Food and water are two essential things that are needed to keep human beings alive. They are as vital to us as fuel is to cars and electricity is to light up bulbs. Men from a very early age have been wandering around the earth, living and reproducing and acquiring all the very best knowledge they possibly can. Side by side, they have been gathering information and ways to improve and improvise their lives. Obviously, food is our primary need, so we are bound to keep it in reserve not only for us but also for the people around us.
The very first preservation of food is known to be done perhaps centuries ago, where men used natural ways of preserving food through their knowledge using vinegar, onions, and basic methods. From that time and up to know what has changed is perhaps the quantity of the food being preserved. Also, with the advancement in science, they discovered many new ways to keep food protected for more extended periods. So far, the fundamental method of preserving food that we all know is by keeping it in a refrigerator, which also takes up a lot of energy to be maintained. Most of the businesses on B2BInspection, that supply food products around the world rely on this. The underlying problem apart from it consuming energy is that you can store a certain amount of food at a time. The capacity gets filled.
Basic and Old School Methods to Preserve Food
Before the refrigerator ever existed, three very basic methods of keeping food preservations were used, which included drying, oiling, and Lacto-fermentation.
- Drying is an old aged method yet very useful up till now. By this method, you can preserve fruits, vegetables, and even meat. It does not really affect the nutritional value; perhaps it does maintain it. Apart from that, it has known to make food incredibly light, which makes it easier to be carried and transported. Dehydrators are possibly used even to dry food at places, and it is cost-effective in anyways then the refrigerator.
- Preservation of food in oil is another ancient method. The durability of food depends upon how well you pack the food. The quality and quantity of oil also used matters. Oil delays deterioration, oxidation, and prevents food from the mound. Oils, especially like the one abstracted from olives, are well known for this purpose, and it also adds essential fat to the food product. Tomatoes, cheese, and many food items can be stored this way, and people do still use it, especially when they are in plans to store food in summers so they can use it in winters.
- Lacto-fermentation, in other words, known as pickling, not only preserves the nutritional value of the food, but it also enhances food quality. Observant has found to know that after storing food by such a method, the food becomes more vibrant, the flavor enhances, and it feels more delicious. This is one of the cheapest yet trickiest ways, but an individual should spend time learning such skills as it is valuable.
Other Methods and Why One Should Use Them
Preserving of food in waters and alcohols, smoking, boiling, or even using chemical preservatives are few of the many methods used in the world. I believe with so many different nations, there are so many different home remedies that are used. In some places, people burry food under the soil while some create basic refrigerators by clay that doesn’t need any electricity and are cooled because of how clay acts against evaporating water which is continually dropping on top of it. These methods may require efforts and are, at times, more time consuming, but they have always been proved to work and are mostly healthy for the consumers. Not all, but some of them can be recycled and can be used multiple times.
You can’t carry refrigerators everywhere, but they can be used even if you are traveling. Jars, bottles, and even small cans can be taken easily without any hustles.
