What is a commonly used method to prevent food spoilage?

Refrigeration is a commonly used method to prevent food spoilage because it slows down the growth of bacteria, yeasts, and molds that thrive at higher temperatures. By maintaining a lower temperature, typically at or below 40°F (4°C), refrigeration helps preserve the freshness and safety of perishable foods, such as dairy products, meats, fruits, and vegetables. It extends the shelf life of these items, allowing them to be consumed over a longer period without significant loss of quality or safety.

While other methods like freezing, canning, and dehydration are also effective in preventing spoilage, refrigeration is especially practical for everyday use in households and restaurants. It allows for easy access to a wide variety of fresh foods while minimizing waste. Each of these other methods has its own unique benefits and applications, but refrigeration is the most common and convenient method for managing food safety in everyday situations.
