Unfortunately, the most recent and reliable research suggests that one third of the world's annual food production ends up in the garbage. Translated into the most imaginable quantitative terms, this is 1.3 billion tons of food that is wasted every year. That is, the equivalent to feed 868 million people in the world, and 4 times the amount of food that is needed to lead a satisfying life!
The introductory data helps us to understand that food waste is a problem whose resolution can no longer be postponed, and it is no coincidence that the United Nations has indicated it as the number 2 theme of their sustainable development goals 2030.
But why is food so wasted? And what can we do to be able to run for cover?
In truth, there are many reasons why so much food is wasted globally. Sometimes, we simply buy too much food and fail to consume all the food before it spoils.
Other times, some foods don't meet our… aesthetic standards. Aesthetically unappealing fruits and vegetables make up a third of all wasted food - even if those foods are perfectly good to eat.
In other cases, the food simply doesn't stand a chance because of one storage improper. And that's a shame, because properly storing food can slow down the aging process and help reduce food waste.
How to store food
Fortunately, there is something we can do to improve the conservation of food stocks. And now that we know that careless storage of food may be able to spoil food at a very fast rate, we believe it is time to look at the best practical examples to take action!
Many people, for example, do not know that the so-called “Freezer burn” is what contributes to burning the foods in the freezer the most. It is a condition that occurs when water molecules escape from frozen food and oxygen molecules infiltrate it. The oxygen molecules can dull the color and change the flavor of the frozen product, perhaps making it unattractive.
Mind you, most frozen foods that undergo this alteration are still safe to eat, but because many people find the texture and flavor unsatisfactory, the food ends up in the trash anyway.
Use the bags
Fortunately, there are many things we can do to extend the life of foods and optimize their storage in the freezer.
One tip is for example to use sealable storage bags. Simply store the products in specially made plastic bags, thus extending the shelf life of the food and reducing the risk of cross-contamination. Just buy bags with sturdy seals or double zips and make sure the bag closes well, without being too difficult to open.
A second suggestion, always in the same "sector", is to use vacuum storage bags. These airtight bags effectively help to store foods such as red meat, poultry, fish and cheese. These bags in fact help create an oxygen and moisture barrier, effectively helping your goods stay fresher for longer.
Other solutions to preserve food for a long time
Between others solutions to better preserve food supplies then there are i special containers for food storage. These are plastic or glass containers of various sizes, which are used to store and, in some cases, heat food. Not only do they help extend the life span of the foods it contains, but they also facilitate the organization and effective use of space.
Of course, if you have the opportunity you can also opt for the new smart refrigerators, which are equipped with devices that can concretely extend the life of the food stored in the various shelves.
In conclusion, store food effectively it is a real moral obligation, as well as a particularly important form of saving.
You can begin to approach this approach with proper food packaging and the correct position in the fridge. For example, pre-prepared foods (such as salads, cakes and other ready-to-eat products) must be stored on top of the refrigerator. So, from top to bottom, it is possible to store the goods in the following order: raw products, raw seafood, raw red meat, raw minced meat and then raw poultry. The use of this separation method reduces the risk of accidental spills or leaks that cause food contamination.
Of course, don't lose sight of the fact that different foods have different optimal storage temperatures. Not knowing the correct temperature at which your food should be stored can cause it to spoil quickly and become harmful to consume.
Finally, remember that refrigerators, freezers and pantries - that is, any areas where food is stored - must be cleaned regularly. Daily surface cleaning and weekly deep cleaning are recommended for the refrigerator, and monthly cleaning for dry storage areas.
