2. Food preservation refers to the process of extending
the shelf life of food by inhibiting the growth of
microorganisms like bacteria, fungi, or other spoilage
agents. This is typically achieved through various
techniques such as canning, freezing, drying, pickling, or
using preservatives to maintain food quality, safety, and
flavor over time.

Preserving food is essential for several reasons:
Reducing Waste: It helps prevent spoilage and extends the
shelf life of food, reducing waste and ensuring more efficient
use of resources.
Availability: Preserving food allows it to be available beyond
its natural season, ensuring a consistent food supply
throughout the year.
Food Security: It contributes to food security by ensuring
access to food even during times of scarcity or in regions
with limited agricultural production.

Extend food's shelf life
Reduce rotten food gas
Reduce dietary deficiencies
food preservation has numerous benefits:
Extended Shelf Life: Preserves food, reducing waste by
keeping it fresh for longer periods.
Nutritional Retention: Helps maintain essential nutrients,
vitamins, and minerals in preserved foods.
Convenience: Ready-to-use or quick-prep preserved foods
save time and effort in meal preparation.

9. • Clean the foods that are going to be preserved
• Make sure there is no mold, bad
bacteria, or any other substances that
could interfere with the preservation
process
• Preserve the food using your desired method
• Keep it in sealed packaging before storing it
Selection: Choose fresh, high-quality produce or ingredients.
Cleaning: Thoroughly wash to remove dirt and contaminants.
Preparation: Cut, trim, or blanch as needed for the chosen
