Refrigerator and Food hygiene: Basic Guidelines

Our main purpose in using a refrigerator is to keep food fresh as we store food in it for having it later. A refrigerator reduces the activity of bacteria in food, allowing it to stay fresh for longer. To get fresh and hygienic food, we need to keep our refrigerator clean as well. Normally we buy a refrigerator and use it for a long time without thinking of cleaning it. Sometimes we clean it occasionally which impacts the results of its application. This is where the question of cleanliness comes about in the refrigerator.

We the users are wise to choose a smart refrigerator according to the budget but fail to maintain refrigerator cleanliness. Some of us are unaware of the necessary standards for refrigerator cleanliness, while others are unaware of the importance of doing so. Ultimately the performance of the refrigerator decreases, or some functions get damaged as well. This is why it is important to deliver proper information to refrigerator users to encourage them to keep their refrigerators clean.

What is a Refrigerator and how it works?

A refrigerator is a device or compartment that artificially keeps food and drinks cool for a longer period.

It has 3 basic functions to work, these are-

1. Compressor,

2. Condenser,

3. Evaporator.

Refrigerators function by converting the liquid refrigerant circulating inside them to gas. This process, known as evaporation, cools the space around it and creates the desired effect. The pressure on the refrigerant must be decreased through an exit called the capillary tube.

To keep a refrigerator running, you need to get the gaseous refrigerant back to its liquid state. This is where the compressor comes in; it's similar to that of a bike pump for cycling. The compressor provides the same effect as that of an electric bicycle pump.

After the compressor has done its work, the gas should be under high pressure and hot. When the gas cools off inside the condenser, it changes back into a liquid in the refrigerator. The process is then cooled by the ambient air around the fridge.

Then, the liquid refrigerant circulates back to the evaporator where the process starts all over again.

Importance of Maintaining the Cleanliness of a Refrigerator

1. Prevent Food-Borne Bacteria

If the multi-air system is affected by any chance, the cooling compartment does not get the same temperature. By which the food stored in the corner may grow food bacteria. Also, food odor may spread unpleasantly. However, there are some refrigerators that have advanced features to keep foods hygienic and odor-free. For example, the LG No Frost Refrigerators have Hygiene Fresh Plus which is powerful enough to reduce odors and germs inside the fridge and maintain food sanity. 

The very first reason to maintain the cleanliness of a refrigerator is to prevent food-borne illness, because of low maintenance the cooler system of a refrigerator gets damaged which fails to maintain the required temperature to keep food fresh. If the multi-air system is affected by any chance, the cooling compartment does not get the same temperature. 

2. Lack of Cleanliness Decreases Performance

Rough use of any device impacts negatively and it goes for the refrigerator as well. If a refrigerator is left without cleaning it for a long period, it starts to show common problems like smell problems, cooling problems, water leaking problems, door lock problems, etc. This is why maintaining cleanliness in a refrigerator is necessary.

3. Cleanliness Increases Sustainability

Cleanliness is a major part of the maintenance of any device especially for refrigerators. And good Maintenance of any product increases its Sustainability. If we buy a refrigerator and leave it without taking care of it, the product will lose its sustainability in a faster way. If we regularly overload the refrigerator, do not clean it, and store rotten food with an unpleasant smell, it will not last long. It is important to enjoy fresh and healthy food.

4. Clean Refrigerator Ensures Proper Sanitation

We use a refrigerator to keep food fresh. A clean refrigerator easily ensures that in comparison to an unclean refrigerator. An unclean refrigerator makes the food unsafe to eat rather than keeping it fresh. The sanitation provided by a clean refrigerator is a no match with the sanitation of an unclean refrigerator.

Basic Rules and Steps for Maintaining the Cleanliness of a Refrigerator

No matter which brand or model we use there are basic 2 rules to maintain a clean refrigerator
