Meaning of Farm Produce Preservation

Farm produce preservation is the process of keeping farm produce in good condition for a longer period.

Reasons for Preservation

Farm produce is preserved to:

1. Prevent spoilage.
2. Reduce waste.
3. Make food available for a longer time.
4. Maintain quality.
5. Make produce available when it is out of season.

Sun-Drying

Sun-drying means removing water from farm produce by exposing it to sunlight. Examples include:

• maize
• pepper
• cassava chips
• vegetables

☀️ + 🌽 = dried maize

Smoking

Smoking involves exposing food to smoke and heat. Examples include:

• fish
• meat

🐟 → smoking → smoked fish

Frying

Frying involves cooking farm produce in hot oil. Examples include:

• plantain
• yam
• fish

Freezing

Freezing means keeping food at a very low temperature. Examples include:

• meat
• fish
• chicken

Freezing slows down spoilage.
