1. Canning: Seals food in airtight containers for long shelf life. 2. Freezing: Preserves by slowing down enzyme activity which causes spoilage. 3. Drying: Removes moisture to prevent microbial growth, extending shelf life. 4. Fermentation: Uses beneficial bacteria to preserve food and enhance flavor, seen in yogurt and sauerkraut. 5. Pasteurization: Involves heating to kill harmful microbes, commonly used in milk and juices.**

FAQs & Answers

  1. What is food processing? Food processing involves techniques that help preserve food, enhance flavor, and improve safety by controlling spoilage and contamination.
  2. How does fermentation preserve food? Fermentation uses beneficial bacteria to produce acids and other compounds that inhibit harmful microbes, preserving food and adding unique flavors.
  3. Why is pasteurization important in food safety? Pasteurization involves heating food or beverages to kill harmful microbes, reducing the risk of foodborne illnesses.
  4. What are the benefits of drying food? Drying removes moisture from food, preventing microbial growth and extending shelf life while reducing storage space.
