One may be tempted to ask, what is food preservation?
Anyway, for the benefit of those who may not actually understand the concept, it is simply the prevention of growth of fungi, bacteria or any other micro organism.
It also involves slowing the oxidation of fats that is responsible for rancidity.
But whether you believe it or not, it is very possible to preserve your food without refrigeration.
Do not forget that long before the design and manufacture of freezers and coolers, food preservation and storage issues have been sorted out but unfortunately, modern day people have abandoned this knowledge for “Quick and easy” solutions.
However, it is possible to preserve food all year round without a refrigerator as we can see below.
This is one of the traditional methods of food preservation without refrigeration.
It involves cooking food, sealing it inside a jar or sterile can, boiling the container so as to weaken the entire remaining bacteria until you are just ready to eat.
Food preserved with this method can be eaten right away. It is important to note that food preservation via canning requires multiple stages of work.
For example, you have to prepare the food and any additive such as sugar syrup or brine, sterilization of the lids and glass jar, filling, processing and storing the filled jars.
While these processes can be long and tasking, the truth is that it is likely to become quicker as you continue to perfect it.
Jars have a long life span even though the upfront cost could be expensive, it still makes a whole lot of sense because all you need to do is to replace the snap lids which are responsible for sealing the food and it costs little.
It is not out of place to say that drying is one of the oldest techniques which hampers the decomposition of food products.
In fact, the process of drying is seen as the easiest and the cheapest way to preserve food without refrigeration.
Do not forget that bacteria, mold and mildew usually thrive in an environment that is moist.
This is why drying is such effective because it tends to remove all the water and can be safely stored for longer periods.
Food stuff like vegetables and fruits can be dried by the wind and sun but if not available, then there is actually nothing wrong in using an in built fire inside the building to provide the required heat for the drying.
Apart from that, you can also buy food dehydration if affordable or check the possibility of using a low temperature oven.
It is important to note those dried fruits especially fruits can be eaten as it is or soaking it in water for sometimes to re-hydrate it.
Salt Curing and Brining:
This is an old food preservation method especially when it involves meat preservation.
The issue about salt is that it creates a hostile environment for bacteria making it impossible for them to leave.
Note that bacteria and most microorganisms cannot live in a salt concentrated environment of about 10 percent and above.
In curing, salt and sugar are mixed and rubbed into some pieces of fresh pork as you store it in a cool temperature.
However, brining starts at the same as salt curing but the main difference is that it is meant to use an additional salty brine solution.
It is important to note that this solution must be changed regularly.
When meats are preserved through salt curing, it is important to soak them in water to remove the excess salt and bring it down to a manageable and edible level.
