2. Definition
Salting is a sub category of the
drying method. The main difference
here is that salt is added to
products, mainly meat and fish, to
draw out moisture. This lowers the
bacteria content and makes food
adaptable for later use. Adding salt
to animal protein turns it into a bit
leathery.
3. Definition
It is used because most bacteria,
fungi and other potentially
pathogenic organisms can’t survive
in a highly salty environment, due to
the hypertonic nature of salt. Any
living cell in such an environment will
become dehydrated through
osmosis and die.
4. Definition
While today salting meat as a
method of preservation is
generally only commonly used in
such things as salted pork and
the like, salt has been used as
the primary method of preserving
meats and various other foods as
far back as history records.
5. Definition
Salted meat was often as well, by
exposing it to smoke from a wood
fire. In the American colonies, most
home properties included a
smokehouse where meats were
smoked and stored. The practice of
preserving meat with salt was so
common in the 1700s that most
people ate salted meat every meal.
6. Examples of meat using salt
as a preservative:
• tocino, hotdog, sausages, longanisa, chorizo, burger
patties, ham, salami, chicken nuggets, viennas, meat
loaf, liver pate, corned beef, blood sausage, meat
floss, bacon, etc.
7. Salt preserves food on the
following ways:
1.Salt dries food
Salt draws water out of food and
dehydrates it. All living things
require water and can’t grow in the
absence of water. Salt is used to
preserve beef jerky by keeping it
dry, and it prevents butter from
spoiling by drawing water out,
leaving just the fat.
8. 2. Salt kills microbes
High salt is toxic to most microbes
because of the effect of osmolarity, or
even water pressure. In very high salt
solutions, many microbes will rupture due
to the difference in pressure. In very
high salt solutions, many microbes,
affecting DNA and enzymes. Solutions
high in sugar also have the some effects
on microbes, which is why it’s used as a
preservative of foods such as jams and
jellies.
