Examples of food preservation methods from the past.

📚 Quick Study Guide

• 🧊 Salting: 🧂 One of the oldest methods, salt draws out moisture from food, inhibiting bacterial growth.
• 💨 Smoking: 🔥 Exposes food to smoke from burning wood, which dries the food and deposits antimicrobial compounds.
• ☀️ Drying: 🌞 Removing moisture from food to prevent spoilage. Common examples include sun-drying fruits and vegetables.
• 🏺 Fermentation: 🦠 Uses beneficial microorganisms to convert carbohydrates into acids or alcohol, preserving the food and often enhancing its flavor. Think sauerkraut or kimchi!
• 🍯 Pickling: 🥒 Immersing food in an acidic solution, such as vinegar, to inhibit bacterial growth.
• 🌡️ Cooling: ❄️ Storing food at low temperatures slows down microbial activity. Historically, this involved using ice or cool cellars.
• 🫙 Sealing: 🔒 Creating airtight environments to prevent microorganisms from entering and spoiling food.
