Hello all, I hope you all are safe and healthy during this lockdown period. In the present situation, there has been a rise in problems in maintaining safe and nutritious food supplies all around the world. Thereby it is crucial to possess knowledge on processing and preserving of foods so that we can increase their shelf life and help in maintaining a minimal loss of nutritional value. Generally, foods spoil quickly and will only last long if they are canned, dried or preserved under suitable conditions.


Here are a few food preservation methods that can be used at home during this pandemic.

1) Canning:

In the canning method, the food spoiling bacteria are killed by heating the food with the help of a boiling water bath or pressure canner. In this method, as the food is sealed in an airtight container, the bacteria can't enter the vessel due to which the food can be preserved for a long time. Foods that can be canned include vegetables, meat, dairy products, etc. which provides nutrients to boost our immunity during this COVID-19 pandemic.

2) Freezing:

In this method, the food is exposed to cold temperatures with the help of a freezer. Frozen food can't be stored for a long period as freezing doesn't kill the bacteria, it only renders it inactive.


3) Pickling:

Pickles can be made from salt, oil or vinegar. These ingredients help in inhibiting the growth of bacteria. In India, lemons and mangoes are commonly used.

4) Smoking:

Smoking is one of the most widely used methods for preserving meat which is a rich source of protein. This method is usually carried out by placing the meat over the grill to receive smoke and steam.

It is a method in which heat is used in the absence of oil and water.
