When it comes to food safety, refrigerator storage plays an important role because it enhances food safety and reduces food waste. It also contributes to consumer health by protecting food from contamination. 

This article will explore the best practices for refrigerated food storage. Learning about proper food refrigeration can be beneficial in day-to-day life, as it can provide health benefits and keep your food quality fresh for longer. With these tips, you can keep your food fresh, secure, and delicious for as long as possible.

Consequences of inadequate refrigeration

Inadequate refrigeration can lead to compromised food quality, resulting in food spoilage. Microorganisms that cause spoilage to grow at room temperature and through ineffective refrigeration temperatures.

You can observe them through food color, smell, or texture. Although food spoilage might not cause any severe sickness, the quality of food becomes bad to consume, among other things, such as the following:

Puts the elderly in a vulnerable position

According to a study conducted in 2020, older adults with low education who are unaware of safe refrigeration practices and the temperature settings of their fridges represent the most vulnerable category when it comes to food safety risks.

Inadequate refrigeration is likely to increase the risk of illnesses among the elderly. Therefore it becomes imperative to pay attention to practices and initiatives that mitigate the health risks due to compromised refrigeration practices. 

Impacts the economy in different ways

Inadequate refrigeration has an economic impact as the costs and emissions related to increased energy consumption due to refrigeration were estimated to be around £80.9 million (about USD 104 million) and 367,411 tonnes of carbon dioxide equivalent. 

Starting with lowering the refrigerator temperature from 7°C to 4°C could save a lot of money and reduce carbon emissions. This action could save £162.9 million (about USD 210 million) worth of wasted food each year, and prevent the release of 270,000 tonnes of carbon dioxide equivalent emissions. 

By including only certain food items that don’t need to be refrigerated and eliminating those that don’t benefit from it, the study found that you could save even more: up to £283.8 million (about USD 366 million) and 578,383 tonnes of carbon dioxide equivalent. By being and making mindful choices about refrigeration-related practices, you can reduce many of the negative consequences.

Environmental consequences of food waste

Food waste has detrimental effects on the environment, society, and economics. According to the Food and Agriculture Organization of the United Nations (FAO) report, one-third of the food that is intended to be consumed by people worldwide is wasted, which amounts to around 1.3 billion tonnes of wasted food a year. 

When the wasted food decomposes, it produces a harmful greenhouse gas that affects the environment. Ineffective utilization of food resources negatively impacts effective economic practices and can disrupt sustainable development.

When food is thrown out, all inputs utilized in its production, processing, transportation, preparation, and storage are likewise squandered. Proper refrigeration is crucial for food safety and in reducing the negative impacts of food waste.

How refrigeration prevents foodborne illnesses

Refrigeration is essential for food safety, as any food kept at favorable temperatures for bacterial growth is likely to get contaminated. Keeping food at low temperatures through refrigeration can slow down the growth and multiplication of microorganisms that cause spoilage and help extend food shelf life.

Unfavorable conditions for bacterial growth

Warm and humid places are the best for bacteria to grow and reproduce. You wouldn’t want your food to become the perfect breeding ground for bacteria. By placing food in the opposite environment, the conditions become unfavorable for bacteria, so refrigeration is an effective way to keep food fresh.

Optimal refrigeration temperature prevents contamination  

A study determined that to protect the food from microbial contamination after buying or cooking, keep it in the refrigerator at the earliest possible opportunity. Knowing the correct refrigeration temperatures is essential to protect the food from contamination. 

According to the FDA, the correct refrigeration temperature should be kept at 40°F or lower for the best possible results in preserving food.

Food hygiene and safety

Refrigeration is essential for food hygiene and safety and avoiding the spread of hazardous microorganisms. It helps guarantee that food is safe and of good quality by suppressing bacterial development and food degradation.

Best practices for refrigerated food storage

Following a few practical tips and guidelines is important to ensure proper food storage in the refrigerator. By incorporating the following best practices, you can improve the shelf life of your food and keep it fresh for a longer period in the refrigerator.

Organize the fridge

Keeping raw meat, poultry, and seafood separate from ready-to-eat foods is important to prevent cross-contamination. Use separate containers or sealed plastic bags to store these items. Keep fruits and vegetables in separate drawers/shelves to prevent them from getting too cold.

Maintain appropriate temperatures

The ideal temperature for a refrigerator is between 35°F (1.7°C) and 38°F (3.3°C). Household refrigeration appliances can help extend the shelf life of fresh food products by improving their storage conditions. 

The typical refrigerator temperature of 4°C is not ideal for many fresh products, so it’s important to ensure adequate storage conditions to reduce food spoilage and prevent quality losses such as loss of aromas or vitamins. By including multiple non-frozen food compartments like chillers (ranging from -1°C to +2°C) and a cellar (8-14°C), these appliances can substantially reduce food waste due to spoilage.

Use airtight containers

Storing food in airtight containers can help prevent spoilage and keep food fresh longer. Label the containers with the storage date to track how long the food has been in the fridge. Additionally, avoid storing food in open cans, as the metal can react with the food and cause it to spoil quickly.

