I'm @mehwish-almas from Pakistan. Here I'm to present an interesting topic known as Food Preservation for a contest held by @sahmie. The contest title is preserve food ,preserve life.

When we take a look over human history, we can figure out that food preservation is dated in prehistoric times. This is a basic technique to save food from being spoiled. Most food items grow or cook are meant to be for short-term use.

And the cause of food spoilage is microorganisms present in our food. These microorganisms such as bacteria and fungi grow in food and change the taste and other characteristics of food, e.g., mould on bread.

Food preservation is a process in which different techniques are used to elongate the duration of food consumption without spoiling it. Through these techniques, microbial activity reduces to a great deal or stops under specific conditions. Food quality is maintained and it is edible for months or even years. Its taste, smell, colour and texture remain as of fresh one or at least near to it. Techniques which are used for food preservation are chosen carefully so that it does not damage ingredients and nutritional value of food.

🍎Prevention From Waste
Food preservation is very beneficial for humans to fulfill intake needs. Food preservation is most important for prevention of food waste. Food items come in excess seasonally. A great percentage of it is consumed but a lot is still wasted, like fruit veggies. Preservation of this wasted food may help to deal with hunger in areas like Congo, Syria and Sahel etc. Many land pieces are unable to cultivate food. So preserved food is a life line for these areas. Such lands may be some sort of dessert, mountain areas with long winter and snow falls.

🍎Food Preservation is Economical
Food preservation is one of the best methods for controlling the use of food resources. Avoid spoiling of food makes it possible to best use of resources according to desired conditions. Controlled use of food resources helps to maintain the cost of food because waste of food is always expensive.

🍎Availability of Unseasoned Food
Preserved food is a way to get unseasoned items to add variety and values to our meals. Preservation helps to maintain nutrition in food so we can have access to these things without trouble of availability.

🍄SALTING
Addition of table salt to food helps to elongate the time period of food usage by stopping the microorganisms activity to spoil it.

The chemical formula of table salt is NaCl or i.e Sodium chloride. I used table salt in preservation of Masala which includes onion,garlic,red chilies,and a lot of salt.

🍄 FREEZING
Freezing is the most suitable method for preservation to maintain taste. Many food items like meat tomatoes can be easily frozen and used when needed. I used to freeze these two items. Many other fruits and vegetables can be frozen for elongated use.

🍄USE OF EXCESS OIL
Excess oil is used for food preservation. This is also used for pickles.

In this condition salt is not used in excess. And pickle dipped in mustered oil ,so microbes not found any oxygen for their activity.And food is preserved.

🍄 DRYING
Drying is a common method used for centuries. I used this method for the preservation of chillies. Green chillies can be dried in shade until all of the moisture is evaporated and then grind them into fine powder.

This method can also be used for preservation of meat coriander and many other.

🍄 DEHYDRATION
Dehydration is a pro level of drying method. In this method, the food item which needs to be preserved is kept in the oven, so every bit of water goes off. Like cake rusk can be preserved through dehydration.

Here I'm finishing my blog . Hopefully you enjoy reading. Now I like to invite @shahid76 @mubasherali and @salmarani1994 to participate in this contest.
