Old methods of food preservation include drying, where food is dehydrated to inhibit bacterial growth; salting, which draws out moisture and creates a hostile environment for bacteria; and smoking, which infuses food with antimicrobial smoke. Additionally, fermentation uses beneficial bacteria or yeast to convert sugars into alcohol or acids, preserving the food. Pickling involves soaking food in vinegar or brine, and canning seals food in airtight containers after heating to kill harmful microorganisms.