In general, sustainability is trying to meet our own needs without jeopardizing future generations’ possibility to fulfill their requirements by not depleting the earth’s natural resources. 

Sustainability in terms of nutrition means producing food in a way that safeguards the environment, makes efficient use of natural resources, and improves the quality of life in food-producing communities, including people and animals. Food preservation can be one of the many practices that can be done at home to contribute to sustainability.

Food preservation has become necessary because individuals in households may have a preference for certain produce regardless of whether it is in or out of season. Food preservation allows for variety, reduces food waste, and increases food supply at any given time — making it an easy step to take toward sustainability. 

In this article, you will understand that sustainability practice does not necessarily mean having to make a big gesture, such as investing in an expensive solar panel. You can do it with a small step starting with you and your household. You can contribute by practicing food preservation at home; it is not as hard as you thought and is doable. This article will help you get started with food preservation at home while also enjoying the benefits of doing it.  

What is food preservation?

Food preservation can be defined as “the processes or techniques undertaken to maintain internal and external factors which may cause food spoilage.” It is the process of preparing and handling food to avoid spoilage and food-borne illnesses while preserving nutritional value, texture, and flavor. 

It prevents microorganisms in food from growing, surviving, and reproducing. You can use physical, chemical, biological, or combined methods to change the living environment of various microorganisms, attempting to prevent or eliminate their reproduction and growth.

Benefits of food preservation 

Food preservation has an important role in reducing food waste and helps to extend the shelf life of food.

Environmental impact

Preserving food minimizes the amount of food that spoils during peak production seasons, ultimately reducing food waste. You can keep food intact for longer periods by preserving it, allowing you to consume particular foods even during off-peak seasons. 

Nutritional value

Food preservation is advantageous because it preserves the nutritional value of food while also preventing spoilage. Furthermore, some foods that are preserved through fermentation not only have enhanced flavor but also have benefits on your health, such as promoting antimicrobial, anti-fungal, anti-inflammatory, and anti-atherosclerotic properties. 

How to do food preservation

Preservation can be done in a variety of ways and some of the methods only require equipment that is readily available in your home. 

Cooking

Cooking is one method of food preservation because heat can kill the microorganisms that cause food spoilage. Cooking also improves the flavor of food. For example, the flavor of Golden Noble apples is sour and unpleasant, but when the apples are stewed with sugar, their flavors are significantly improved.

Canning

Canning is a method of preserving food that involves processing fresh fruits and vegetables and then sealing them in airtight containers. There are two types of canning methods: 

1. Pressure canning which utilizes a pressure canner to preserve low-acid foods like meat and,
2. Boiling water bath canning which uses a regular canner to preserve high-acid foods like tomatoes.

Pickling

Pickling is primarily accomplished through a brining or marinating process. A pickle can be made by soaking the food in salt, a process known as fermentation, or by preserving it in acid, such as vinegar, for an unfermented pickle. Both of these processes flavor the pickled food while also producing good bacteria that inhibit the growth of harmful microbes. 

Dehydrating

Drying the food removes moisture and prevents bacteria, yeast, and mold from growing and spoiling it. By combining warm temperatures, low humidity, and air current, food can be dried in the sun, an oven, or a food dehydrator. As a result of the removal of moisture, the food shrinks and loses weight.

Salting/brining

Bacteria and other potentially harmful organisms that cause food spoilage can not survive in a food material with high content of salt, such as when salting or brining, because salt is hypertonic.  

Wet salting or pickling involves rubbing the food with salt before pouring brine over the packed salted meat. Wet salting is also known as wet brining. During this procedure, the food is immersed in a brine solution. To do wet brining, the food must be completely submerged in a large pot or bucket. Thus, it requires a lot of space in the fridge. However, wet salting or brining does not result in salty meat.

Dry salting is a method of removing water from food by sprinkling salt on it and leaving it in a cool, dry place. Dry salting is also known as dry brining. It still takes up valuable refrigerator shelf space, but you do not have to deal with a large bucket or container of salt water. However, dry salting produces more salty food compared to wet salting. If you want to infuse a stronger flavor, dry brining is more suitable. 

Freezing

Freezing is a preferred method of preservation in any household because it eliminates the need for additional equipment and utensils. Freezing slows the growth of microbes and enzymes that cause food spoilage. Freezing and frozen storage are excellent methods for preserving a food’s nutritional quality. Many foods begin to freeze at temperatures ranging from 0 to -5 degrees Celsius. However, it is recommended to freeze food at -18 degrees Celsius to ensure food safety. 

In conclusion

To sum up, food preservation is one of the many methods that can be done to contribute to the sustainability of food processing in a household. Food preservation can minimize food waste and also extend the shelf life of food. This practice is sustainable because, through preservation, individuals are consuming foods in a way that has the least environmental impact. Food preservation can be easily done at home and it is as simple as freezing and cooking, salting, pickling, or canning.
