8. Natural preservatives are the traditional preservatives that
stops or delays the growth of bacteria or microbes in the
food for a specific time period.
Some common methods of Natural Preservation:
 Preservation by Himalayan Sea Salt
 Preservation by Sugar
 Preservation by Garlic
 Preservation by Spicy Ingredients
 Preservation by Lemon

9. Preservation by
Himalayan Sea Salt
Salt has long been touted as one of
the best natural preservatives and
if it is Himalayan salt, it is even
better. Using just a pinch of
unprocessed Himalayan salt can help
preserve your food in a healthier
way. Use it in just about anything;
pasta dishes, soups, dressings,
dips, spreads and any vegetable
dishes.

10. Preservation by Sugar
Sugar is a natural preservative
that helps food get rid of water
and microorganisms. Sugar follows
the same science as salt that is
osmosis or dehydration. It soaks up
the water that may lead to the
growth of bacteria and further keep
the food well preserved for a
longer period.

11. Preservation by Garlic
Garlic has anti-viral properties
that help in fighting bacteria,
both in your body and food. Tossing
a clove of garlic or some minced
garlic in your soup, dressing, dip
or any other dish will help keep
harmful bacteria at bay and will
let the food stay fresh for longer.

12. Preservation by
Spicy Ingredients
Spicy ingredients like Cayenne,
mustard and hot sauce are some of the
best natural food preservatives.
Mustard and hot sauce have some
percentage of vinegar in it. Spicy
foods are known to fight bacteria from
attacking food and keep it fresh for
longer. Add a hint of cayenne in
desserts or smoothies to give a slight
touch of spiciness and of course to
preserve it for long.

13. Preservation by Lemon
Lemons are a natural source of
citric acid and make an
exceptionally good preservative.
Their peels and flesh are the best
fix to prevent your food from
spoiling. Squeeze them in your cold
dishes or on food right after they
are cooked.
