pie will be the final result if you add a few quick steps during the preparation.
