Why fruits and vegetables turn rot?

If you ever been ask of the reason why fruits and vegetables turn rot, i'm sure it's familiar that most of them will jump into the solution that's because of BACTERIA or MICROORANISMS！！

Well, let's not aim on bacteria and microoganisms, do you ever wonder what's other factors which cause the spoiled of fruits anf vegetables?

We can ever denied that fresh fruits and vegetables is always so delicious and healthy! However, they have their own shelf life. NOW, let's straight into the point...

Have you ever wonder that fruits and vegetables respire just like the tree, brushes and vines? YES,they do! Just like we breathe in oxygen and expell carbon dioxide and fruits is vice versa. The faster they respire, the faster they ripe and rot. Thus, we keep fruits and vegetables in fridge to slown down their ripening and rottoning. In other words, to maintain the quality of food.

Nevertheless, the fruits and vegetables get gas too! They emit an odorless, colorless gas call enthylene. Do you haver wonder why an rotton apple spoilt the whole barrel? That's because the detection of enthylene sparks the production of more enthylene! Basically, an rotton apple will emit lots of enthylene gas, which leads to the emitting of gas of others apple, and sooner or later the apple will ripe, and eventually rot! The same things happen to the others fruits or veges in the fridge, where all of them have the receptor to sense the enthylene gas.

After the fruits or vegetables rot, then now is the time where bacteria or microorganisms start to invade! When food get ripe, spoilt, dented, scratched or bruished, the cells have been broken and it is susceptible to bacteria. That's why rotton, spoilt or even a dented canned food will harm our body.

Thus, microorganisms play only a part in rotting a fruit...the main thing which leads to the rotting of fruits is the ENTHYLENE GAS!
