Food preservation techniques

Food preservation techniques help extend the shelf life of food and prevent spoilage. Common methods include refrigeration, which slows down bacteria growth; freezing, which stops it entirely; and canning, which seals food in jars to prevent air and bacteria from entering. Drying removes moisture, making it harder for microbes to thrive, while pickling uses vinegar or salt to inhibit growth. Fermentation leverages beneficial bacteria to enhance flavors and preserve. Each technique has its advantages and uses, ensuring food remains safe and flavorful for longer periods.
