Food Preservation

Food preservation keeps food fresh longer by preventing spoilage caused by bacteria, fungi, and other microorganisms. Different methods work in different ways to achieve this goal. Smoking involves exposing food to smoke from burning wood, which kills harmful organisms and adds flavor—think of how smoked fish is popular in Nigerian coastal communities. Drying and dehydration remove water that microorganisms need to survive, making foods like dried beans and locust beans last for months. Freezing and refrigeration slow down bacterial growth by lowering temperature. Adding chemicals like salt, sugar, or vinegar creates an environment where bacteria cannot survive; this is why Nigerian pepper soups stay preserved in bottles. Canning and bottling seal food in airtight containers to prevent contamination. Each method protects your health by reducing food poisoning risks.
