Refrigerators are almost part and parcel of every home today. So invaluable is the refrigerator that some publications crown it as the greatest invention in the history of food. Considering all the inventions surrounding food, it is truly remarkable to single the refrigerator as the greatest. The proclamation begs the question, what makes refrigerators so special?
Historic Food Storage Methods
The refrigerator did not introduce food storage to human beings. Human beings were storing food for hundreds of years before the refrigerator’s invention. Motivated by a need to preserve the harvest for winter months, food preservation was a critical key to ensuring the survival of prehistoric humans. Additionally, prehistoric humans needed the means to preserve leftover food to reduce wastage.
While pre-historic methods were not as sophisticated as the modern ones, they went a long way to assist the people of the day to preserve food. Surprisingly, these methods also became the foundation of modern food preservation methods.
Some of the traditional food preservation methods that formed the foundation for modern methods are sun-drying and immersing of food in ice. Depending on the climatic conditions, one of the methods was popular among most prehistoric humans.
Modern Food Storage Methods
There are a variety of food storage methods in the market today because of technological advances. Consequently, you are no longer limited to the food storage methods suited to your environment. Now, there is pasteurization, vacuum drying, freezing, and freeze-drying to name but a few. Furthermore, new food preservation methods are constantly invented.
Benefits of Food Preserving Food
Effective food preservation methods are more critical today than in the past. The world order is such that some countries produce agricultural products and some process those products. For the successful transportation of agricultural products, they need to be stored properly.
Poorly stored food poses a health hazard to humans. Harmful bacteria can contaminate food and cause food poisoning.
Properly stored food retains its nutritional value, and so is more beneficial to humans. Consequently, properly stored food is almost as good as farm to fork food.
Refrigerators and Food Storage
A refrigerator is an appliance that stores food under cool temperatures. The appliance builds heavily on the food preservation of prehistoric times, where food was stored under ice or snow. While the name refrigerator dates back to the 1800s, the refrigerator as known today, was invented in the 20th century.
Since its invention, the refrigerator has undergone many transformations. Initially, refrigerators bore similarities to the ancient food storage model as they used natural ice to chill food. However, the growing demand for natural ice led to a shortage of pure ice to the chagrin of consumers. The contaminated ice would contaminate food leading to serious illnesses.
Due to the health risks involved, refrigerators became shunned food storage tools. However, necessity is the mother of invention. Since refrigerators had irreproducible benefits, scientists searched far and wide for ways to save the invention. This is how the mechanical way of produce ice was invented, the saving grace the refrigerator needed. It has been onward for the refrigerator since.
Why Cold Conditions Effectively Preserve Food?
The crux of refrigerators is that they keep food in cool conditions. To understand why refrigerators effectively preserve food, you need to understand the common causes of food spoilage.
The main causes of food spoilage are bacteria and fungi. Human beings cannot ingest spoiled food. Some of the signs of spoiled food are unpleasant smell, undesirable appearance, and/or an undesirable taste.
Bacteria are invisible food spoilage agents. Bacteria contaminate food by releasing toxins into it. The food develops an off-putting smell and taste. By sight, it may not be easy to recognize food contaminated by bacteria. This makes bacteria tenfold more dangerous than fungi.
Fungi are also food spoilage agents. The difference between fungi and bacteria is that fungi tend to change the appearance of food. Fungi-contaminated food is, therefore, is easily detectable. This easy recognition is fortunate because fungi-contaminated food can lead to death.
Different temperature conditions are favorable to different types of bacteria. Some bacteria thrive in cold conditions while others in warm ones. For proper food preservation, it is important to know the temperature range of harmful bacteria.
It is, however, conventionally accepted that most microorganisms struggle to survive in cold temperatures. Cold temperatures, therefore, reduce the likelihood of food contamination. Because they keep food in cold conditions, refrigerators are a good food preservation tool.
How Long Does It Take For a Refrigerator to Get Cold?
There are many refrigerator brands in the market. While all refrigerators have a similar goal, they accomplish it differently. Refrigerators come in a variety of colors, sizes, styles and with different features. The wide range of refrigerator choices makes it easy to find the right refrigerator for you.
Some refrigerators have double doors, such as the Samsung’s Family Hub Refrigerator, while some have single doors such as LG Bottom Freezer Refrigerator.
You can also find smart refrigerators that can connect to your phone. Through the connection, you can place reminders on the refrigerator, play music, or watch a movie. One amazing smart refrigerator that we recommend is LG InstaView ThinQ.
The size of a refrigerator determines the time it takes to cool down. The larger the refrigerator, the longer it takes. Typically, this time is anywhere between 3 and 48 hours for a new refrigerator. If you are looking for a top-quality refrigerator, we recommend Whirlpool WRV986FDEM WRV986FDEM 25.8 Cu. Ft. Stainless 5 Door French Door Refrigerator. It is advisable to go for GE GNE25JMKES French Door Refrigerator if you are on a tight budget, but you still want good quality.
Refrigerators are amazing food storage appliances. Refrigerators are a modern take of the prehistoric food storage method of storing food under the ice.
Food storage is important because it helps retain the nutritional value of food and reduce the likelihood of food spoilage. There are many food storage methods in the world today. Cold temperatures reduce the possibility of food contamination. Refrigerators can take up to 48 hours to become cold. For the best value refrigerator, we recommend the Whirlpool 190 L 2 Star Direct-Cool Single Door Refrigerator.
