How To Preserve Food?

In this brief guide, we are going to answer the question “How to preserve food?”, and discuss the different methods of preserving food and the potential implications of preserving food.

How To Preserve Food?

There are many ways to preserve food at home. You can preserve foods by canning, dehydrating, fermenting, infusing, dry-curing, and many more.

 How to preserve food by Freezing? 

Freezing is a great way to get done with home food preservation. The method of freezing is incredibly easy and versatile. It works for a wide range of foods starting from meats and dairy to fruits and vegetables. The disadvantage being it relies on electricity to stay cold and keep your food from spoiling.

No matter what, freezing is still an important food preservation method in today’s world. Homesteaders rely heavily on not their home freezers to put up a large part of their garden harvest or freeze it until they can get around to canning it or preserving it soon enough.


How to preserve food in Cold Cellaring/Root Cellaring?

Cold cellaring is one of the easiest forms of food preservation. It’s even easier than freezing because it requires almost no prep work. Although it does require access to a root cellar or at least a cold room in the house or garage that will keep foods cool and moist.

Vegetables can be preserved whole and raw in a cold cellar. 

Ferments like sauerkraut and kimchi also store exceptionally well in a cold cellar too. 

How to preserve food in Water bath canning?

Canning is also one of the methods best used for the preservation of food. 

There are two types of home canning: water bath canning as well as pressure canning. Water bath canning is the most accessible form since it doesn’t require much of the special equipment. Water bath canning is safe for jams, jellies, salsa, pickles, most sauces, canned fruit, pie filling, and generally safe for all acidic fruits and vegetables with a PH level of 4.6 or less. 

How to preserve food by Pressure Canning?

Pressure canning is the source of most home food preservation nightmares. Although pressure canners are made with all sorts of safety features, unsafe canning practices can still run anyone to the risk of botulism.

However, as long as one follows safe canning practices, pressure canning is extremely safe and easy. 

How to preserve food by Dehydrating?

Dehydrating is another way to preserve food. The worst that will happen is molds will grow and the food will have to be thrown out.  There is no worry about botulism or food poisoning with dehydrated foods.

A home oven at the lowest temperature can be used or the food can be dried in the sun. All that is needed to be done is lay the food out, set the temperature and the time, and let the dehydrator do the rest. It allows making healthy snacks at home. 

How to preserve food by Fermenting?

Fermenting is another ancient form of food preservation that can seem a little intimidating to many people at first. Fermentation is definitely not the same as spoiled food. It’s the exact opposite since the lactic acid produced during fermentation acts as a preservative. 

It is used to produce and preserve all sorts of foods and beverages, from beer and wine to yogurt and pickles, sauerkraut and kimchi to kefir and kombucha… all of these foods are made possible thanks to the process of fermentation, which has been used to brew beverages and preserve foods. Also,  fermented foods are full of healthy probiotics that are great for supporting healthy gut bacteria and overall health and immunity.

Fermentation requires no special equipment other than glass jars, some cheesecloth, and some sort of weight to keep certain foods below the surface of the liquid.  

How to preserve food by Infusing?

An infusion is made by immersing herbs in a liquid solvent and infusing the properties of that herb into that solution. The solid matter is discarded and the liquid infusion is reserved and used, usually either as food or medicine. Fresh or dried herbs can also be used for infusions. 

How to preserve food by Dry Curing & Smoking?

Both salt and sugar are known to inhibit microbial growth and have been used as preservatives. 

Salting is used predominantly to cure meats but one can also preserve herbs in salt, as well as citrus fruits. Sugar is also used in tandem with salt and spices when dry-curing meat.

Smoking, on the other hand,  is an extra step in the curing process for most meats and seafood. Some salt-cured meats can be stored in a root cellar as well.
