Have you ever wondered? How fruits are able to hold out against many days or even weeks of being transported from different countries all over the world, but they only last 2-3 days in your house?
1. They are harvested early
They
are harvested before reaching ripening time, they are then quarantined; that is
put in rooms that are filled with gas. This is often storing them in nitrogen
gas which extends the shelf life of some fruits like apples when stored at the
right temperature. Maintaining such a sterile environment restrains the growth
of aerobic spoiling organisms
Why
not oxygen but nitrogen gas?
Yeah,
what most people don't realize about oxygen is that, it is liable to change rapidly
and unpredictably, especially for the worse. Oxygen degrades all kinds of
materials.
2.
Temperature
Just
like your deep freezer in your house, fruits are kept cold and not frozen as
the formation of crystals of ice can destroy plant state.
Lower
temperatures slow the activities of fungi or bacteria that cause chemical
reactions in fruits that make the fruits go bad.
3.
Humidity
A
lot of living organisms rely on water to live, and lowering humidity either by
refrigeration or direct removal of water from the surrounding air prevents
fungal and bacterial growth.
4.Genetic modification
The
natural composition of fruits themselves affects how long they take to ripen
and how long it takes for them to become overripe. For example, fruits with the
genes for reduced ripening hormone production can be selected so their produce
ripens slowly. Human beings can artificially interfere with these hormones to
either slow or increase how fast they last.
CLOSING
In
the nutshell all food items should be stored in right way so as to maintain
their inherent conditions.
