Why do fruits deteriorate after ripening

The higher the brix levels, the higher the sugar and mineral content will be in the fruits and vegetables. On the other hand, fruits and vegetables that are poor brix levels, will often decompose quickly when left out at room temperature.

Food can be broken down initially by chemical reactions. For example, when apples are exposed to oxygen, a chemical reaction takes place called oxidization. This causes the apple to turn brown. Explain to students that some things slow down the decomposition of food, while other things make it happen more quickly. Some fruits ripen after they are picked.

Strawberries, cherries and grapes ripen on the plant. Once you pick them, they may get softer due to the natural deterioration of plant matter, but they will never get any sweeter.

Once picked, these fruits are as ripe as they will ever get. Other fruits that fall into this category are apples, blueberries, raspberries, tangerines, oranges, limes and blackberries. Ripening after Picking. Other fruits continue to ripen after picking.

If the fruit is left on the plant long enough, the plant will send the signal. But the signal can also be triggered by a wound to the plant. The wound made when the fruit is cut from the plant can actually trigger ripening. These kinds of fruits--avocados, bananas, mangoes, pears, plums and tomatoes--will stop ripening if you put them in the refrigerator.

For best quality, ripen them at room temperature in a brown paper bag. When the fruit is fully ripe, you can store it in the refrigerator to stop it from over-ripening or spoiling. Refrigeration and Spoilage. All fruit can spoil. Ripe fruit spoils more quickly than unripe fruit. One of the reasons fruit spoils is bacteria, mold and fungus. If you have ever forgotten about a peach only to find it covered in blue or green mold, you are familiar with this kind of spoilage.

Refrigeration slows the growth of these microbes. In doing so it buys you a little bit of time between the time your fruit is fully ripe and the time it starts to deteriorate.

Cut Fruit. Fresh cut fruit always requires refrigeration. Whether the fruit was cut before you bought it or whether you cut it up, that fruit needs to be refrigerated. Micro-organisms speed produce deterioration through structural decay. The fruit that rots quickest are the softer fruits such as berries, bananas, peaches, plums, kiwis, satsumas and clementines as well as tomatoes, kale, spinach, lettuce — to name but a few!
