Look at your refrigerator. It may be full of the
leftovers of vegetables, fruits, meats, fishes and
foods. Some of them will give you off a terrible
smell and be thrown into a wastebasket soon. Moreover,
there are, although you may not be able to see,
a lot of bacteria deteriorating other stuffs in
the refrigerator as well as injuring your health.
It would be perfect if you always buy or cook
food as much as you eat for one meal. But you
may agree that it is actually impossible. If so,
what are you able to do? What if you are able
to do vacuum sealing as most restaurants are doing
this way for keeping their foods fresh long as
much as possible. In a vacuum, the deterioration
of foods gets retarded as the foods are not oxidized
and not exposed to bacteria.
