Understanding Refrigerator Functionality
Refrigerators play a crucial role in preserving food by slowing down the metabolic processes of fruits, vegetables, meats, and dairy products. When fresh produce is harvested, it continues to respire, and refrigeration reduces the speed of this process, effectively extending its shelf life. Similarly, refrigeration inhibits the growth of bacteria and fungi, thus preventing spoilage and allowing items like milk to remain fresh for a longer period. This function of slowing down time for food is fundamental to the modern food system and demonstrates the refrigerator's importance in food safety.
