Dear MEL
Topic Readers,
How
farmers put apples into suspended animation?
Do
you eat or buy apples only in fall when they are picked off the trees in the fall?
But apples are on the shelves almost all year around Why do apples stay fresh,
or not over-ripened so long? Where are they stored, and how?
You
may think temperature control does most part to keep the fruit from go
ripening. If that is the case, apples must have been stored in fridges somewhere.
But you also know that you can keep apples, or any other fruits, fresh only for
a week or a few weeks in the fridge. So how are those apples on the shelves have
been kept “fresh”?
In
fact, atmosphere and chemicals do a lot to control the ripening process. One
method that has been used to keep the fruit fresh is to reduce the oxygen in
the air, which is essential for ripening reaction, from the normal 20% level
down to a few percent level. Another way is to use a molecule to block the
access of the hormone.
Simple enough?
Enjoy
reading and learning what makes you enjoy eating apples all year round.
