1. FOOD PRESERVATION
By SARTHAK SINGH

2. FOOD PRESERVATION
Food preservation is the
process of treating and
handling food to stop or
slow down food spoilage,
loss of quality, edibility, or
nutritional value and thus
allow for longer food
storage.

3. METHODS OF FOOD
PRESERVATION

4. CANNING
 Canning is a good way to preserve things that
have been cooked. For example, people like to
stew tomatoes and then can them. They then
use them instead of canned tomatoes when
making things like pasta sauce and soups.
Other common things to can include
vegetables like corn, peas, and beets as well as
pickled vegetables, jams, and preserves. The
Ball Complete Book of Home Preserving is a
great resource for the beginner!

5. FREEZING
 There is an art to freezing things effectively. You
may can things like meat, cheese, fruit, and
vegetables. Plus, there are varying methods. For
example, some people claim that you should
blanch the vegetable in boiling water (with or
without sauce) before placing in the proper
packaging. Others say you don’t need to do that.
The proper container also makes a big difference.

6. DRYING
 Drying is when you take something and dry it out
under favourable conditions. This includes things
like herbs, prepared foods like beef jerky, and fruit.
For example, dried apple rings can be quite tasty
and a way to extend the apple harvests a little
further. However, you can dry pretty much any type
of fruit. The Excalibur Food Dehydrator handles all of
this with ease. Drying is when you take something

7.  VACUUM PACKING
 This is also another good way to
preserve things so that they stay extra
fresh. You can vacuum pack things like
prepared foods, dried meat or jerky,
and freshly milled flower. In fact, there
is very little that can’t benefit from
vacuum packing. Make sure you buy an
effective machine for it and follow the
package instructions. I really like the
Food Saver Vacuum Sealing System

8. SMOKING
 Smoking your food is another great example of a
food preservation method. One of the greatest
benefits is that it can help you extend the shelf
life of many meats. Not only that, but it tastes
delicious. Smoked salmon, for example, is
considered a delicacy.
 Once you start using a smoker, you will notice a
huge difference in the way your meat tastes.
Besides, this is one of the most popular ways to
serve bacon. If you raise pigs, for example, this is
a particular thing to consider, especially if you
really love the flavour.
