We actually use both refrigerators and freezers for food storage, but they serve different purposes due to their unique temperature settings and functionalities.
Refrigerators:
Temperature: Refrigerators maintain temperatures above the freezing point, typically around 35 to 40 degrees Fahrenheit (1.6 to 4.4 degrees Celsius). This temperature range is ideal for slowing down bacterial growth and preserving the freshness of perishable food items like fruits, vegetables, dairy products, and cooked meals.
Freshness: Refrigeration helps slow down enzymatic reactions and microbial spoilage, which extends the shelf life of food. This means that items like milk, cheese, vegetables, and leftovers can be kept for a few days to a couple of weeks, depending on the type of food.
Short-term storage: Refrigerators are designed for short-term storage, making it convenient for everyday use and allowing easy access to frequently consumed items.
Freezers:
Temperature: Freezers maintain temperatures below the freezing point, usually around 0 degrees Fahrenheit (-18 degrees Celsius) or lower. This extreme cold halts the growth of bacteria, yeasts, and molds entirely, preventing food spoilage.
Long-term storage: Freezers are excellent for long-term food storage, as freezing drastically reduces the rate of food degradation. Foods can be stored for months to even years, depending on the type of food and the quality of the packaging.
Food preservation: Freezing is especially useful for preserving raw meats, fish, bread, and many other items that can't be kept fresh for extended periods in a refrigerator.
In summary, refrigerators are primarily used for short-term storage of perishable items, while freezers are employed for long-term storage and preserving items for extended periods. By having both appliances, we can manage our food storage efficiently, ensuring we have fresh food readily available and reducing waste by preserving excess food in the freezer.
