Food preservation () is the fundamental process of treating and handling food to stop or greatly slow down spoilage, ensuring safety and quality over time . Since the dawn of civilization, humans have sought ways to store surplus harvests to survive lean seasons, leading to the development of methods that range from ancient sun-drying to modern high-tech sterilization. The Core Objectives of Preservation
The primary goal of any preservation method is to inhibit the growth of microorganisms—such as bacteria, yeasts, and molds—and to stop the activity of enzymes that cause food to decay. By controlling environmental factors like moisture, temperature, and acidity, we can prevent foodborne illnesses and reduce global food waste. Traditional Methods: Nature and Chemistry
