Food Preservation

Food preservation is essential for preventing spoilage and extending shelf life.
Preserved foods are often more delicious and have high consumer demand.

Methods of Food Preservation

Drying
- The oldest food preservation method, dating back to ancient Egyptians.
- Involves removing moisture from food to inhibit spoilage.
- Two techniques:
  - Natural Drying: Utilizes sunlight for moisture removal.
  - Artificial Drying: Employs equipment for controlled drying conditions.
Freezing
- Involves lowering the temperature to freeze food, turning it into a solid state.
- Effectively stops bacterial growth and preserves nutrients.
Salting
- Salt acts as a preservative by drawing moisture out and creating an inhospitable environment for microbes.
- Commonly used for preserving poultry and meats.
- Two types of salting:
  - Dry Salting: Applying salt directly to food without water.
  - Wet Salting: Using a brine solution (saltwater) to preserve food.

Benefits of Food Preservation

Extends the shelf life of food products.
Reduces food waste by prolonging usability.
Maintains nutritional quality of food items over time.
Enhances flavors and textures, often leading to improved taste.
