What is Food Preservation?

Food Preservation means keeping food safe for a longer duration. This process slows the growth of germs and prevents food from spoiling quickly. There is a good example of it: milk gets sour if it is left out for hours; however, it is kept in the refrigerator, so it lasts longer. Similarly, vegetables can be dried or stored in a cool place.

Therefore, Navodaya Class 6 EVS Food Preservation helps students learn why food needs proper storage.

Why does food spoil?

Food gets rotten due to germs, moisture, heat, air, and insects. Therefore, this leads to the growth of fungi and bacteria on food. As a result, after it rots, the food's smell, texture, and color change. Another example of this is bread; once it is spoiled, it develops green or black patches. Fruits become soft and rotten. Likewise, cooked food smells bad after it is left out for a long time.

This leads to the emergence of proper storage, which is discussed in Navodaya Class 6 EVS Chapter 11 in detail. Therefore, it helps students understand the importance of food preservation.

Common Methods of Food Preservation

There are various methods of preserving food. Some ways may be old, while others use modern technology.

Drying: One of the oldest methods; here, the moisture is removed from the food. Many germs grow in moisture. Dry food stays for a longer period. For example, people dry chillies, fruits, vegetables, and grains in the sun. Therefore, drying is a simple and useful method.

Salting: The various types of foods that are preserved by putting salt in them. Pickles, fish, and some vegetables are often preserved with salt. Thus, salting has been used for many years.

Sugar: In the same way as salt, sugar helps preserve many foods; this slows the growth of germs. For example, jams, jellies, and some fruit products contain a good amount of sugar. As a result, they can stay fresh for a longer time when stored properly.

Refrigeration: Refrigeration implies storing the food item inside a refrigerator. The low temperature reduces the speed of growth of various germs. Milk, vegetables, fruits, cooked food, and other products can be stored in the refrigerator. Yet, even refrigerated food items cannot last indefinitely.

Pickling: Another popular process is that of pickling. Vegetables, fruits, and other food items can be preserved through pickling by the use of salt, oil, vinegar, or various other spices. For example, pickled lemons and pickled mangoes are quite popular in India. Hence, the pickling process is both useful and traditional.

Heating/Boiling: The heating and boiling processes help kill many of the harmful germs from the food. For example, milk is often boiled before consumption. Other food products can also be heated during their cooking.
Importance of Food Preservation
Food preservation has many benefits. First, it helps reduce food waste. Secondly, it allows us to store food for future use. Thirdly, it helps people enjoy some foods even when they are not in season. For example, mangoes are available mainly during summer. However, mango products such as pickles and jams can be stored and used later. Navodaya Class 6 EVS Food Preservation also helps students connect classroom learning with daily life. Therefore, this topic is useful for both studies and everyday activities.
