2. What Is Food Preservation?
Food preservation is the process of treating
and handling food in such a way as to stop or
greatly slow down spoilage to prevent food
from getting spoilt. This can be done in a
number of ways, you can coat a food in a
substance that will preserve it such as salt,
sugar of vinegar. you can dry food or you can
keep it in an environment that makes bacteria
that degrades food less able to survive such as
a fridge or freezer.
3. Food preservation is the science of
extending the shelf life of food while
maintaining as much as possible of its
nutritional quality and avoiding the
growth of unwanted micro-organisms.
Food preservation has been practiced in
a variety of ways for hundreds of years.
4. There are a number of different ways of
preserving foods. Some involve storage
methods, some involve packaging, and
some involve treating the food in
particular ways prior to or during storage,
either cooking it in whole or part or
combining it with other foods or
substances.
5. Chilling food is one way of maintaining it.
Some foods do well with the cool level
that we associate with refrigeration,
while other food items are best kept
frozen. Cold cellars or root cellars were
historically used to keep produce, and
they are still used today.
