What is the primary function of a fridge in food storage?

The primary function of a refrigerator in food storage is to extend the shelf life of food. Refrigeration slows down the growth of bacteria, yeasts, and molds that can spoil food or cause foodborne illnesses. By maintaining a lower temperature, typically between 32°F to 40°F (0°C to 4°C), a fridge helps preserve the quality, texture, and nutrient content of perishable items like fruits, vegetables, dairy products, and meats.

The other options do not align with the primary function of a refrigerator. Cooking raw ingredients and serving hot meals are associated with stovetops and ovens, while preparing beverages may be accomplished through other methods like brewing or mixing, not primarily through refrigeration. Therefore, the effectiveness of a fridge in prolonging food freshness and safety is crucial for maintaining a healthy food supply.
