Introduction:

Have you ever wondered why your potato chips, flour, pickles, and tomato sauce can be stored in the house for days, weeks or months before we eat or use them and they do not get spoilt? Let's find out as we learn more on this.

Presentation:-

Step 1:- Meaning of farm produce preservation.

Farm produce preservation is the process of treating and keeping farm produce in a way that greatly shows down or stops spoilage. Preservation of farm produce is usually done when the farm produce are in season and abundant to make them available when they are out of season and expensive.

Step 2:- Benefits of preserving farm produce.

Farm produce are usually preserved for the following reasons:-

2. Preserving farm produce ensures that they are always available for future use even after their seasons.

3. Preserving farm produce makes them available in areas where they are not produced.

4. Preservation helps to retain the color, taste and nutritional value of farm produce.

5. It prevents possible contamination and infection from unpreserved food items.

6. It helps to keep farm produce for a long period of time without spoilage and wastage.

7. It helps to protect farm produce from insects and other pests attack.
