Question

Food has been preserved using various methods since prehistoric times.

Make a list of four old methods of food preservation, which are still being used today.

Answer 1

1. Sun Drying: Removes moisture from food to inhibit the growth of microorganisms (e.g., dried fruits, vegetables).
2. Salting/Pickling: Preserves food by adding salt or acidic brine to prevent spoilage (e.g., pickles, salted fish).
3. Candying: Coats food, typically fruits, in sugar syrup for extended shelf life and sweetness (e.g., candied peel).
4. Roasting: Uses dry heat to preserve and enhance the flavor of food (e.g., roasted nuts, grains).
5. Baking: Cooks and preserves food by using prolonged dry heat (e.g., bread, biscuits).
6. Fermentation: Uses microorganisms to convert sugars into alcohol or acids, preserving food (e.g., yogurt, kimchi).
7. Smoking: Exposes food to smoke for flavor, preservation, and longer storage (e.g., smoked meats, fish).
